Your quick-start guide for learning how to code on HubSpot.
Let's dive into the tool and learn by completing this simple activity.
Let's Build!
👉 Complete this short activity

It’s time to jump in the CMS Hub and get our hands dirty. Here is a really simple activity for you to follow to help learn the key elements of CMS Hub.

   -   For this activity, we will be using the in-app Design Manager.

   -   This activity should take you 15-20 minutes to complete.

   -   You will need to have both the Discovery Kit and the CMS app open in separate windows.

   -   Ask questions in the Developers Slack if you have questions

Let’s get started!

  • 1) Open your CMS sandbox account in a new window    Expand this section

    1.1) You will want to have both this screen and your CMS sandbox account open, side-by-side. 

    Dual Screens

    👉 If you don't already have your account open, click here to login

    👉If you do not already have a CMS sandbox account, click here to create one

    Once you have them both open, continue to step 2. 

  • 2) Have both Discovery Kit and CMS App open in two windows     Expand this section

    Have both this Discovery Kit and the CMS app open in separate windows. This will make it easy to follow the instructions here while implementing them in the CMS app. 

  • 3) Create your template     Expand this section

    In CMS Hub, everything is built in a very modular format. Templates are the "glue" that hold together all your individual modules. Additionally, all pages are then created using templates in your library. 

    Let's create your first simple template! 

    3.1) Open the Design Manager Tools in a new tab

    HubSpot CMS Design Manager
    3.2) Create a new folder - Click "File" -> "New Folder".

    3.3) Create a new template file - Click "File" -> "New file in Templates" and complete the details. 

    Creating a template in HubSpot CMS
    3.4) Your template will auto-save, however, click the "Publish changes" button to publish the template and make it available for use.

  • 4) Add a default module     Expand this section

    Modules are the individual building blocks that make up all templates and pages. HubSpot has a number of built-in default modules. Let's add one to your template. 

    4.1) Click the "+ Add" button, choose a module, and drag-n-drop it into the template. 
    Add default module into Hubspot CMS template

    Building Custom Modules 🤖
    Modules are the building blocks of templates. The default modules will get you started, however, most CMS developers build their own custom modules. 

    For those who build in WordPress, you can think of custom modules as a mix of template partials and custom fields. Using custom modules will result in a really great editing experience for marketers and content creators. 

    You will learn more about custom modules in the "Let's Explore Deeper - Building Modules" section below. 

  • 5) Install a free module from the HubSpot Marketplace     Expand this section

    Let's add a second module into your template by installing one from the HubSpot Marketplace. 

    5.1) On the main menu, click on "Marketing" ->"Files and Templates" -> "Template Marketplace"
    Navigating to HubSpot Marketplace in HubSpot CMS
    5.2) Pick your favorite free module and install it in your portal.

Exploring workflow options

HubSpot offers three different options for building on HubSpot CMS - The visual editor, an in-app Design Manager, and local development. Different people will use different workflows based on their technical skill level.
  • Workflow 1: Visual Editor     Expand this section

    The visual editor within the HubSpot CMS features offers a friendly editing experience for marketers and content creators.

    If you're a developer who wants more control over the pages your marketing team creates, you'll also have the ability to set guardrails on elements that are static vs. move-able and editable vs. non-editable. 
    HubSpot Page Editor
    With the visual editor, the marketer has the ability to start with a template and add or rearrange modules to create the pages they want to create quickly and easily, without needing to go into the code. Anyone who has used WordPress, Wix or Squarespace will be able to jump into HubSpot CMS without missing a beat. HubSpot WYSIWYG editor for the HubSpot CMSWe've worked hard to create an experience that will transform the way website creation happens on HubSpot; where a developer can create a modular and flexible website for the marketer.

    The developer can then focus on the styling and design of the website, leaving the marketer responsible for layout tweaks and content creation.

    We're working toward a world where the developer doesn't need to waste time making small changes on endless numbers of pages--they can create a few key templates with drag and drop areas in the body, and the marketer can take care of the rest.

  • Workflow 2: Design Manager     Expand this section

    We recently launched new training videos around each area of the in-app development experience.  Watch our developer tours of:
      - Design Manager and page editor
     - File manager
     - Settings
     - Navigation

    But - if you prefer to read, keep scrolling down :) 

    The second development option with HubSpot CMS is using the in-app Design Manager.

    This workflow option offers the ease of visual development with the flexibility of coding where necessary.
    HubSpot CMS Design Manager and IDE
    The Design Manager consists of three windows...HubSpot CMS Design ManagerThe Finder  -  The finder is designed to provide an asset navigation experience equivalent to a computer operating system. Common file and folder operations such as creation/deletion and searching/sorting are available via the finder menu or right-click contextual menus on each asset. (learn more)

    The Editor  -  The editor is the central section of the design manager where you’ll do the lion’s share of your work. It is either a drag and drop interface or a code editor depending on the asset you are working on. (learn more)

    The Inspector  -  The inspector allows you to add and edit components in a template or module. It is contextually dependant on the task you are performing and the type of file.

    For example:
     -  When a component is selected in the drag & drop editor, the inspector will show all of the features and options of that component.
      -  When no component is selected in the drag & drop editor, the inspector will show options for the template itself.
      -  When editing a module, the inspector allows you to edit and add fields.
      -  When editing an HTML, CSS, or JS file, the inspector does not appear.

Creating templates

(prefer to learn with videos? - Check out our HubSpot Academy video training on HubSpot CMS templating)

HubSpot allows you to work in a very modular format where a collection of modules can be connected into a template.

The most fundamental aspect of templates is their relationship to pages. Every page published on the HubSpot CMS is created from a template. The template file controls the layout, style, and functionality of the page. It's where you stitch together your HTML, CSS, and JavaScript.
Three key points to understand with templating:

1. When you're building templates, you're building the editing experience for the person who will be creating pages from your templates.

This allows content creators to do their job without having to collaborate with designers and developers during every step of the process.

2. The real power of templates is the ability to create reusable and modular elements. The relationship between templates and pages is not one to one. It's one to many. One template may be used to create dozens of pages.

3. Elements that make up a template may be shared by dozens of templates. Experienced CMS developers leverage this to create a tightly organized network of components and boost efficiencies.
This allows content creators to do their job without having to collaborate with designers and developers during every step of the process.

  • How to build website templates in HubSpot CMS     Expand this section

    There are two ways to code templates in HubSpot CMS:
         1 - Drag-and-drop templates (HubSpot recommends)
         2 - Coded templates

    Drag-and-Drop Templates
    Drag-and-drop templates are created in the 
    design manager. Here it manages your layout HTML for you behind the scenes in order to preserve the ease-of-use for the end users of the template - marketers and content creators.
    Mockups to Template Layout in HubSpot CMS

    What this looks like in the Design Manager tool (see more here)
    Building a template with drag-and-drop editor in HubSpot CMS

    With drag-and-drop templates, the developer can set up guardrails around what can be edited, then the marketers can jump in to update/manage/build pages in the visual editor without breaking the page or bugging the developer for little updates.

    The end result for marketers will look like this…

    - Setup Your Site’s Navigation Menus
    Training video on templates from HubSpot Academy

    Coded Templates
    The second option is 
    building coded templates. With coded templates, you can write everything from scratch and have more flexibility as a developer. The trade-off with coded templates is that marketers and content creators will not be able to take advantage of the drag-and-drop interface in the visual editor. They can not change the page layout and are restricted to only editing existing content. Any updates to the template must be done in the coded file by a developer.

    An important note - HubSpot’s drag-and-drop system uses the Bootstrap 2 framework. As a developer, if you would like to code in Bootstrap 3, 4 or another framework you MUST use the coded template method. When you do, you lose the ability for marketers and content creators to use the drag and drop visual editing experience. Tradeoffs.

  • Groups in HubSpot templates     Expand this section

    Components in the drag-and-drop editor are either modules or groups of modules. Modules are the building blocks, and groups tie modules together either for layout purposes or for editing purposes.
    Creating groups and modules groups in HubSpot CMS templates
    In the drag-and-drop editor, you can create groups and subgroups. You can drag these elements around in the editor to quickly build layouts and target CSS/JS to a specific group. Any group of modules can be turned into a global group to be used on any template in your account.

  • Flexible columns in HubSpot templates     Expand this section

    Flexible columns are sections of your template that can be edited and restructured by marketers in the visual editor.

    When building the template, developers can add in the flexible columns and set guardrails.
    Adding a flex column in HubSpot CMS template
    From there, marketers will be able to manage all of the updates and changes in the visual editor. The end result for marketers looks like this...
    Marketer page editing in HubSpot CMS
    Using flexible columns in your templates will save time, reduce headaches, and free up your time as a developer so you can focus on more complex coding challenges. Non-technical folks will be empowered to update page layouts and edit content, instead of bugging you about it.

  • The HubSpot Marketplace - templates     Expand this section

    Just like in other CMS platforms, HubSpot CMS allows developers to build and sell modules and templates to extend the functionality of the core CMS.

    The HubSpot Marketplace is like the iTunes of HubSpot. It is the centralized place to see what modules are available. Community developers submit modules and templates for other HubSpot users to install into their HubSpot CMS.

    Side Note - Becoming a HubSpot Marketplace Provider to sell modules and templates is a great way to generate leads for your web agency and create an additional revenue stream - Learn more!

    Pro Tip - When learning how HubSpot CMS works, it's smart to install a number of free templates and modules from the Marketplace. Once installed, it's easy to review the code to better understand how it was created.

Building modules

  • Built-in modules     Expand this section

    HubSpot CMS comes with a number of built-in modules right out of the box.  Additionally, there are a number of free modules in the HubSpot Marketplace that can be easily installed to increase the available modules. 

  • Custom modules     Expand this section

    Custom Modules allow you to expand on your HubSpot portal and create repeatable, reusable, and sometimes dynamic content to enhance your website and make it easier for content editors to build HubSpot pages in a fast and efficient way.

    Because the CSS and JS are built into the module, the marketer can drop this anywhere, and it will function exactly the same. The marketer also only has access to what they need, and if the developer or designer needs to make changes, they can make them in a singular place.

    Custom modules make the web development experience far more like building an application than the traditional website format.

    Custom modules function similar to many WordPress plugins with the exception of you don't always have to load the code for the module on every page on your site. Those who are familiar enough with HubL, HubL functions/filters, HubDB, and the HubSpot APIs can essentially recreate many of the most popular WordPress plugins out there. 

    Like to play around? Custom modules are also a very safe place to try and to break new things. 

    👉 Learn more about modules in HubSpot CMS by taking our Academy CMS developer training.

  • Global modules and groups     Expand this section

    When designing a site, there may be sections of the page that you want to keep reusing across your entire site. With the design manager, you can create global content to reuse across any template.

    Global content can be composed of either a group of content modules or a single content module that makes up an essential element of your website pages. This is content that you want to create once and then add across various locations on your site.


    How do I make a global module or group?

    While in the design manager, select the specific module or group that you’d like to convert into a global element. Once selected, click the “more” drop-down menu on the right side and click “Convert to Global”.
    HubSpot CMS - Creating a global module or group
    Once converted, the module or group will appear in your +add module options in any of your templates.

    Please note: when edited, changes to a global module or group will apply across every website page that uses the global content in its template. Flexible columns and custom coded modules cannot be used in global groups.

Learning HubL markup

HubL is a HubSpot's templating language which allows developers to build powerful and dynamic websites, with minimal code.

HubL can be used to dynamically render content, as well as generate easy to edit modules within the content editors marketers work in so they do not ever need to touch the underlying HTML of a template. This allows for many pages to use a single template, making managing content and websites significantly easier and quicker.

HubL is the coded version of the Design Manager’s drag and drop functionality, allowing for further and full customization of the html output of a website, when your templating needs go beyond the capabilities of the drag and drop template editor.

As an example of its power, a function as simple as HubL-Code-Snippet adds a listing of blog posts from your HubSpot blog based off of a set of parameters shared by posts across blogs.
  • Learning HubL     Expand this section

    The Syntax  -  HubL follows the general syntax of the templating language it was forked from, Jinja. Additionally, if you're familiar with templating in Shopify, you'll pick up HubL rather quickly.

    While  the `` symbols are different from `<?php` and `?>` the languages are similar enough that you can probably read most HubL code if you have a basic understanding of PHP.

    Learning HubL  -  Learn all of the HubL syntax, filters, variables, loops, functions, and tags in our Intro to HubL Documentation. 

  • In-App HubL Reference Tool     Expand this section

    Have you ever been in the middle of coding and you happen to forget the syntax for the specific language you're working in?  HubSpot makes it easy to quickly pull up the latest HubL token syntax while coding in-app.

    Click on the "HubL Reference" tab at the bottom right of the screen. 

Extending HubSpot CMS
  • HubDB - HubSpot's in-app database     Expand this section


    HubDB is a semi-relational data store within HubSpot that allows developers to easily create database-driven content embedded within website and landing pages, and marketers the ability to easily update content within the database. The HubDB user interface is represented as rows, columns and cells in a table, much like a spreadsheet.
    HubSpot CMS - HubDB relational database

    The data in a HubDB table can be used to render content on live pages using HubL or the HubDB API. This allows data to be managed and updated in one place, while dynamically rendering content based on the table data on live content. It can additionally be used to generate unique pages for each table row, using HubDB Dynamic Pages, creating a dynamic and powerful collection of pages with little effort to create and manage all of these pages.

    Developers should think about HubDB as a database of information which can be managed and edited in one place, and use the various HubDB content rendering options to build dynamic and easy to manage websites. Marketers can easily edit the HubDB table data, and developers can build websites around tables, allowing for powerful and efficient management of content by marketers without having to touch pages or templates to generate new content.

    Watch the HubDB video lesson.

  • HubSpot APIs     Expand this section

    Although HubSpot does not give developers direct access to the tool’s backend, you can achieve a great deal of flexibility using the ever-growing library of HubSpot APIs.

    The API is built to allow you to create a functional application or integration quickly and easily. We know from experience - these are the APIs that power the HubSpot application. The ecosystem of developers creating integrations on top of the APIs is strong and diverse, ranging from webinar providers to CRMs to social media.

    All of the HubSpot APIs are organized around REST - if you've interacted with a RESTful API already, many of the concepts will be familiar to you. All API calls to HubSpot should be made to the base domain. We use many standard HTTP features, like HTTP verbs, which can be understood by many HTTP clients. JSON will be returned in all responses from the API, including errors. The APIs are designed to have predictable, straightforward URLs and to use HTTP response codes to indicate API errors. - continue reading the HubSpot API overview here.

  • Dynamic Personalization     Expand this section

    One stand-out feature of the HubSpot CMS is “Smart content”. Smart content refers to the ability to dynamically change the website experience and content a visitor sees based on the data we know about them.
    HubSpot CMS Personalization Example
    This could be anonymous data collected (ex: device type, IP location, referral source, etc) or data that has been collected in forms or in the HubSpot CRM (ex: lifecycle stage, list membership, persona, etc).
    HubSpot CMS Personalization Criteria
    The smart content types include rich content modules, HTML modules, forms, or call-to-action modules. Additionally, you can use personalization tokens to insert known data into the front-end of the website.

    This powerful feature is quite unique to HubSpot CMS as it's the only CMS that has a CRM built directly into the platform.

    Best of all, smart content is a feature that can be coded into the website by the developer and then fully managed and updated by marketers or content creators.

  • The HubSpot Marketplace     Expand this section

    The HubSpot Marketplace is a storefront that allows developers to sell website assets (currently Templates & Modules) to HubSpot customers. The storefront offers seamless integration with a customer’s HubSpot portal which allows for instant access to any purchase in the Marketplace with no installation required!
    HubSpot CMS Marketplace
    Simply select the asset you'd like to add to your portal. Once added, the asset will display in your available list of templates or modules. 

    Who uses the HubSpot Marketplace, and why is it important?
    The HubSpot Marketplace is used by many HubSpot customers. It is useful when onboarding on to HubSpot, or when looking for a website redesign to easily find a design that matches the desired look and feel of a website. In addition, the HubSpot Marketplace recently added the ability to offer modules as unique assets, which allows customers to find solutions for unique website elements such as galleries, calculators, and other widgets.

    Along with an offering website templates, the HubSpot Marketplace also offers a wide variety of email templates to fit any need from general emails, to newsletters and events.

    How should a CMS Developer and web design agency think about the HubSpot Marketplace?
    The HubSpot Marketplace allows for several opportunities depending on what type of business a developer wants to create.

    The most common type of business is to create and list a set of assets for sale in the Marketplace that generates income when HubSpot customers purchase them.

    However, there has been an additional approach that has also proven successful. HubSpot creates a lead contact record for each HubSpot customer that purchases (or downloads for free) an asset from the Marketplace. Providers can then create lists and workflows to follow up with customers to offer additional assets or services to increase revenue.

Generally speaking... if you can dream it, you can build it. Between the flexibility of the CMS, HubL, HubDB, etc. and our ever-expanding APIs... you as a developer have the creative freedom to build the functionality you need.

You can view a small sample of CMS Hub websites here.

That said, there are some scenarios where HubSpot CMS may not be an ideal option.

CMS Hub does not have any built-in e-commerce functionality. Building a robust eCommerce platform is a huge undertaking. Instead of reinventing the wheel, we partnered with Shopify to build a deep integration. Shopify+HubSpot gives you an extremely powerful option for building eCommerce solutions.
Large, complex enterprise websites
As a whole, HubSpot’s primary focus is on helping millions of small (1-20 employees) and mid-sized (20-2000 employees) companies grow better. We are not building solutions for the Fortune 500.
If your website is monstrous, very complex, and requires many permissions… CMS Hub may not be a good option. Of course, work with the HubSpot sales engineers to understand what you’re trying to accomplish and if CMS Hub could be a viable option.


If you have more questions about CMS Hub and it’s viability for your project, please as technical questions in our CMS Developer Slack or chat with our sales engineers.

You do not have access to the backend of HubSpot CMS. You do have full access to the front-end of the existing platform and use of external proxy servers.

That said, we are working extremely hard to make HubSpot easy to build on top of via our APIs. We have been making heavy investments to build a robust set APIs and are continuously launching new endpoints and APIs - this will only accelerate over time.

You can view all available APIs and endpoints here.

It is possible, however, there are some trade-offs to consider. 

The HubSpot visual editor uses the Bootstrap 2 framework to allow the drag-and-drop functionality. This functionality makes it very easy for marketers and content creators to adjust page layouts and manage updates.

HubSpot CMS visual editor - drag-and-drop

Empowering non-technical folks to make updates means your time, as a developer, can focus on more complex projects. 

That said, it is possible to code in Bootstrap 3, 4 or another framework. To do this, you MUST use a coded template instead of the design manager.

The tradeoff is when doing coded templates, you lose the ability for marketers and content creators to use the drag-and-drop visual editing experience.


HubSpot recommends coding for the end-user, marketers and content creators. Yes, it means compromising on using Bootstrap 2, however, overall this approach will make your life easier, empower your team, and make you look like a rockstar. 

Note - In order to submit any modules or templates in the HubSpot Marketplace, they must be coded for the drag-and-drop editor. You can learn more about submission guidelines here.

The short, honest answer is, no. Sass and LESS CSS frameworks are not currently supported by HubSpot's in-app Design Manager.

One workaround - If you're developing locally, it is possible to use Sass/LESS and push to the design manager using Gulp.

Speed, security, and reliability are HUGE priorities for us. We view them as the essential foundation of any high performing website.

Our new "CMS for Developers Certification" is coming soon! :) 

We have already released all of the content in our learning center and are currently organizing the practicum and certification criteria.

We hope to have the certification live in Q1 2019. Please join the CMS Developers Slack and/or subscribe to the blog for updates.

What Developers are Saying

HubSpot's CMS continues to improve and has a swell user interface. The community around it is pretty supportive and we all seem to help each other. The new design manager really makes creating modules a breeze. This rivals Advanced Custom Fields on WordPress, and is a much better implementation of it.

While CMS’s like WordPress have large yet cold communities where it’s everyone for themselves and the only resources available are outdated blog posts. You’ll find that HubSpot developers tend to be more engaged and see discovering and sharing new methods of doing things as a collaborative gain. If you give back to the community you’ll receive ten-fold.

The best thing about the CMS Hub is that it is everything in one package. HubSpot allows us to slim down our project Tech Stacks, which in turn make things easier for our marketers and clients. The less I have to spend time making small updates to content, the more I can spend my time building new modules and templates.

The HubSpot community is growing and new tools are consistently being added to what is fast becoming an extremely competitive development platform. It feels like a gold rush working in HubSpot because the community is still very tight-knit but the clientele tend to be more well-funded, leading to a lot of opportunities work with some great up-and-coming and well established inbound marketing-minded companies. The community is very active. The template marketplace allows for another great opportunity to sell your work and meet new clients..
