Thinking about hiring a HubSpot developer? Understanding the basics helps you make better decisions and communicate more effectively with your development team.

HubSpot development isn't just about building websites—it's about creating powerful, integrated experiences that drive growth. Whether you're evaluating developers or considering building in-house capabilities, this guide covers what you need to know.

What Is HubSpot Development?

HubSpot development involves building and customizing websites, landing pages, emails, and integrations using HubSpot's CMS and CRM platforms. It combines traditional web development skills with HubSpot-specific tools and languages.

Core Components of HubSpot Development

  • HubL: HubSpot's templating language for dynamic content
  • Custom Modules: Reusable content blocks with editable fields
  • Themes: Complete design systems for consistent branding
  • Templates: Page layouts built from modules and code
  • Integrations: Connecting HubSpot with third-party tools

Essential Skills for HubSpot Development

1. Front-End Fundamentals

HTML, CSS, and JavaScript form the foundation. You'll use these to structure content, style designs, and add interactivity.

Why it matters: Even with HubSpot's drag-and-drop tools, custom work requires solid front-end skills.

2. HubL Templating Language

HubL lets you create dynamic, personalized content that adapts based on visitor data, CRM properties, and more.

Why it matters: This is what separates basic websites from powerful, data-driven experiences.

3. Design System Thinking

Understanding how to build modular, reusable components ensures consistency and makes future updates easier.

Why it matters: Saves time and money as your site grows and evolves.

4. API Integration Knowledge

Connecting HubSpot with other tools (CRMs, marketing platforms, analytics) requires understanding APIs and webhooks.

Why it matters: Your tech stack needs to work together seamlessly.

Your First Steps in HubSpot Development

  1. Get a Developer Account: HubSpot offers free developer accounts with sandbox portals for testing
  2. Install the CLI Tools: The HubSpot CLI lets you work locally and sync changes to your portal
  3. Study the Documentation: HubSpot's developer docs are comprehensive and include code examples
  4. Build a Simple Module: Start with something basic like a custom hero section or card component
  5. Join the Community: HubSpot's developer Slack channel and forums are invaluable resources

Common Beginner Mistakes to Avoid

  • Building everything from scratch instead of using HubSpot's built-in features
  • Ignoring mobile responsiveness and accessibility
  • Not planning for content editor usability
  • Overcomplicating modules with too many options
  • Skipping performance optimization

When to Hire a HubSpot Developer

Understanding HubSpot development helps you recognize when you need expert help:

  • You need custom functionality beyond HubSpot's standard features
  • Your site requires complex integrations with other platforms
  • You want to optimize performance and conversion rates
  • You need ongoing development support without hiring full-time
