Builder.io features and specs

  • Visual Headless CMS
    Visual CMS is a headless content management system (CMS) that helps digital teams build, ship, and iterate content significantly more efficiently by giving marketers a drag-and-drop interface for building and editing digital experiences without depending on developer support. It integrates with existing components and any modern tech stack so developers can work more efficiently to ship high-performance web and mobile experiences for any scale.
  • Visual Copilot
    Visual Copilot is an AI-enabled design-to-code tool that helps digital teams automatically turn Figma designs into code that's as clean, semantic, and accessible as the code a developer would have written themselves. Unlike other design-to-code tools, it automatically makes designs responsive, lets you chat to iterate the code with AI, and generates code that leverages your existing components when you have them.

Questions & Answers

As answered by people managing Builder.io and Flagsmith.

What makes your product unique?

Builder.io's answer

Builder is driving the next generation of front-end programming, with the only Visual Development Platform that offers an AI-powered design-to-code tool, a visual editor, and an enterprise CMS.

What's the story behind your product?

Builder.io's answer

Our founders, Steve Sewell and Brent Locks, met on the campus of UC Berkeley in 2011, and have been friends and colleagues ever since. In those early days, they bonded over wanting to be entrepreneurs, and having lots of ideas, but not knowing how to code to bring them to life.

Fast forward more than a decade, and Steve is now a visionary technologist (Brent's words) and Brent still doesn't know how to code (beyond some basic HTML and CSS), but they continue to share a passion around building technology that can enable anyone to bring their ideas to life, which is at the core of Builder.io.

How would you describe the primary audience of your product?

Builder.io's answer

Frontend engineering leads who manage a headless site or store. Frontend and full-stack web developers whose team uses Figma to design web and app experiences

Why should a person choose your product over its competitors?

Builder.io's answer

Shipping, iterating, and optimizing high-performing digital experiences eats up a ton of time. As a result, teams donโ€™t get nearly as many experiences, pages, content, or experiments to market as they planned. Builder helps teams ship twice as much, without doubling their effort or team size. Builder does this by offering tools that optimize every step of the journey from design through optimization. No other tool comes close because they donโ€™t consider the entire journey and havenโ€™t embedded AI at the same level as Builder. As a result of shipping twice as much with the same team size, companies can significantly increase top-line revenue or decrease costs.

Who are some of the biggest customers of your product?

Builder.io's answer

  • Zapier
  • Anheuser-Busch
  • Everlane
  • JCREW
  • PetLab.co
  • Fabletics
  • Harry's
