What is it?

This repository is the home of Builder.io's visual development tooling. It contains the SDKs that connect an existing site or app to Builder, along with usage examples, starter projects, and plugins. Developers can use the platform to edit pages visually with their own components, or to turn Figma designs into code.

Builder works with existing components rather than replacing them. Teams can publish content updates through a drag-and-drop editor, or export generated code. The SDKs cover frameworks including React, Vue, Svelte, Qwik, Angular, Next.js and Gatsby, with React Native also listed among supported stacks.

The repo is split into packages (SDKs), examples, starters, and plugins, so developers can pick the integration that matches their framework. A hosted account is available for trying the platform.
