Overview

Builder.io is a visual development platform that connects to an existing site or app, so pages can be edited by drag and drop or generated from Figma designs using your own components. Changes are exported as code or published through SDKs. This repository holds the SDKs, usage examples, starter projects and plugins; the editor itself is used through a Builder account.

Who it is for: Frontend teams adding visual editing to an existing site

Strengths

  • Renders pages from your existing components via SDKs
  • Imports Figma designs and exports them as code
  • Repo bundles SDKs, examples, starters and plugins in one place
  • MIT licensed, TypeScript codebase

Weaknesses

  • Editor is used through a Builder.io account sign-up
  • README gives no self-hosting instructions
  • Monorepo of SDKs and examples, not a standalone app

What it needs

  • TypeScript
  • Needs Builder.io account

Quick answers

Is builder open source?
