What it is

Bit organizes source code as reusable components that developers can assemble into applications. Components, pages, and features can be composed into app shells, while Hope AI generates component boilerplate, tests, and documentation. A built-in MCP server supports workflows with Cursor or GitHub Copilot for creating and reusing components. Bit says it works with standard JavaScript tools and provides starters for Node.js, React, Vue, Angular, Next.js, Stencil, Lit, React Native, and plain HTML. Remote component scopes can be hosted free on bit.cloud or self-hosted. Its visual review process works alongside GitHub, GitLab, or Bitbucket review. Bit Cloud describes deploying connected frontends and services with a database, domain, and SSL; each app receives managed MongoDB with separate production and preview databases. Cloud features include approvals, permissions, policies, and audit trails. Bit is available through web, Android, iOS, API, and self-hosted options. The Bit / Open Source plan is free.
