Bit is a software development platform for organizing source code as components that can be reused across applications. Developers can assemble components, pages, and features into app shells, while Hope AI can generate component boilerplate, tests, and documentation. Its built-in MCP server supports working with Cursor or GitHub Copilot to create and reuse components. Bit says it fits standard JavaScript ecosystem tools, with official starters for Node.js, React, Vue, Angular, Next.js, Stencil, Lit, React Native, and plain HTML. Remote component scopes can be hosted on bit.cloud for free or self-hosted. For code review, Bit’s visual review process works alongside GitHub, GitLab, or Bitbucket review. Bit Cloud describes deployment for connected frontends and services with a database, domain, and SSL. Each app gets managed MongoDB on first deployment, with distinct databases for production and preview environments. Bit Cloud also includes approvals, permissions, policies, and audit trails. The product is available on web, Android, and iOS, as well as through API and self-hosted options. Hope: Anything App is available natively for iPhone, iPad, and Android. The company behind Bit is Cocycles Ltd. The Bit / Open Source plan costs 0.00 USD per free, and Bit Cloud offers free personal use.
