Bit vs Handoff

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.

Handoff is an open-source tool for design system documentation and automation for teams and AI agents. A browser UI, REST API, and MCP server all read from the same underlying data. Figma is the only source currently wired up: a workspace can pull design tokens from Figma and push tokens, components, documentation, and assets to a registry. Handoff can create documentation pages for React and other component libraries, including live previews, properties, and tokens. Its token pipeline converts Figma tokens into CSS, SCSS, Tailwind, and DTCG outputs. Compatible agents such as Claude, Cursor, and Windsurf can access design system data through the MCP server; agents can also create component pages and usage guidelines for team approval. A promptable design space supports exploration with approved components, tokens, and brand patterns. Workspaces can use local filesystem-backed mode or a Postgres-backed registry, deployable with Docker or Vercel. The docs describe 56 MCP tools across 12 categories and an OpenAPI 3.1 specification for each registry’s REST API. Each registry currently serves one workspace, and the handoff-app package requires Node 20.9 or later. Other data sources and destinations are future direction, not shipped connectors.
