Context7 vs refact

Context7: Context7 is an MCP server that injects up-to-date, version-specific library documentation directly into LLM prompts. Add "use context7" to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor.; refact: Refact.ai is an open-source AI Agent designed to automate complex, multi-step software engineering tasks by deeply understanding codebases and integrating with various development tools. It offers features like context-aware auto-completion, in-IDE chat, and support for a wide range of LLMs and programming languages, with options for on-premise deployment.

TL;DR

Context7 logo
Context7Code Assistant · ★ 63.5k
When to choose:
  • You use Cursor, Claude Code or another coding agent with fast-moving public libraries and want current, version-specific docs and examples.
  • You want the least setup: `npx ctx7 setup` signs you in and configures the skill or MCP server for your agents.
  • You want to work with or without MCP: the CLI plus skill mode fetches docs without an MCP server.
When to skip:
  • You need docs for internal or private libraries: a self-hosted index fits better.
  • Your data policy rules out sending queries to an external service: requests go to Upstash's hosted backend.
  • You need a fully open-source stack: only the MCP server is open source; the API backend, parser and crawler are private.
