About context7

Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Context7 fetches up-to-date code examples and documentation right into your LLM's context. No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

Set up Context7 for your coding agents with a single command. The ctx7 CLI requires Node.js 18 or newer.
