Context7

Context7 provides your AI assistant with up-to-date, version-specific documentation and code examples for any library or framework. Instead of relying on potentially outdated training data, Context7 fetches live documentation so your AI gives accurate, current answers.

Built by Upstash, Context7 maintains a constantly updated index of documentation for thousands of popular libraries. It resolves library names, fetches relevant docs, and provides code examples that match the exact version you are using.

Essential for developers who want reliable, version-accurate code suggestions and documentation lookups without manually searching docs sites.
