Context7

Context7 supplies current, version specific library documentation and code examples to large language models and AI coding tools. Instead of relying on whatever an assistant absorbed during training, a developer pulls documentation straight from the source into Cursor, Claude Code, Codex, Devin Desktop, Antigravity or any other LLM, so answers match the version actually in use and code examples work as written. It is aimed at developers who use AI coding assistants daily and are tired of outdated APIs and invented functions in the output. Context7 exposes a Search API and a Context API that return concise, relevant documentation without filler, and developers can add documentation for libraries that are not yet indexed. Paid teams can also parse private repositories, collaborate in a shared teamspace and control access, with OAuth 2.0 available on every plan. Pricing is published. Free costs $0 and covers public repositories, access control, OAuth 2.0 and 1,000 API calls per month; once that limit is reached, Free users are blocked but receive 20 bonus calls per day until the month resets. Pro costs $10 per seat per month and includes 2,000 API calls per seat, with additional calls billed at $5 per 1,000 and private repository parsing billed at $5 per 1 million tokens. Allocations are per seat and do not pool across a teamspace. Enterprise pricing is custom and adds SOC 2 compliance, SSO over SAML or OIDC, self hosted deployment and dedicated support. Context7 is built and maintained by the Upstash team, and its source is published on GitHub.
