Open Source Catalog

Discovery only, not legal advice

Open Source Catalog helps you discover open-source projects. Nothing on this site, in its API, MCP server, chat answers, or exports is legal advice, and using it does not create a lawyer-client relationship.

License information may be wrong

License data is collected automatically from public sources (repository metadata, license files, curated lists) and summarised by heuristics. It can be incomplete, outdated, or wrong. A repository can contain files under other licenses, change its license, or have dependencies with different terms.

Rows marked "Unverified" have not been reviewed by the catalog maintainers.

Before relying on a project, check the license in the original repository and get advice from a qualified lawyer for your situation.

AI-generated answers

Grok chat answers are generated by an AI model (xAI) from catalog data. They can be inaccurate or incomplete. Verify every recommendation.

Third-party content

Project names, descriptions, and links belong to their authors. We do not endorse, audit, or guarantee any listed project, including its security, quality, or fitness for a purpose.
