About Tiger API
Tiger is a free and open source API client for developers who want their work to stay theirs. Every request is a plain text file you keep in Git, so you can branch collections and review API changes in pull requests like any other code. No account, no forced cloud sync, no per-seat pricing. It runs fully offline, supports OAuth, proxies and client certificates, GraphQL and SOAP, request chaining and scripting, and ships an MCP server so AI assistants like Claude and Cursor can run your requests.
I build and maintain Tiger on my own time and give it away for free. If it replaced a paid plan for you or just made your day easier, a coffee helps me ship new features and keep the project independent and account-free. Thank you for the support.
