Tiger
Test REST, GraphQL, and SOAP APIs using a git-native, local-first client with built-in MCP server integration for AI assistants.
Tiger is a free, open-source API client that serves as a privacy-focused, offline-first alternative to Postman, Insomnia, and Bruno. Storing every request as a plain-text .tiger file directly in your file system, it seamlessly integrates with Git workflows for straightforward version control, branching, and pull request reviews without tracking or telemetry. It supports REST, GraphQL, and SOAP requests, features sandboxed scripting with broad Postman and Bruno compatibility, and provides a built-in Model Context Protocol (MCP) server that empowers AI assistants like Claude and Cursor to inspect and run your saved API requests directly from chat.
