Yaak is an open-source, local-first desktop API client for sending HTTP, GraphQL, WebSocket, Server-Sent Events, and gRPC requests, built with Tauri, Rust, and React. It stores data locally as plain files for Git sync, requires no account, includes an agent-friendly CLI, and is free for personal use with paid licenses for commercial use.
Use cases
- send and organize REST API requests from a desktop app
- test GraphQL queries and pick operations by name
- debug WebSocket and Server-Sent Events connections
- call gRPC endpoints without writing code
- migrate from Postman or Insomnia
- sync API collections via Git with plain-text files
- let AI coding agents create and send API requests via CLI
- authenticate requests with OAuth 2.0, API keys, or 1Password
When to choose
- you want a fast, privacy-first, offline-capable API client with zero telemetry
- you need one tool covering REST, GraphQL, gRPC, WebSocket, and SSE
- you want request collections stored as plain files for Git versioning
- you're looking for a Postman/Insomnia alternative that works without an account
- you want an API client that AI agents can drive through a CLI
When to avoid
- you need a commercial-use tool without purchasing a license
- you require browser-based or team-cloud collaboration features out of the box
- you depend on Postman-specific ecosystem features like extensive integrations or mock servers
- you need a headless CI-only HTTP testing tool rather than a desktop GUI
