Source: https://altcatalog.com/alternatives/yaak/ Category: API clients ## Overview - **Who it's for**: Developers and teams who test and manage REST, GraphQL, gRPC, and WebSocket APIs and want a Postman/Insomnia alternative that keeps data local rather than in a vendor cloud. - **What you get**: A desktop API client supporting HTTP, GraphQL, gRPC, WebSocket, and SSE requests, with OAuth 1/2, AWS v4, JWT, Basic, Bearer, and API Key authentication. Requests, environments, and variables are stored as local files that sync via Git (or Dropbox), with optional ChaCha20-Poly1305-encrypted secrets in the OS keychain. It imports existing collections from Postman, Insomnia, OpenAPI, Curl, and Swagger. It's open source (MIT license), has no telemetry, and doesn't require an account. - **How it works**: Yaak runs fully offline as a native desktop app with no cloud backend; requests and config are saved as plain-text files on disk that Git can version and diff like code. ## Profile - **License**: MIT (verified 2026-07-08) - **Pricing model**: Freemium (verified 2026-07-08) - **Starts at**: Free (verified 2026-07-08) - **Platforms**: Windows, macOS, Linux - **Status**: active (verified 2026-07-08) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Bruno](https://altcatalog.com/alternatives/bruno.md) | 100 | MIT | Windows, macOS, Linux | | 2 | [Insomnia](https://altcatalog.com/alternatives/insomnia.md) | 100 | Apache-2.0 | Windows, macOS, Linux | | 3 | [Hoppscotch](https://altcatalog.com/alternatives/hoppscotch.md) | 85 | MIT | Web, Windows, macOS, Linux | | 4 | [Postman](https://altcatalog.com/alternatives/postman.md) | 78 | Proprietary | Windows, macOS, Linux, Web | | 5 | [HTTPie](https://altcatalog.com/alternatives/httpie.md) | 55 | BSD-3-Clause | Windows, macOS, Linux, Web | Alt Score = Verified coverage (90%) + Visibility (10%).
