Beak
A free, open-source alternative to Postman for building and testing APIs, that stores your projects as plain git-friendly files instead of locking them into a cloud account.

Description
Anyone who's tested an API has probably used Postman — but Postman increasingly pushes you toward its cloud account, sync, and paid tiers just to keep working the way you used to. Beak takes the opposite approach: it's a free, open-source desktop app for building, testing and managing APIs where your projects live as local files structured like a git repository, so you can version, diff and share them the same way you already handle code.
Beak is a cross-platform (macOS and Windows) API tool with realtime inline variables that recalculate dynamically, tab-based multitasking for juggling multiple API projects, an Omni Bar for fast navigation, and a git-compatible folder/file structure that makes team collaboration and code review of API collections straightforward. Projects are stored locally with built-in encryption rather than a mandatory cloud account, and the app supports an extensions API for customization plus "Variable Sets" for switching between environment configurations. It's fully free, open-source on GitHub, with a modest but active community (~24 stars as of writing).
💬 Our review
The short version: if you're tired of Postman nudging you toward cloud sync and paid plans just to organize your API collections, Beak's local-first, git-compatible, completely free approach is worth trying.
It sits alongside Insomnia, Hoppscotch and Bruno — all of which have moved in the same local-first, file-based direction as a reaction to Postman's cloud-first shift, and Beak is closest in spirit to Bruno specifically. Beak's real edge is the realtime inline variables and git-native folder structure, which make code review of API changes genuinely easy for teams already living in git workflows; the tradeoff is a much smaller user base and community than Postman or even Insomnia, so expect fewer integrations, tutorials and third-party plugins. Good fit for developers who want a lightweight, privacy-respecting API client that plays nicely with version control; less compelling if you need Postman's mock servers, extensive team/enterprise features, or a huge public API collection library.
