Voiden – a free, offline, Git-native API Client
Hey HN! Aldin here, a helping hand to Voiden (https://voiden.md) Voiden is a free, offline, Git-native API client. Your API definitions, docs, and tests all live together. It came out of years of frustration: cloud sync lock-in, paywalled basics, bloated UIs, and lag on even simple requests.

In plain words
Voiden is a free, offline API client that stores API definitions, documentation, and tests in a single Git-native workspace. Designed for developers frustrated with cloud lock-in and bloated interfaces, it works entirely locally with no login, telemetry, or subscription required. API specs live as markdown files alongside requests and docs, with a built-in terminal for version control operations, ensuring documentation stays synchronized with actual API behavior.

Hey HN! Aldin here, a helping hand to Voiden (https://voiden.md) Voiden is a free, offline, Git-native API client. Your API definitions, docs, and tests all live together. It came out of years of frustration: cloud sync lock-in, paywalled basics, bloated UIs, and lag on even simple requests. So the team built the opposite: an offline tool with no login, no telemetry, no lock-in. Just markdown and hotkeys. It behaves like code: local files, git branches, no cloud nonsense. Terminal is built-in, so you can commit, diff, and push changes right from the app. Docs stay close to your requests, so that API spec and what the API actually does never drift apart. No more scattered Postman, docs, and test files everywhere. A single source of truth. A minimalist GET request looks something like this: GET https://dummyjson.com/posts Just hit /endpoint, paste the URL, and run it with Cmd/Ctrl + Enter. Not OSS (yet), but 100% local and free. Optional plugins will be coming down the line, but the core stays free. We'd love feedback from folks tired of overcomplicated and bloated API tooling.
