About Voiden Devtool - API work done better
Voiden is an offline API client that helps developers and QA folks design, test, document APIs, in one place, in plain text executable files. Unlike legacy API tools, Voiden does not force you in a fixed interface. Instead it lets you compose APIs with blocks (headers, auth, params, body). Reuse, replace & version everything just like code, in Git. No telemetry, no VC funding, and no cloud lock-in.

Loving the offline-first approach.. having a full API client that works without a cloud dependency is a game changer. Keep pushing forward!
Great tool for API sharing and collaboration. It removes a lot of the friction from sharing API requests and documentation with teammates.

Voiden has been a great addition to my workflow. It keeps API testing simple, quick, and stress-free, while still feeling polished and reliable. Impressive work from the team!
Love using Voiden! The interface is clean, fast, and easy to use. It makes API testing much smoother and more enjoyable. Great work by the team!

Excited to see this 🚀 I personally Love the idea of keeping API workflows directly in markdown instead of constantly context-switching between tools. The developer experience is super clean already.
Hey there, Voiden is an Open Source API client that brings all API work: specs, tests, docs and context in the same plain executable md file. Inspired by Obsidian and curl. Offline and Free!
