Voiden is an offline-first, git-native API tool built on Markdown - and it very intentionally didn’t start as “let’s build a better Postman”.
Over time, API tooling became heavyweight: cloud dependencies for local work, forced accounts, proprietary formats, and workflows that break the moment you’re offline. Testing a localhost API shouldn’t need an internet connection.
So we asked a simple question: What if an API tool respected how developers already work?
That led to a few core ideas:
-
Offline-first, no accounts, no telemetry
-
Git as the source of truth
-
Specs, tests, and docs living together in Markdown
We opensourced Voiden because extensibility without openness just shifts the bottleneck.
If workflows should be transparent, the tool should be too.

But a true easy to use discord alternative is still not there.
