Voiden is an offline-first, git-native API tool built on Markdown Voiden is an API client we have been building that takes a different approach from most existing tools.
It didn’t start with the idea of “building a better Postman”.
A bit of background. Over time, API tooling has become heavyweight: cloud dependencies for local work, forced accounts, proprietary formats, and workflows that break the moment you are offline. On top of that, time wasted on fixing API specs that don’t match the code, docs in separate random tools, tests also separate and an overall governance mess. Not to mention collaboration.
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.
- Plain text files: specs, tests, and documentation live together in Markdown
- A programmable interface instead of static forms: requests are composed from reusable blocks (endpoints, headers, auth, params, bodies, etc.) that you can structure the way you want
- Plugin system for extending functionality rather than bloating the core with new features Some of our core plugins include gRPC,GraphQL,WebSockets,etc…
We have just also updated our docs to welcome community plugins, so teams can extend the tool for their own workflows or integrations. https://docs.voiden.md/docs/plugins/build-a-plugin
We opensourced Voiden because extensibility without openness just shifts the bottleneck. If (API) workflows should be transparent, the tools should be too.
Welcome to try out and share feedback- happy to chat with everyone.
Strong opinions are encouraged. :)

This looks interesting, but I don't particularly want another client app for this when we can "just use curl" and have that in files (already very git-friendly)?
This will not help many, but I've found a good way that helps me and my team, since we're all in VSCode most of the time anyway. The extension "REST client" lets us write HTTP calls directly in a file and run them from there, with some basic variables and support for different kinds of authentication scheme and environment variables. It has replaced POSTman and Bruno for us: https://marketplace.visualstudio.com/items?itemName=humao.rest-client
If you're not already using a vscode based IDE this won't help you at all, sure. But, if you are - this lets you write up sequences of requests in a (still manual, but quite quick) file to test APIs and play with them. Highly recommended!
