In simple English
This is an app for building and testing web requests. You write your API calls inside plain text files. It stores everything on your computer, so you do not need an account or internet cloud sync. You share your work with your team using Git version control. It is free to download and use.
What it is
Voiden is an offline-first API client built with Electron (a framework for desktop apps using web technologies) and TypeScript. It stores collections as executable Markdown files that combine documentation, test assertions, and request blocks in one place.
What it is good for
Developers who want an API client that stays entirely local, avoids account logins, and lets them commit requests directly to a Git repository.
- Works completely offline with no account login required.
- Stores requests in plain Markdown files that are easy to version control.
- Supports REST, GraphQL, gRPC, and WebSockets through plugins.
- Built on Electron, so it uses more RAM than native tools.
- Requires manual setup if you want to build it from source code.
- Windows users may see a SmartScreen security warning on first install.
