Voiden is an offline-first API client for developers, Testers and Technical Writers who want their API work to feel like code—not a SaaS dashboard.
Voiden lets you build, test, and link API requests like reusable blocks, comment on JSON or XML, preview responses (even PDFs or videos), and manage environments, themes, and scripts. The best part is that Voiden enables all this without ever needing the cloud. Voiden is your API lab: fast, transparent, versionable, and unapologetically opinionated.
No accounts, no sync, no cloud required.
