Antigostman brings the power of professional API testing back to your desktop without the heavy browser engine. 100% Offline. No Sign-up. No Cloud Sync. Just you and your code.
We believe tools should respect your resources. Antigostman is built with pure Java Swing, delivering a snappy, responsive experience that uses a fraction of the memory of Electron-based alternatives.

This project was brought to life with the incredible assistance of Google Antigravity 🚀, the agentic AI coding assistant from Google DeepMind.
~95% of Antigostman's base code was collaboratively written with Antigravity, demonstrating the power of human-AI pair programming. From architecture decisions to feature implementation, Antigravity helped transform ideas into production-ready code at remarkable speed.
