Why Forge?
The only platform that tests your backend against your actual running server.
🌐
Real API Testing
Your actual running server gets tested with a real HTTP client. No mocks, no shortcuts — if it works in production, it passes here.
🛡️
Anti-Cheat Engine
Behavior analysis detects copy-paste, timing anomalies, and suspicious patterns. Your score reflects what you actually built.
