Failproof AI

Failproof AI is a monitoring and policy enforcement platform for teams building autonomous agents. It captures every prompt, tool call, and result across 12 agent harnesses including Claude Code, Codex, Cursor, and Gemini, then applies customizable policies to prevent failures in real time. The tool detects common failure patterns like infinite loops, hallucinations, context drift, and dangerous actions, blocking problematic calls before execution.

Designed for developers and researchers who need production-grade reliability, Failproof provides live tracing, session history, and audit clustering to surface recurring issues. It includes 40 built-in policies, runs locally with zero latency, and offers a free tier via npm. The project is open source and supports 12 coding CLIs and chat gateways.
