All observability tools simply log traces with no context. Foil reimagines how you deploy and maintain agents by learning your agents behavoir and responsibilities. We call these agent profiles and they evolve as your agent runs. Hallucinations, behavioral drift, loops, grounding failures: caught automatically with context, not just logged. 🎁 Product Hunt Exclusive - 50% off Pro for 3 months with code FOILPH

Foil is an AI agent monitoring platform that watches other AI agents by learning their behavior and building dynamic profiles. Instead of just logging traces, it auto-generates health checks (anchors), detects hallucinations, behavioral drift, prompt injection, PII leakage, and RAG grounding failures in real-time with contextual explanations. Features include natural language search across agents and traces, per-agent dashboards for cost/latency/quality, multimodal support, and a feedback loop that improves accuracy over time. Setup is via `npx @getfoil/wizard` which auto-instruments your project.
