About

TruLayer is the reliability platform for production AI agents. Three things, together, that you can't get from any single tool today: → Trace every step. Every LLM call, tool invocation, and retrieval hop across multi-agent workflows — captured automatically. → Score every output inline. 25 pre-built LLM evaluators (hallucination, faithfulness, PII leakage, tool-call correctness, and more) run against every span as it arrives. → Act on failures automatically. When an eval rule fires, TruLayer can retry with a fallback model, modify the prompt, or trigger a custom action — before your user sees the broken response. Instrumentation is two lines. Wrap your existing OpenAI, Anthropic, LangChain, LangGraph, Vercel AI SDK, CrewAI, or LlamaIndex client.

TruLayer - Tracing, evals, and a control loop for production LLMs

TruLayer is an AI reliability platform for teams shipping LLMs to production. Tracing — OTLP-native plus SDKs for OpenAI, Anthropic, LangChain, Vercel AI SDK, CrewAI, and 11 others. Evals — 25 LLM-judge evaluators inline: hallucination, faithfulness, tool-call correctness, PII, citation density. Control loop (new in v0.1) — eval fires → cluster → prompt diff → A/B → auto-ship → auto-rollback on regression. HITL gate at any step. Free tier: 1M spans/month, no card.
