About the tool

Open-source evaluation and tracing for LLM apps and agents.

TruLens instruments every span of agent execution — latency, inputs, outputs, tokens, and cost — and scores runs with benchmark-tested feedback functions covering RAG quality, safety, and agent behavior. Originally from TruEra, it is now maintained in open source under Snowflake's stewardship.
