What is Gentrace?

Editorial review
Gentrace was an AI observability platform designed to help developers evaluate and monitor their Large Language Model (LLM) applications. It provided tools to track LLM performance, identify issues, and ensure the reliability of AI-powered features. While the commercial service has ceased operations, its core technology is now available as an open-source project on GitHub under the MIT license. This open-source release allows developers to self-host and utilize the evaluation and observability capabilities that Gentrace previously offered as a managed service. It is ideal for teams building with LLMs who require robust testing, monitoring, and debugging tools to maintain high-quality AI outputs and understand how their models are performing in real-world scenarios.
