About Latitude

Latitude is an open source observability platform for AI agents, written in TypeScript and released under the MIT license. It lives in the AI and machine learning infrastructure ecosystem, where it targets the specific problem of agents that fail in production without a clear path from failure to fix. The project describes itself as tooling that makes AI agents self healing, and its repository topics — agent monitoring, agent observability, llm error tracing, llm observability, ai error monitor — place it squarely in the LLM observability space.
