LangWatch is an open-source observability and evaluation platform for agents: every model and tool call is stitched into a full trace, then the same test set is rerun after a prompt or workflow change to see whether scores went up or down. Beyond tracing and evals it adds routing and governance, so a team running several agents and coding assistants can watch each application in one place. Self-hostable. 🔗 Docs: https://docs.langwatch.ai | GitHub Stars: 5k+
