Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Remote caching and affected-only testing save enormous CI time. The project graph visualization is invaluable for large repos.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“If you have a monorepo with more than 5 projects, Nx pays for itself in CI time savings on day one.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“Monorepos are winning. Nx and Turborepo are making them practical at any scale.”
