Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“React-like syntax with true reactivity and no Virtual DOM overhead. The performance benchmarks speak for themselves.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Impressive technology but tiny ecosystem. For production apps, React or Svelte have better library support.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“SolidJS's reactivity model is influencing the entire framework ecosystem. The ideas matter even if adoption is niche.”
