Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“The compiler approach produces smaller, faster output. Svelte 5 runes are elegant. SvelteKit is a joy to use.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Smaller ecosystem than React but the DX is genuinely better. For new projects without React ecosystem needs, it's the best choice.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“Svelte proves that a compiler-first approach to UI frameworks is viable. The ideas are influencing React and Vue.”
