Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Types from server to client with zero code generation. The DX is magical — change a server type, client updates instantly.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“For TypeScript full-stack apps, tRPC eliminates an entire category of bugs. No schemas, no codegen, just types.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“tRPC proved that type-safe APIs don't need schemas or code generation. The idea is being adopted everywhere.”
