Reviewer scorecard
“The best GraphQL server for Node.js. Envelop plugin system and multi-runtime support (Bun, Deno, Workers).”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“If you're building a GraphQL API in Node.js, Yoga with Envelop plugins is the most maintainable approach.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“GraphQL servers are mature technology. Innovation has moved to the client and tooling layer.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
