Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Server Components, streaming, and the App Router represent the future of React. The Vercel deployment experience is unmatched.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Some complexity with the App Router learning curve, but it's the most complete full-stack React framework.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“Next.js defines how modern web apps are built. Server Components and AI SDK integration make it the platform for AI web apps.”
