Reviewer scorecard
“Free tier with no restrictions is remarkable. Completion quality rivals Copilot for most languages.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Hard to argue with free. The enterprise features and Windsurf IDE show they have a real business model beyond the free tier.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Giving away code completion to win IDE market share with Windsurf is a smart long-term play.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
