Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Fastest editor I've ever used. Native performance, real-time collab, and the AI integration is well-designed.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Fast but the extension ecosystem is small compared to VS Code. You'll miss plugins you depend on.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“The next-gen editor built for AI and collaboration. Rust performance advantage over Electron is real.”
