Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Build admin panels in hours instead of weeks. SQL queries, API connections, and components just work together.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“For internal tools that don't need to be beautiful, Retool eliminates weeks of dev time. Genuinely useful.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“AI-generated internal tools will commoditize this space, but Retool's head start and enterprise adoption provide a moat.”
