Reviewer scorecard
“Visual regression testing catches bugs that unit tests miss. The Storybook publishing and review workflow is seamless.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Expensive at scale but visual testing ROI is real. Catching UI regressions before production saves time and trust.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Design review directly on PRs is game-changing. No more 'does this match the design?' back and forth.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
