Reviewer scorecard
“Elegant simplicity. For CRUD apps and content sites, htmx eliminates the need for a JavaScript framework entirely.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Not for every use case, but for the apps it fits, it dramatically reduces complexity. The meme game is also S-tier.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“The pendulum swinging back toward server-rendered HTML is real. htmx is leading the hypermedia renaissance.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
