💡 Our Take
Choose Cloudflare AI Gateway if you need infrastructure-grade reliability features (caching, fallback, rate limiting) and prefer not to self-host. Choose Langfuse if you want open-source LLMOps with self-hostable traces, evals, prompt versioning, and a generous free cloud tier — it complements rather than replaces an edge proxy, so combining the two is a common pattern.
