💡 Our Take
Choose Cloudflare AI Gateway if you want an edge-deployed proxy with native fallback, DLP, and tight integration into Workers AI / Vectorize — and especially if you are already on Cloudflare. Choose Helicone if you want a more product-focused observability dashboard with richer prompt-management UI, custom properties, and a workflow geared toward LLM developers rather than infrastructure teams.
Cloudflare AI Gateway - Pros & Cons
Pros
- ✓Free on all Cloudflare plans including the no-cost tier — no credit card required to start
- ✓Supports 20+ AI providers (OpenAI, Anthropic, Google, Bedrock, Workers AI, etc.) through one unified endpoint
- ✓Single-line integration — only the API endpoint URL needs to change, no SDK rewrites
- ✓Edge-deployed on Cloudflare's global network with sub-10ms cached response times
- ✓Native integration with Cloudflare Workers AI, Vectorize, and R2 for full-stack AI infrastructure
- ✓Beta features like DLP, Guardrails, and Dynamic Routing extend beyond simple proxying into AI safety and traffic management
Cons
- ✗Adds an additional infrastructure dependency and proxy hop to every AI request
- ✗Lacks the deep prompt versioning, evaluation, and dataset tooling of dedicated LLMOps platforms like LangSmith or Langfuse
- ✗Many advanced features (Dynamic Routing, DLP, Guardrails, WebSockets, BYOK) are still in beta and may change
- ✗Best value is realized only if you are already in or willing to adopt the Cloudflare ecosystem
- ✗Configuration of dynamic routing JSON and fallback policies has a learning curve for sophisticated multi-provider setups
Helicone - Pros & Cons
Pros
- ✓Proxy-based integration requires only a base URL change — genuinely zero-code setup for OpenAI and Anthropic users in under 5 minutes
- ✓Real-time cost analytics with per-user, per-feature, and per-model breakdowns are best-in-class for LLM spend management
- ✓Gateway-level request caching can reduce API costs 20-50% for applications with repetitive queries
- ✓Open-source under MIT license with self-hosted Docker option gives full data control for security-conscious teams
- ✓Built-in rate limiting and retry logic at the proxy layer eliminates operational code from your application
- ✓Free tier includes 10,000 requests/month with full feature access — generous compared to most observability platforms in our directory
Cons
- ✗Proxy architecture adds 20-50ms latency per request, which compounds in latency-sensitive agent loops with many sequential calls
- ✗Individual request-level visibility doesn't capture multi-step agent workflows or retrieval pipeline context natively
- ✗Session and trace grouping features are less mature than Langfuse or LangSmith's dedicated tracing capabilities
- ✗Free tier limited to 10,000 requests/month — production applications will quickly need the $20/seat/month Pro plan
- ✗Self-hosted deployment is operationally complex, requiring Supabase and ClickHouse infrastructure to run in production
