Helicone - Pros & Cons
Pros
- ✓Proxy-based integration requires only a base URL change — genuinely zero-code setup for OpenAI and Anthropic users
- ✓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 with self-hosted 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
Cons
- ✗Proxy architecture adds 20-50ms latency per request, which compounds in latency-sensitive agent loops
- ✗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
