Helicone
Helicone is open-source LLM observability and an AI gateway. It logs and analyses requests across OpenAI, Anthropic, Gemini, Mistral, Groq, Together and OpenRouter, with sessions, user-level tracking, a query language, prompt management, datasets, a playground, rate limits and alerts.
- Covers the failure everyone hits — being unable to reconstruct what an AI feature actually did
- Session view makes multi-call interactions debuggable rather than guessable
- Per-user cost attribution reveals a spend distribution that totals completely hide
- Gateway positioning is what makes caching, routing and rate limiting possible at all
- Gateway mode puts a new dependency in your request path, with latency and availability consequences
- No latency overhead figures are published for that gateway position
- The open-source licence is not stated on the pages we read

- Powerful AI auto-healing reduces flaky tests and maintenance burden
- Unified platform covers UI, mobile, API, performance, and accessibility
- Low-code trainer makes test creation accessible to QA teams
- Low-code end-to-end testing for browser UI, mobile UI, and APIs
- Pricing is sales-led and not published, with no ongoing free tier
- Credit-based cloud run model can get expensive at scale
- Team collaboration tools depend on your plan
