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
Momentic
Momentic is an agentic end-to-end testing platform where AI writes tests as plain-English YAML, runs them across web, iOS and Android, and self-heals them when the UI changes, with an autonomous bug-bashing agent, an MCP server and CI integration.
- Tackles test maintenance, the real QA pain
- Readable, reviewable tests instead of brittle scripts
- Self-heal-versus-flag reduces false alarms
- Autonomous bug-bashing before release
- Overkill for tiny, stable test suites
- Usage-based cost scales with how much you run
- Headline stats are vendor-stated
