Checkly
Checkly review on AInexfinder — freemium AI tool for Coding & Development. Features, pricing notes, and alternatives.
- Code-first workflow fits engineering practices
- Realistic Playwright-powered checks
- AI-assisted monitor creation and diagnosis
- Playwright-based synthetic browser checks
- Code-first model is less approachable for non-developers
- Costs scale with check frequency and volume
- May be more specialized than an all-in-one suite
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
