Galileo
Evaluation and observability for LLM apps and agents Category: Coding & Development.
- Broad library of research-backed metrics
- Bridges offline testing and production guardrails
- Enterprise-friendly deployment flexibility
- 20+ pre-built evaluations for RAG, agents, and safety
- Learning curve for teams new to LLM evaluation
- Full capabilities are priced for organizations
- There is a short learning curve for new users
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
