Helicone pros and cons
Extremely easy integration via a one-line base-URL swap
Open source under Apache 2.0 and free to self-host
Tiny Docker image that runs almost anywhere
Gateway features like caching, failover, and rate limiting cut cost and improve reliability
Product is in maintenance mode after the Mintlify acquisition, with no roadmap
Long-term hosted-service viability is uncertain and migration may be needed
Usage-based overages mean the Pro price is a floor, not a cap
Galileo pros and cons
Purpose-built Luna evaluation models (fast, cheaper than LLM-judge)
20+ research-backed metrics
Covers evaluation, observability, and guardrails
Polished console with minimal setup
Pro at $100/month may be steep for small teams
Free plan lacks RBAC and advanced analytics
Managed platform hosts your evaluation data (unless enterprise self-host)
