Test the gateway behavior you need
PRISMA AIRS AI Gateway documents conditional routing, retries, caching and circuit breakers. Helicone documents provider routing and automatic fallbacks. Test your actual providers and failure conditions; this comparison makes no latency or cost ranking.
Follow the interaction beyond one request
Helicone sessions group requests into agent flows. PRISMA AIRS includes traces, metadata and feedback. Lunary gives application reviewers chat replay with message feedback and linked agent runs. That review experience is worth a separate pilot.
Choose around the unresolved problem
If provider failures are the issue, validate gateway recovery. If answers are wrong despite successful calls, try Lunary with the affected conversation and a prompt revision. Preserve the gateway policies your application relies on during that evaluation.
