Helicone vs Respan

Our take

Pick Helicone if you're on a team who will change one baseURL and then live in the request table. Pick Respan if you're on a team who will stay on Free at $0 (100k logs, 1k scores) while they open a first All logs, then Team at $199/month yearly when they need unlimited prompts or a SOC 2 report. Skip Helicone if you're orgs that already standardized on LangSmith and will not move the proxy (LangSmith).
