Behest vs Helicone
They log. We operate.
Helicone is an LLM observability platform — it logs requests, tracks costs, and provides analytics. Behest is the AI backend — it handles auth, memory, PII, rate limiting, and security before the LLM ever sees a request.
Helicone
Helicone is an open-source LLM observability platform. It acts as a proxy that logs every request, providing cost analytics, latency tracking, and usage dashboards.
Strong at: Request logging, cost analytics, latency monitoring, usage dashboards, and prompt versioning.
Category: LLM Observability / Analytics
Behest
Behest is the AI backend. One API call gives you auth, memory, PII scrubbing, prompt defense, rate limiting, token budgets, kill switches, and observability — self-hosted in your cloud.
Strong at: Complete AI backend with security, multi-tenant isolation, built-in business logic, and usage tier economics.

The core difference
Helicone tells you what happened after the fact. Behest controls what happens — scrubbing PII, blocking prompt injections, enforcing rate limits, managing memory, and tracking token budgets in real-time, before the LLM processes the request.
