Behest vs Open Source Routers
They proxy. We operate.
Open source routers standardize API calls across providers. Behest is a managed AI backend — it handles auth, memory, PII scrubbing, rate limiting, token budgets, and more.
Open Source Routers
Open source routers provide a unified API for calling 100+ LLM providers. You host it, manage it, and build everything else around it.
Strong at: Multi-provider routing, API standardization, model fallback, and budget controls.
Category: Open-source LLM Proxy
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.
Category: AI Backend as a Service
The core difference
Open source routers standardize how you call LLMs. Behest operates the entire backend — handling auth, scrubbing PII, blocking prompt injections, enforcing rate limits, managing memory, and tracking token budgets. Open source routers give you a proxy; Behest gives you a complete, managed AI backend.
