Backmesh
Open-source gateway that hides LLM API keys, enforces per-user rate limits and logs usage; self-host free or hosted from $10/mo.
What it does
Backmesh is an open-source backend that acts as an API gatekeeper so client apps can call LLM APIs (like OpenAI) directly without exposing secret keys. It verifies requests with JWTs from your auth provider, enforces per-user rate limits and protects sensitive API resources like files and threads. It also instruments all LLM calls for usage analytics, and can be self-hosted or used as a hosted service.
