Secure Integrations, Zero Backend
No API Keys in Browser
Keys stay on our edge. Your frontend calls a secure bridge; we inject secrets server-side so they never touch the client.
Built-in Rate Limiting
Protect against abuse and traffic spikes. Set limits per user or per key without writing backend logic.
Server-Side Header Injection
We add Authorization and other headers on the server. Browsers only see your domain; provider keys stay hidden.
