PublicAI Gateway - One key. Every major LLM with auto-failover.

by•
PublicAI Gateway is one endpoint for every major LLM. Bring your own keys and call Claude, GPT, and Gemini through a single API key and dashboard. When a provider rate-limits or goes down, the gateway reroutes to a healthy one automatically, so your app never goes dark. Set hard spend caps per key, see usage across all providers in one place, and stop juggling three accounts. It runs in a confidential computing environment, so your keys and code stay private even from us, and you can verify it.

We built PublicAI Gateway after one of my agents died for the third time in a week because a single provider had a bad day. The idea is simple: one API key in front of Claude, GPT, and Gemini, and when one goes down the gateway quietly reroutes to another so your app stays up. You bring your own provider keys, set spend caps, and see usage across all three in one place. It also runs inside a confidential computing environment, so your keys and code stay private even from us, and you can verify that with remote attestation. Would love your feedback, and happy to answer anything about how the routing and failover work.
