Why Eaon
A gateway that stays
A gateway that stays
out of the way
The boring infrastructure work — keys, retries, health checks — already done.
Multi-provider routing
One request fans out across backends. Eaon holds the provider keys so you don't juggle five dashboards.
Automatic failover
When a route errors or times out, Eaon retries the next provider before the failure ever reaches your app.
Streaming built in
Server-sent events on every chat model, so tokens land in your UI the moment they're generated.
Live model health
A background monitor tracks every route and flags degraded models before you hit them.
Quick start

in one call
No SDK to install and nothing to configure. Point your existing OpenAI client at Eaon and every model in the catalog is reachable.
