OpenRouter
Gateways & routersA hosted marketplace and router that exposes hundreds of models behind one API and one bill.
OpenRouter is a single endpoint to a huge range of models from many providers. One API key, one bill, and automatic routing — including failover when a provider is down or rate-limited.
It removes the friction of holding accounts and keys with every vendor, which makes comparing models or hot-swapping them genuinely easy.
Where it's ideally used
Best when you want fast access to many models — to evaluate or switch freely — without setting up an account per provider.
Where it doesn't fit
Adds a hosted third party to the data path, which is a problem when traffic must stay within your own contracts and perimeter.
