Question 1

Is OmnisRouter a self-hosted alternative to OpenRouter?

Accepted Answer

Partly. OpenRouter is a hosted marketplace: one API key and one bill across a large catalogue of models. OmnisRouter is a proxy you run on your own machine with your own provider keys. It routes each request to the cheapest capable model and attaches a receipt explaining the choice. If you want managed breadth with no infrastructure, OpenRouter is the simpler path. If you want to self-host, keep your own keys and bills, and see and reproduce the routing, OmnisRouter is the fit. You can also run both.

Question 2

Can I use OmnisRouter and OpenRouter together?

Accepted Answer

Yes. OmnisRouter can call OpenRouter as one of its upstream providers, so you keep OpenRouter's catalogue and add a transparent, self-hosted routing layer with per-request receipts on top.

Question 3

Does OpenRouter show why it picked a model?

Accepted Answer

OpenRouter's automatic selection reports which model answered, but the selection logic is a hosted service you do not run or inspect. OmnisRouter ships the routing model in the open, stamps every decision with the model version that made it, and returns the chosen model, confidence, ranked alternatives and estimated saving on each response.
