OmniRoute adds one local gateway for many AI model providers

OmniRoute is a self-hosted gateway that lets agent tools call many AI providers through one address. It uses an OpenAI-compatible format, so existing tools can point to one endpoint such as `localhost:20128/v1` without major rewrites. It says it supports 237 providers, with more than 90 free routes.

Its main feature is automatic fallback: if one provider fails, returns a server error, or hits a rate limit, the request can move to the next model in a prepared ladder. That ladder can start with a subscription, then API keys, then cheaper models, then free options. OmniRoute also adds a compression step for long tool output such as code diffs, test logs, and build logs, aiming to cut token use by 60% to 90%.

It includes 17 routing methods, including priority, weighted, round-robin, and cost-based routing, plus safeguards for failing providers, keys, and models. The project is open source under the MIT license and is meant to run on your own machine or server.
