Omniagent looks quite similar to OpenRouter (https://openrouter.ai/)

Omnigent and OpenRouter are different in the sense that OpenRouter is where you can go to call the actual model but Omnigent is intended to be the place where you go describe the high level task to be done, and work is farmed out to various harnesses and models. Those sandboxes can themselves be using OpenRouter for capacity!

We're calling the layer coordinating harnesses "meta-harness'

Omnigent seems to compete more against Orca https://github.com/stablyai/orca They both went to be the Agent IDE layer, where you come with your tasks and everything is taken care of. I've been using Orca for a handful of tasks and have been largely enjoying it. My default barebones workflow is ghostty + zmx on ssh connections.

These tools casually like to claim they are orchestrators, but unfortunately, none of them are.
