Hi there! Kyle here, the other half of Depot. This is correct, we have a self-hosted data plane model that larger enterprises can use if they want full control over the builders + build cache.

In that deployment model, the Depot control plane passes changes to make in the customers environment via a small agent they run in their account. Here is some docs we put together for anyone that wants to go into a bit more of the details: https://depot.dev/docs/self-hosted/architecture
