// EDITOR'S TAKE
MinIO is the closest drop-in, compatible enough that most SDK code needs only an endpoint change, though its licensing and feature gating have pushed some teams to look elsewhere. Garage is the better fit for small self-hosted clusters spread across a few locations, and Ceph only earns its complexity if you need block and file storage from the same cluster.
