I'm using Dokploy, would that be very similar, or quite different?

Uncloud is lower-level. Dokploy seems to be positioning as a PaaS with a web UI using Docker Swarm under the hood for multi-node container management. Uncloud operates at that same layer as Swarm but with a simpler operating model that's friendlier for troubleshooting, WireGuard mesh networking built in, and the ability to connect nodes from different clouds or locations.

No UI yet (planned) so if that's critical, Dokploy is likely a better choice for now.

However, some unique features like building and pushing images directly to your nodes without an external registry give Uncloud a PaaS-like feel, just CLI-first. Really depends on what you're hosting and what you're optimising for.
