A homelab OS choice is really a default control plane decision: Proxmox fits best when you expect multiple VMs or containers, TrueNAS fits when storage and data services lead the design, and plain Linux fits when you want direct control over a smaller app stack.

That means the better question is not “which homelab OS wins,” but which platform makes your first workloads easier to operate, back up, and expand without unnecessary layers.
This page helps new operators choose the operating system by workload shape and maintenance path so the server starts with the right foundation instead of an oversized abstraction they do not yet need.

FAQ
Is Proxmox overkill for a first homelab?
Not if you want to try lots of things. It can reduce reinstall pain because you can roll back VMs.
Is TrueNAS only for big storage servers?
No. It makes sense even for a small NAS if your priority is reliable file sharing and snapshots.
Can I run Docker on all three options?
Yes, but the experience differs. Plain Linux is most direct. Proxmox usually means Docker inside a VM. TrueNAS has apps with an appliance-like workflow.
Which option is easiest to migrate later?
Plain Linux is often easiest to lift and shift because it uses standard patterns.
