TrueNAS 26 isn't trying to be Proxmox, but it's getting awfully close for homelab users

TrueNAS 26 (beta) introduces fully supported LXC containers (no longer experimental), high availability failover for containers, GPU passthrough for Nvidia and other GPUs, USB/PCIe device passthrough, and a refined web UI. These additions significantly close the gap between TrueNAS and Proxmox for homelab users who previously needed both platforms. LXC containers share the host kernel for lower overhead than VMs, making them ideal for resource-constrained hardware. Container HA requires static IPs and is currently scoped to paired HA controllers rather than multi-node clusters. Other changes include a new annual release cadence, OpenZFS 2.4 with Hybrid Pools, Linux Kernel 6.18 LTS, Ransomware Detection, and a WebShare UI. While TrueNAS still lags behind Proxmox in multi-node clustering and VM tooling maturity, it now makes a compelling case as a single-box solution for both storage and containerized workloads.
