Dokku vs Umbrel
A side-by-side editorial comparison of Dokku and Umbrel — release velocity, themes, recent moves, and the top alternatives to consider.
Dokku vs Umbrel: at a glance
What is Dokku?
Dokku's autumn patches swap new features for safer deploys and stricter validation.
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.
What is Umbrel?
umbrelOS 2.0 went final in September; 2.0.1 is a kernel patch with a Raspberry Pi stopgap.
umbrelOS 2.0 shipped on September 22 after two betas, bringing Photos, iPhone and Mac apps, Machines, multiple users, an MCP server, Storage Manager with FailSafe RAID, cloud downloads, GPU acceleration and automatic HTTPS. Beta 2 added agents that can create and use Machines while the owner watches. 2.0.1 on November 1 fixes CVE-2026-98432 with a patched kernel on x86 devices; Raspberry Pi has no fixed kernel yet, so umbrelOS blocks the traffic needed to trigger it.

Dokku
5.0INFRA · APIS
Dokku's autumn patches swap new features for safer deploys and stricter validation.
◆ Current state
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.
◆ Where it's heading
The August k3s parity push has given way to a hardening pass through commands that used to fail quietly. A second thread makes configuration declarative: storage mounts, scheduler-k3s metadata and chart overrides each gained a whole-set form, which suits automation tools more than people at a terminal. Machine use of the CLI remains the through-line.
◆ Prediction
Expect the whole-set form to reach more properties, since three subsystems have now gained it. Patch releases should stay frequent, and the notes give no sign of a move past the 0.38 line.
Umbrel
2.5INFRA · APIS
umbrelOS 2.0 went final in September; 2.0.1 is a kernel patch with a Raspberry Pi stopgap.
◆ Current state
umbrelOS 2.0 shipped on September 22 after two betas, bringing Photos, iPhone and Mac apps, Machines, multiple users, an MCP server, Storage Manager with FailSafe RAID, cloud downloads, GPU acceleration and automatic HTTPS. Beta 2 added agents that can create and use Machines while the owner watches. 2.0.1 on November 1 fixes CVE-2026-98432 with a patched kernel on x86 devices; Raspberry Pi has no fixed kernel yet, so umbrelOS blocks the traffic needed to trigger it.
◆ Where it's heading
Umbrel has moved from a server you visit to one that agents and phones use directly: per-agent tokens, background camera-roll backup and Finder integration all reduce the need to open the web interface. The first release after 2.0 is security maintenance, and that maintenance now covers a wider surface, from HEIC thumbnails to trusted certificate authorities.
◆ Prediction
Google Drive download, flagged as coming soon in the 2.0 notes, is the clearest next feature. A proper kernel fix for Raspberry Pi should replace the traffic block in a following update.
