A side-by-side editorial comparison of Umbrel and OctoPrint — release velocity, themes, recent moves, and the top alternatives to consider.
umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.
umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.
OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.
The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

Umbrel is building a desktop metaphor on top of a personal server: 1.5 added encrypted backups, file history and GPU acceleration, and 1.7 adds shortcuts, a text editor and network shares. At the same time, shipping a full operating system means inheriting the kernel's vulnerability schedule, and two of the four releases in this window exist solely because of it. That is the ongoing cost of the model.
Expect the Files and home screen surfaces to keep absorbing desktop functionality, since that is where the last two feature releases have concentrated. Also expect the kernel CVE cadence to keep interrupting it — the two May releases arrived a week apart and neither was planned.

Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.
Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.
Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
