Self-Host Weekly (29 August 2025)

Weekly Highlights

Another week, another project gone open-source. Telemetry Harbor – a data storage and visualization platform I wasn't familiar with until a few days ago – announced they're officially making the switch earlier this week. In the accompanying blog post, the team provides some insight into the background behind the decision by citing transparency, data sensitivity, and community as key motivators.

In a move sure to please just about everyone reading this newsletter, they've also committed to a 100% open code base that won't see any functionality locked behind a paywall:

Telemetry Harbor OSS isn't a stripped-down "community edition." It's the same production-grade stack that powers our cloud platform.

But while I always applaud these initiatives, I have to admit – I don't mind enterprise offerings as much as the rest of the community. As someone who religiously monitors project launches for the newsletter each week, I regularly come across a number of deprecated projects as well. And the most commonly cited reason for their discontinuation? A lack of funding.

This is hardly surprising. In last year's user survey, 60% of participants admitted to not having donated to a self-hosted project in the last year. Couple that with enterprise budget cuts and vibe coding, and it's not difficult to understand why open-source isn't always feasible or sustainable.

Occasionally, I receive feedback from readers informing me (as if I wasn't aware) I had featured closed source software or insisting I stop. In most instances, I politely remind them the site is selfh.st, not opensour.ce.

In other unrelated news, the following activity grabbed my attention this week while I wasn't busy planning a mechanical keyboard rebuild after spilling a smoothie on mine (please send keycap recommendations):

• Unraid released the second beta for its v7.2.0 update, which introduces a responsive web UI (yay, mobile), SSO/OIDC login, and built-in API
• Google announced they'll begin requiring developer verification for installed Android apps in 2026 (which is a bummer as I currently use Obtainium to sideload self-hosted companion apps)
• A Redditor 3D printed a companion cube case for their server (and promised to share the STL files in the coming weeks)
• MXroute – a popular hosted e-mail service in the self-hosting community – announced their lifetime plans will now include a $1/year fee in perpetuity to identify users who've abandoned the platform
• Someone patched TrueNAS Scale to run on ARM and Jeff Geerling wasted no time in getting it up-and-running on a Raspberry Pi
• A ton of new *arr-related apps (see new software below)

Happy selfh.st/ing!

Meet CronMaster, a self-hosted web application for managing and scheduling tasks via cron. Built for users allergic to the command line and crontab -e, CronMaster provides a streamlined and minimal interface for uploading and managing a library of scripts with the ability to schedule tasks via cron schedule expressions.

CronMaster can be easily deployed via Docker and comes with some important caveats to be aware of when installing.
