A blog post by Bosscher describes using a $10 OpenStick as a low-power Debian home server for a collection of lightweight services. The setup includes DNS filtering, monitoring, RSS, bookmarks and a Telegram-connected AI agent; the post reports the device has 512 MB of RAM and 4 GB of storage.
In a report on a personal homelab, blogger Bosscher describes running a set of self-hosted services on a $10 OpenStick, a small, passively cooled device with 512 MB of RAM and 4 GB of eMMC storage. The example shows how modest hardware can handle selected server tasks, while also making clear that the setup depends on lightweight software and careful choices about what to run.
Bosscher says the OpenStick has four 1 GHz ARM Cortex-A53 cores, about 450 MB of usable memory, Wi-Fi, a 4G modem and GPS. After an installation process the author describes as involved, it runs Debian, including systemd for managing services and Podman for containers. The device is passively cooled, which the author says makes it silent.
The listed services cover several common home-server needs. AdGuard Home filters domain requests, while Beszel monitors system resources and sends alerts; Gatus checks whether services remain available. Dozzle provides an interface for viewing Podman container logs. Bosscher also runs Fusion for RSS feeds and Shiori to manage and archive bookmarks.
The setup also includes CastSponsorSkip, which the author says skips sponsorships and sometimes ads on Google Cast devices, and Zeroclaw, an AI agent connected through Telegram. Bosscher reports that Zeroclaw uses about 3 MB of memory while idle and is used to check the device’s logs and disk space. These figures and assessments come from the author’s account, not an independent test.
Small Hardware, Practical Home Services
The report offers a concrete example for people interested in self-hosting on a tight budget: a low-cost device can run a useful collection of network and personal services without the power use and noise associated with some larger setups. Its limits are just as relevant. With roughly 450 MB of usable RAM and 4 GB of storage, the OpenStick is not presented as a general-purpose server for heavy workloads.
The service list also illustrates the trade-offs involved in fitting software to constrained hardware. Bosscher says an earlier OpenClaw setup used more than 1 GB of memory and caused problems with updates, while Zeroclaw fits the narrower monitoring task. That comparison is the author’s experience and should not be treated as a controlled benchmark. Readers considering a similar setup should also weigh security: a DNS filter does not replace a firewall, and giving an AI agent shell access carries risk even when its access is limited to one device.

From $10 Gadget to Debian Server
Bosscher says the OpenStick was bought on a whim for $10 including shipping, initially as a novelty. The appeal, in the author’s account, is not raw computing power but the chance to experiment with a quiet, low-power server and self-hosting tools. The article describes Debian as the foundation that makes familiar Linux services and container management available on the device.
The software choices reflect the hardware constraint. Bosscher gives approximate memory figures for several services, including 22 MB for Fusion, about 10–20 MB for Shiori and around 20 MB total for Beszel’s agent and server. The author says a personal fork of AdGuard Home handles large blocklists efficiently, while cautioning readers against running binaries from unfamiliar sources and pointing to the official version as an alternative for smaller lists.
“It uses ~3 MB RSS when idle, covers all the functionality that I need”
— Bosscher, on Zeroclaw
Limits of the Reported Setup
The source is a personal account, not a lab test, and it does not specify how long the services were measured or how their memory use changes under load. The reported 60% blocked DNS queries has no stated measurement window or comparison baseline, so it should be read as an observation from Bosscher’s setup rather than a general result.
The report also does not provide full details about the OpenStick’s exact model, current price, power consumption, network performance in practice or the security configuration used for every service. Bosscher acknowledges that Zeroclaw has what amounts to a root shell on the device, while saying access is limited to the OpenStick. The post does not describe independent security testing or establish whether the setup is suitable for other users’ risk tolerance.
Possible Software and Setup Changes
Bosscher says a future Zeroclaw version may add richer Telegram message support, with the author’s contribution tracked in a pull request. The report does not give a release date or confirm that the feature has shipped. For the homelab itself, the author says Dozzle and Beszel have some overlap and that one might be removed if memory becomes tight.
For readers considering the same approach, the next steps are practical rather than a confirmed product roadmap: check the device and installation requirements, compare memory needs with the services to be hosted, and review software sources and access permissions. The source provides no follow-up benchmark or update on the OpenStick’s long-term reliability.
Key Questions
What is an OpenStick?
In Bosscher’s report, it is a small computing device used as a home server. The author lists 512 MB of RAM, 4 GB of eMMC storage and four 1 GHz ARM Cortex-A53 cores.
Which services does Bosscher run on it?
The reported setup includes AdGuard Home, Beszel, Gatus, Dozzle, Fusion and Shiori, as well as CastSponsorSkip and the Zeroclaw AI agent. The article describes these as the author’s chosen services, not a recommended package for every device.
Can the OpenStick run demanding software?
The report does not test demanding workloads. Its limited memory and storage suggest the setup is aimed at lightweight services; Bosscher says some software they tried previously used more memory than the device could offer.
Does the DNS blocker stop all tracking or malicious traffic?
No. Bosscher explicitly says a DNS blocker cannot block every bad request and that a proper firewall is needed for broader network protection. The reported 60% blocked-query share is specific to the author’s setup, with no measurement period provided.
