A blogger’s report describes turning a $10 OpenStick into a low-power, passively cooled Debian homelab. The device runs several lightweight services, including DNS filtering, monitoring, an RSS reader and a bookmark archive, though the setup’s exact power use, reliability and purchase availability are not established in the report.
A blogger identified as Bosscher has described using a $10 OpenStick as a small Debian home server, hosting tools for DNS filtering, service monitoring, RSS reading and archived bookmarks. The report offers a practical example of what a low-cost device with limited memory can run, while reflecting one user’s experience rather than a controlled performance test.
According to Bosscher’s account, the OpenStick cost $10 including shipping and has 512 MB of RAM, four 1 GHz ARM Cortex-A53 cores, 4 GB of eMMC storage, Wi-Fi, a cellular modem and GPS. The author says around 450 MB of RAM is usable. The device is passively cooled, which the report describes as silent. After an installation process the author calls involved, it runs Debian, with systemd for services and scheduling and Podman for containers.
The listed software includes AdGuard Home for DNS-based domain blocking, CastSponsorSkip for skipping sponsorship segments on Google Cast devices, and Zeroclaw, an AI agent harness. Bosscher says their AdGuard setup blocks about 60% of DNS queries after adding blocklists; the report does not provide a measurement period or an independent check of that figure. The author says Zeroclaw uses about 3 MB of memory while idle, and is used through Telegram to ask about the server’s logs and disk space.
Other services described include Cloudflare Tunnel for access without exposing ports, Beszel for resource graphs and alerts, Dozzle for viewing Podman logs, Gatus for checking whether services respond, Fusion for RSS feeds, and Shiori for managing and archiving bookmarks. The author gives estimated memory use for several programs, including about 20 MB for Beszel, 10 MB for Gatus and 22 MB for Fusion. These are figures from the report, not independently measured benchmarks.
What a Small Server Can Host
The account shows how a modest single-board device can support a useful collection of personal services when the software is selected for low resource use. For readers considering self-hosting, the setup offers a concrete alternative to running a larger server or a full monitoring stack: several separate functions can share one small Debian machine.
That comes with clear limits. The OpenStick has 512 MB of RAM and 4 GB of storage, so it is not presented as a general-purpose replacement for a desktop or a high-capacity server. The article does not give sustained CPU or power measurements, uptime data, or performance under heavy traffic. Its value is instead the combination of low reported purchase cost, silent operation and a collection of lightweight services.
The security choices also matter. Bosscher says the Zeroclaw agent has access to the OpenStick itself, effectively giving it a root shell, but no access beyond that device. The author considers the limited scope an acceptable risk. That is a personal judgment, not a general security recommendation; giving an automated agent privileged access can carry risks even when the system is isolated.

From Novelty Gadget to Debian Host
Bosscher says the device was bought on a whim because it seemed like an interesting piece of hardware. The author frames the OpenStick as a low-cost way to start self-hosting, rather than as a high-performance machine. Debian provides the operating system environment for the services, while Podman runs containers and systemd handles service management.
The software choices reflect the device’s tight memory budget. Bosscher says a previous deployment of OpenClaw on a Kubernetes cluster used more than 1 GB of memory and caused update and workflow problems. The author chose Zeroclaw instead, citing its documentation, active community and reported low idle memory use. They also mention Picoclaw and Nullclaw as alternatives, but do not offer a comparative test.
The report includes a caution about AdGuard Home: Bosscher runs a personal fork intended to handle large blocklists efficiently, but advises readers against running binaries from unknown sources. The author points readers toward the official version, saying it can work with smaller blocklists. A DNS blocker can prevent some domain requests, but Bosscher notes that it cannot replace a firewall or block every unwanted connection.
“For 10 dollars you basically get a home server with minimal power usage and zero noise!”
— Bosscher, the author of the report
Limits of the One-Device Account
The report is a single user’s account. It does not establish whether the OpenStick remains available at the stated price, how difficult installation will be for other users, or how the device performs over long periods. No independent tests of the listed memory figures, the claimed DNS-blocking share, uptime or energy consumption are provided.
It is also unclear how the services behave under concurrent use, how much storage remains after Debian and the applications are installed, and whether the setup includes backups or a recovery plan. Bosscher describes using Cloudflare Tunnel but does not detail the full network configuration or provide an independent assessment of the privacy trade-offs. The account’s security judgments and reported results should be read as the author’s experience.
The Setup’s Next Reported Change
Bosscher says they have submitted a contribution intended to add rich message support for Telegram to a future Zeroclaw version and points readers to the contribution’s tracking page. The author describes that release as expected, not confirmed, so its timing and inclusion remain uncertain.
The report does not announce a broader product launch, new benchmark or planned hardware test. For now, the next development to watch is whether that Zeroclaw feature appears in a release and whether Bosscher updates the account with further details about the OpenStick’s operation. Readers considering a similar setup would need to check current device availability, software documentation and security requirements before deploying services.
Key Questions
What is the OpenStick homelab?
It is Bosscher’s Debian-based home server built on an OpenStick bought for $10 including shipping. The device is reported to have 512 MB of RAM, four 1 GHz ARM Cortex-A53 cores and 4 GB of eMMC storage.
Which services does the author run on it?
The report lists tools for DNS filtering, Cast sponsorship skipping, monitoring, container logs, uptime checks, RSS feeds and bookmark archiving, along with a Telegram-connected AI agent. The author gives approximate memory figures for some, but not every service.
Does the setup block 60% of all internet traffic?
No. Bosscher says the AdGuard Home configuration blocks about 60% of DNS queries after blocklists were added. That is not a claim about all internet traffic, and the report does not specify the measurement window or independently verify the figure.
Is this configuration suitable for every user?
The report does not establish that. The device has limited memory and storage, and installation is described as involved. Bosscher also grants an AI agent root-level access to the OpenStick, a personal risk decision that readers should evaluate separately.
What is expected next?
Bosscher says a future Zeroclaw version may include rich Telegram message support through a contribution they submitted. The report does not give a release date or confirm that the feature has shipped.
