A report by Bosscher describes using a $10 OpenStick as a low-power homelab running Debian and a set of lightweight self-hosted services. The device has 512 MB of RAM and 4 GB of storage, so the setup relies on small applications for DNS filtering, monitoring, RSS reading, bookmarks and AI-assisted server checks.
In a report on a $10 OpenStick homelab, blogger Bosscher describes running Debian-based services for DNS filtering, server monitoring, RSS reading and more on a small device with 512 MB of RAM and 4 GB of eMMC storage. The example shows how low-cost, low-power hardware can host personal services, while also highlighting the limits and security trade-offs of running them on a constrained device.
Bosscher says the OpenStick cost $10, including shipping. The device has four 1 GHz ARM Cortex-A53 cores, about 450 MB of usable memory, 4 GB of eMMC flash, Wi-Fi, a 4G modem and GPS. It is passively cooled and has one programmable LED. Bosscher describes the installation as involved; once installed, the device runs Debian, including systemd and Podman.
The services are selected for their relatively small memory use. Bosscher reports using AdGuard Home for DNS-level domain blocking, and says about 60% of DNS queries are blocked after adding several blocklists. That figure is the author’s observation; the report does not provide a measurement period or a breakdown of what was blocked. Bosscher cautions that DNS filtering cannot block every unwanted request and says the author’s own AdGuard fork handles large blocklists efficiently. The report advises caution about running binaries from unknown developers and points readers to the official version as an alternative.
Other tools include CastSponsorSkip for skipping sponsorships and sometimes ads on Google Cast devices; Zeroclaw, an AI agent harness; Cloudflare Tunnel for reaching services without exposing ports; Beszel for resource graphs and alerts; Dozzle for viewing Podman logs; and Gatus for service checks. Bosscher also reports running Fusion, an RSS reader using about 22 MB of RAM, and Shiori, a bookmark manager that archives pages. Memory figures in the report are the author’s estimates and describe individual software components, not a benchmark of the full system running all services together.
Small Hardware, Useful Services
The report offers a practical example for readers considering self-hosting on a budget: a small computer can run several everyday services without the power use or noise of a larger server, according to Bosscher. The software choices also show how lightweight alternatives can replace parts of a larger monitoring or hosting setup when a user does not need extensive features.
There are limits to that example. The OpenStick’s 512 MB of RAM and 4 GB of storage leave little room for demanding workloads, and the report does not include power consumption measurements, reliability testing, or a full-system memory and performance profile. The setup is best read as one user’s configuration, not a guarantee that every listed service will run well together on every OpenStick.
Security choices matter as much as hardware. Bosscher says Zeroclaw has access to the OpenStick that is effectively equivalent to a root shell, but not to anything beyond the device. The report also describes using Cloudflare Tunnel and acknowledges a privacy trade-off. Those decisions may suit the author’s needs, but users should weigh access, data handling and exposure before copying the configuration.

From Novelty Device to Debian Server
Bosscher says the purchase began as an impulse buy because the device seemed like an interesting hardware novelty. The author later treated it as an entry point to self-hosting, noting that Debian provides familiar Linux service management through systemd and container support through Podman. The report does not give a publication date, installation guide or complete hardware model details, so the configuration cannot be independently reproduced from the supplied account alone.
The software list reflects a preference for smaller services rather than a broad, centralized monitoring stack. Bosscher says a previous Kubernetes setup with Grafana felt powerful but excessive for this use, and contrasts Zeroclaw with OpenClaw, which the author says used more than 1 GB of memory and was frustrating to maintain. These are personal comparisons, not controlled tests. Bosscher also considered Picoclaw and Nullclaw before choosing Zeroclaw, citing its documentation and community activity.
“For 10 dollars you basically get a home server with minimal power usage and zero noise!”
— Bosscher, the report’s author
Limits of the Reported Setup
The account does not state when the report was published, the OpenStick’s exact model, or whether all listed services were running simultaneously during the memory estimates. It also gives no independent measurements of power use, uptime, network performance, total memory pressure or performance under load. The reported 60% DNS blocking rate has no stated time window or comparison baseline.
Some details are explicitly personal judgments: Bosscher’s assessment of software reliability, security defaults and privacy trade-offs is not an independent audit. The author says Zeroclaw has access equivalent to a root shell on the OpenStick; the exact safeguards and the consequences of a compromise are not detailed. The report does not establish that the same configuration would be safe or suitable for other users.
Bosscher says a future Zeroclaw version may add rich-message support for Telegram, and points to a pull request the author contributed. The report does not provide a release date or say whether that change has been accepted. Bosscher’s described next step is to keep using the small server to check logs and disk space through Telegram; no broader product or hardware announcement is reported.
Key Questions
What hardware does the $10 OpenStick have?
Bosscher lists four 1 GHz ARM Cortex-A53 cores, 512 MB of RAM (about 450 MB usable), 4 GB of eMMC flash, Wi-Fi, a 4G modem, GPS and passive cooling. The report does not identify the exact model or say whether the price is still available.
Which services does Bosscher run on it?
The report lists AdGuard Home, CastSponsorSkip, Zeroclaw, Cloudflare Tunnel, Beszel, Dozzle, Gatus, Fusion and Shiori. It does not give a complete resource profile for all services running together.
Does AdGuard Home block 60% of all internet traffic?
No. Bosscher says about 60% of DNS queries were blocked after adding several blocklists. The report does not state the measurement period, and DNS filtering does not block every unwanted connection.
Is the setup a security recommendation?
No. It is one user’s account. Bosscher describes granting Zeroclaw access equivalent to a root shell on the device and notes privacy trade-offs around Cloudflare Tunnel. Readers should review software sources, permissions and data handling before adopting a similar setup.
