A report by Bosscher describes using a $10 OpenStick as a low-power, passively cooled Debian homelab. It runs small services for DNS filtering, monitoring, RSS, bookmarks and Telegram-based server checks, though the account does not independently verify the hardware price, performance or security claims.
Bosscher says a $10 OpenStick is running a collection of self-hosted services, from DNS filtering and server monitoring to an RSS reader and an AI agent. The account presents the small, passively cooled device as an inexpensive way to experiment with home servers, while noting its limited memory and the setup effort required.
According to the report, the OpenStick has 512 MB of RAM, of which about 450 MB is usable, four 1 GHz ARM Cortex-A53 cores, 4 GB of eMMC storage, Wi-Fi and a 4G modem with GPS. Bosscher says the device is passively cooled and silent. The listed price was $10 including shipping, but the source does not provide a purchase date or independent price check.
The device runs Debian, with services managed using systemd and Podman containers. Bosscher lists CastSponsorSkip, AdGuard Home, Zeroclaw, Cloudflare Tunnel, Beszel, Dozzle, Gatus, Fusion and Shiori among the services. Their reported memory footprints are generally modest: for example, about 20 MB for Beszel’s agent and server combined, 22 MB for Fusion, and roughly 10–20 MB for Shiori. These figures are the author’s reported observations, not independently tested benchmarks.
The services cover distinct jobs. AdGuard Home filters domain requests, while Beszel tracks host resource use and can send alerts; Gatus checks whether services are responding. Dozzle provides a web interface for container logs. Fusion supplies RSS reading, and Shiori manages bookmarks and archives pages. Bosscher also uses Zeroclaw through Telegram to ask about logs and disk space, granting it access to the OpenStick but, the report says, no access beyond that device.
Small Hardware, Useful Services
The report illustrates how a modest device can support a personal, always-on server when its workloads are chosen around strict memory and storage limits. For readers interested in self-hosting, the examples offer a concrete alternative to running a larger server or a full monitoring stack: a handful of focused services can cover home network filtering, uptime checks, feeds and saved pages.
It is also a practical account of trade-offs, not a claim that the device can replace a general-purpose server. The author describes the hardware as limited and says installation takes some effort. A 512 MB system leaves little room for memory-heavy applications, while the small eMMC capacity constrains storage. The reported setup’s value is its low cost and low power use, rather than high performance or broad capacity.
Security and availability also depend on configuration. Bosscher says Cloudflare Tunnel allows remote access without exposing ports, and acknowledges a privacy trade-off in routing traffic through a third-party service. DNS filtering can block some domains but is not a substitute for a firewall. Giving an AI agent shell-level access to a device creates risk even if that device is isolated from the rest of a home network.

How the OpenStick Is Set Up
Bosscher describes the OpenStick as a novelty purchase that became a small homelab. The device’s Debian installation process is characterized as involved; after setup, standard Linux tools support service management and containerization. The source does not give step-by-step installation instructions, so readers should not treat the article as a complete build guide.
The service list reflects a preference for small, single-purpose tools. Bosscher says a previous Kubernetes setup with Grafana and related monitoring components felt like overkill for this use. Beszel is used for host-level statistics and alerts, while Gatus checks service availability. The author notes some overlap between Beszel and Dozzle and says one could be removed if memory savings became necessary.
For DNS filtering, Bosscher reports that about 60% of queries were blocked after adding several blocklists. The report says most of those blocked queries appeared harmless to the author, while some might not be. It does not provide the measurement period, total query count, list configuration or an independent assessment of what was blocked, so the percentage should be read as an observation from this particular setup rather than a general result.
“A DNS blocker cannot block all bad requests (you’ll need a proper firewall for that), but it sure can block a whole lot.”
— Bosscher, on AdGuard Home
Limits of the Reported Setup
The source is an individual account, not a controlled test or independent review. It does not establish whether the $10 price remains available, how much electricity the device uses, how the listed services perform under heavier traffic, or how reliable the setup has been over time. The author also does not provide a complete inventory of installed services’ versions, configuration or security audits.
Several claims require particular caution. The reported 60% DNS-blocking figure lacks a time window and comparison basis, and the security of an AI agent with root-level access depends on its configuration and threat model. The report’s Cloudflare Tunnel privacy concern is the author’s stated trade-off, not evidence that traffic was accessed by a government agency. It is also unclear whether the upcoming Telegram rich-message feature for Zeroclaw was released after the report.
Possible Changes to the Homelab
Bosscher says the next Zeroclaw version is expected, with Telegram rich-message support tied to the author’s contribution; the source points readers to a pull request but gives no release date or confirmation that it has been merged. The author also says Dozzle and Beszel overlap, leaving open the possibility of removing one if memory becomes tight.
For readers considering a similar build, the immediate next steps are practical rather than a promised product milestone: verify the device’s current price and hardware details, check compatibility with the required software, and review access controls before exposing services remotely or granting an agent shell permissions. The report does not announce a new OpenStick release, a formal benchmark or a change in availability.
Key Questions
What is the OpenStick in this report?
It is a small computing device that Bosscher says cost $10 including shipping. The reported specifications include four 1 GHz ARM Cortex-A53 cores, 512 MB of RAM and 4 GB of eMMC storage. The source does not independently verify the price or specifications.
Which services does Bosscher run on it?
The list includes AdGuard Home for DNS filtering, Beszel and Gatus for monitoring, Dozzle for container logs, Fusion for RSS, Shiori for bookmarks and page archives, and Zeroclaw for Telegram-based server queries. CastSponsorSkip and Cloudflare Tunnel are also listed.
Can DNS filtering block every unwanted connection?
No. Bosscher says DNS filtering can block many domain requests but cannot block every unwanted request, and distinguishes it from using a firewall. The reported 60% blocked-query share applies to the author’s setup; its measurement period and comparison basis are not provided.
Is the setup a complete build guide?
No. The report names the operating system and services but describes installation only as involved. It does not provide full installation steps, security settings, power measurements or independent performance tests.
