A developer’s account details how a $10 OpenStick, a small ARM device with 512 MB of RAM and 4 GB of storage, runs a collection of lightweight self-hosted services on Debian. The setup includes DNS filtering, monitoring, RSS and bookmark tools, and a Telegram-connected AI agent; the results are the author’s experience, not independent performance testing.
A developer has described running a collection of self-hosted services on a $10 OpenStick, a compact device with 512 MB of RAM, four 1 GHz ARM Cortex-A53 cores and 4 GB of eMMC storage. The report offers a practical example of how modest hardware can support lightweight home-server tasks, while its performance and security observations reflect one user’s setup rather than independent testing.
According to the report by Bosscher, the OpenStick cost $10 including shipping. The device also has Wi-Fi, a 4G modem and GPS, and uses passive cooling, which the author says makes it silent. About 450 MB of its 512 MB of RAM is usable. The author says installation takes some effort, after which the device runs Debian and supports systemd and Podman.
The listed services include AdGuard Home for DNS-level domain blocking, Beszel for resource monitoring and alerts, Gatus for checking whether services are reachable, and Dozzle for viewing Podman container logs. The author also runs Fusion for RSS feeds and Shiori for bookmarks and saved webpage copies. Reported memory figures range from about 10 MB for Gatus to roughly 40 MB for the author’s AdGuard Home version; these are the author’s figures and may vary by configuration.
Other tools in the setup include CastSponsorSkip, which the author says skips sponsorship segments on Google Cast playback, and Cloudflare Tunnel for reaching services without directly opening ports. The author also runs Zeroclaw, an AI agent that can communicate through channels including Telegram. Bosscher reports that it uses about 3 MB of RAM while idle and is used to check the OpenStick’s logs and disk space. The agent has access to the device itself, described by the author as effectively a root shell, but not to anything beyond it.
Small Hardware, Practical Services
The report illustrates a low-cost route into self-hosting: a single small device can host several personal services without the power draw and noise of a larger computer, according to its owner. That can make experimentation more accessible to people who want to learn Linux services and containers without first buying a conventional server.
The example also shows the limits of that approach. With 4 GB of storage and roughly 450 MB of usable memory, software choice and resource use matter. The author favors tools with small reported footprints and describes some as overlapping: Dozzle and Beszel both help with server visibility, though their interfaces and monitoring functions differ. The setup is a personal arrangement, not evidence that every listed service will run equally well on every OpenStick or configuration.
There are security trade-offs alongside the cost savings. DNS filtering can block requests to listed domains, but the author acknowledges it cannot replace a firewall. A tunnel service avoids exposing ports directly, but places some traffic and access arrangements within a third-party service. Giving an AI agent root-level access also carries risk, even if the author says its access is confined to this device. Readers considering a similar setup should review permissions, network exposure and trust in software sources.

From Novelty Device to Debian Server
Bosscher says the OpenStick was bought on a whim as an inexpensive hardware novelty. Its specifications are modest by current desktop standards, but the author argues that they are sufficient for a collection of lightweight services. The report does not describe a benchmark or controlled comparison; it recounts what the author has installed and how those tools fit the author’s needs.
The author contrasts Zeroclaw with a previous experience running OpenClaw on a Kubernetes cluster, saying that OpenClaw used more than 1 GB of memory and that updates disrupted workflows. Bosscher says Zeroclaw better fits this particular device and use case, citing its documentation, community activity and reported idle memory use. Those comparisons are personal assessments, not a general evaluation of the projects.
For DNS filtering, the author uses a personal AdGuard Home fork said to handle large blocklists efficiently, while warning readers against running binaries from unknown sources. The report also lists the official version as an alternative for smaller blocklists. Bosscher says about 60% of DNS queries are blocked after adding several lists, but supplies no measurement period or comparison baseline; the figure should be read as a reported observation from this setup, not a general rate.
“For 10 dollars you basically get a home server with minimal power usage and zero noise!”
— Bosscher, the report’s author
Performance and Security Limits
The report does not provide independent measurements of power consumption, sustained performance, temperature or reliability, nor does it specify how the services behave under heavier traffic. It also does not give a measurement window for the claim that 60% of DNS queries are blocked, or detail the contents of the blocklists.
Security depends on how each service is configured, which software binaries are trusted and what access is granted. The author acknowledges that the AI agent has root-level access to the OpenStick and that a tunnel service introduces a third-party component. The source does not provide an external security review, a full threat model or evidence that the configuration is suitable for sensitive workloads. Availability of the device, its current price and the exact installation steps are also not established in the supplied report.
No Follow-Up Milestone Given
The report describes a working personal setup but gives no planned product launch, testing schedule or follow-up date. Bosscher says rich-message support for Telegram is hoped for in a future Zeroclaw version and points readers to a pull request, but the source does not state when that version will be released or whether the change has been accepted.
For readers assessing the approach, the immediate next step is to check the device’s current availability and compatibility, then verify installation instructions and software sources before granting network or system access. The author’s account provides a starting point for evaluating what may fit on low-memory hardware; it does not establish that the same software versions, resource use or security outcomes will apply elsewhere.
Key Questions
What are the OpenStick’s reported specifications?
The report lists 512 MB of RAM (about 450 MB usable), four 1 GHz ARM Cortex-A53 cores, 4 GB of eMMC storage, Wi-Fi, a 4G modem and GPS.
Which services does the author run?
The list includes AdGuard Home, Beszel, Dozzle, Gatus, Fusion, Shiori, CastSponsorSkip, Cloudflare Tunnel and the Zeroclaw AI agent. The author says the device runs Debian and Podman.
Does DNS blocking stop every unwanted connection?
No. The author says DNS filtering blocks requests to listed domains but cannot block all unwanted requests and does not replace a properly configured firewall.
Is the setup independently tested?
Not in the supplied material. The memory figures and performance observations come from Bosscher’s personal report; no independent benchmark or security review is provided.
