A report by Bosscher describes using a $10 OpenStick as a low-power, passively cooled Debian homelab. The listed services include DNS filtering, monitoring, RSS, bookmark archiving and a Telegram-connected AI agent; the reported memory figures are the author’s own observations, not independent benchmarks.
Bosscher has described running a small collection of self-hosted services on a $10 OpenStick, a passively cooled device with 512 MB of RAM, four ARM Cortex-A53 cores and 4 GB of storage. The report offers a practical example of how a low-cost, limited-resource device can serve as a quiet home server, while its performance and software claims reflect the author’s own setup.
The OpenStick runs Debian, according to Bosscher, after an installation process the author characterizes as involved. Bosscher says the device has about 450 MB of usable RAM and 150 Mbit/s Wi-Fi, alongside a 4G modem, GPS and a programmable LED. Its passive cooling means it operates without a fan, the report says.
The service list includes AdGuard Home for DNS-level domain blocking, CastSponsorSkip for skipping sponsorships on Google Cast devices, and Cloudflare Tunnel for reaching services without opening ports on the home network. Bosscher reports that about 60% of DNS queries are blocked after adding blocklists, but the article does not provide a measurement period or an independent audit of what was blocked. The author also cautions that DNS filtering cannot replace a firewall.
For server and service oversight, Bosscher runs Beszel for resource graphs and alerts, Dozzle for viewing Podman container logs, and Gatus for checking whether services are available. Other listed applications include the Fusion RSS reader and Shiori, which manages and archives bookmarks. The author gives approximate memory figures for several applications, including 20 MB for Beszel’s agent and server combined, 22 MB for Fusion and about 10–20 MB for Shiori.
A Small Server for Everyday Services
The report matters to readers considering self-hosting because it shows a range of ordinary services running on hardware with very limited memory and storage. Instead of a general-purpose server build, Bosscher describes choosing applications with low reported memory use and assigning each a defined role, from RSS reading to uptime checks.
That approach may be useful for hobbyists who want to experiment without buying a larger machine or accepting fan noise and higher power use. However, the source gives no measured electricity costs, long-term reliability results or independent performance tests. The $10 purchase price also describes Bosscher’s acquisition, including shipping, and may not represent current availability or pricing.
The setup also illustrates trade-offs in exposing home services. Bosscher uses Cloudflare Tunnel to avoid opening network ports, while acknowledging a privacy concern around routing traffic through a third party. The article is an account of one person’s choices, not a security review or recommendation that the same configuration is appropriate for every home network.

How the OpenStick Fits In
Bosscher says the device was bought as an inexpensive hardware novelty and later used as a starting point for self-hosting. The report describes Debian support as the basis for running familiar Linux services, including systemd for service management and Podman for containers. It does not identify the exact OpenStick model, operating-system image or installation steps.
For the AI-agent component, Bosscher chose Zeroclaw after trying OpenClaw on a Kubernetes cluster. The author says OpenClaw used more than 1 GB of memory in that earlier setup and caused update and workflow problems; those comparisons are personal experience, not controlled tests. Bosscher reports Zeroclaw using about 3 MB of resident memory while idle and says it is used through Telegram to check logs and disk space. The agent has access to the OpenStick itself, described by the author as effectively a root shell, but not to anything beyond that device.
“For 10 dollars you basically get a home server with minimal power usage and zero noise!”
— Bosscher, describing the hardware
Limits of the Reported Setup
The source does not give the report’s publication date, the exact OpenStick model, current purchase availability or a reproducible installation guide. It also does not provide independent tests of memory use, performance, reliability or power consumption; the figures are the author’s estimates for this setup. The 60% DNS-blocking figure has no stated measurement window or comparison baseline, so it should be read as a reported observation rather than a general rate.
Security outcomes are also not independently assessed. The report does not detail the full Cloudflare Tunnel configuration, the blocklists used, or the controls around the AI agent’s root-level access. Bosscher notes the privacy trade-off of using Cloudflare, but the source does not establish what data the provider can access in this particular configuration.
Further Changes to the Homelab
Bosscher says a future Zeroclaw version may include rich-message support for Telegram, with the author contributing a pull request that readers can track. The source does not give a release date. The author also says Dozzle overlaps with Beszel in some monitoring functions and could be removed if saving another 10 or 20 MB becomes necessary.
No broader product announcement or formal performance study is described. The next developments to watch are the reported Zeroclaw update and any later account from Bosscher on how the device handles the services over time, including resource use, reliability and security changes.
Key Questions
What is an OpenStick in this report?
It is the small computing device Bosscher bought for $10 including shipping and used as a Debian home server. The report lists 512 MB of RAM, four 1 GHz ARM Cortex-A53 cores and 4 GB of eMMC storage.
Which services does Bosscher run on it?
The report lists tools for DNS filtering, Cast sponsorship skipping, monitoring, container logs, service checks, RSS reading and bookmark archiving. It also describes Zeroclaw, an AI agent used through Telegram to check the server.
Are the memory figures independently tested?
No independent testing is provided. The application memory figures are the author’s reported estimates for this particular setup, and may vary with configuration, workload and software versions.
Does DNS blocking secure the whole network?
No. Bosscher explicitly says DNS blocking cannot stop every unwanted request and is not a substitute for a proper firewall. The report does not present a complete security assessment of the homelab.
What is planned next?
Bosscher says a future Zeroclaw release may add rich-message support for Telegram through a pull request the author contributed. No release date is given, and the source describes no confirmed schedule for other changes.
