A report by Bosscher describes turning a $10 OpenStick into a small Debian-based homelab for lightweight self-hosted applications. The device runs services including DNS filtering, server monitoring, RSS, bookmarks and an AI agent, though the account does not provide independent performance testing or a full cost breakdown.
In a report on a $10 OpenStick, blogger Bosscher describes running a collection of self-hosted services on the small, low-power device, including DNS filtering, monitoring, RSS and an AI agent. The account offers a practical example of how inexpensive hardware can support a modest Debian-based homelab, while the device’s limited memory and storage constrain what it can comfortably run.
Bosscher says the OpenStick cost $10 including shipping and has 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. It is passively cooled, which Bosscher describes as silent. The device requires a somewhat involved installation, according to the report, and runs Debian once set up, allowing the use of systemd and Podman.
The software list is built around keeping memory demands low. 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 which domains are blocked. Bosscher also runs CastSponsorSkip, a service described as skipping sponsorship segments and sometimes ads on Google Cast devices.
Other services include Zeroclaw, an AI agent harness that Bosscher says uses about 3 MB of memory at idle; Cloudflare Tunnel, reported at 8–20 MB; and Beszel for resource monitoring and alerts, at about 20 MB across its server and agent. Dozzle provides a web interface for Podman container logs, while Gatus checks whether services are available. Bosscher also lists Fusion for RSS at 22 MB and Shiori for bookmarks and website archiving at roughly 10–20 MB. These figures are the author’s reported usage, not independent benchmarks.
Small Hardware, Practical Services
The report matters to readers interested in self-hosting because it shows a use case built around small, focused services rather than a large server or complex monitoring stack. A device at this price could offer a low-cost way to experiment with Linux administration, containers and network services, provided users accept the limits of its memory, storage and processing power.
Bosscher’s examples also illustrate the trade-offs of putting services on one small machine. Local DNS filtering and monitoring can be useful, but the hardware is not a substitute for a firewall or a backup system. The report itself cautions that DNS blocking cannot stop every unwanted connection. The services’ availability also depends on the OpenStick remaining powered, connected and operational.
The AI-agent setup carries a separate security consideration. Bosscher says Zeroclaw has access to the OpenStick itself, effectively giving it a root shell, but not to other systems. That arrangement limits the described scope, yet a privileged agent can still affect the device and services hosted on it. Readers considering a similar setup would need to weigh convenience against the access granted and the risks of exposing services remotely.

From Novelty Device to Debian Server
Bosscher says the OpenStick was bought on a whim as a novelty, then became a starter platform for self-hosting. The report contrasts its modest specifications with larger setups the author had used: Bosscher says an earlier Kubernetes installation running OpenClaw consumed more than 1 GB of memory and was frustrating to maintain. By comparison, the author describes Zeroclaw as using about 3 MB at idle and meeting their needs.
The author says Zeroclaw was selected over alternatives including Picoclaw and Nullclaw because its documentation and community appeared stronger. Bosscher also notes contributing a change for richer Telegram messages, with a pull request linked in the original report. Separately, the author says Grafana and its associated monitoring stack felt excessive for this device and preferred Beszel for simpler resource graphs and alerts.
These comparisons reflect Bosscher’s own experience and preferences, not controlled tests of the applications. The report’s software memory figures can vary with configuration, workload and version. It also notes that Bosscher uses a personal AdGuard Home fork for handling large blocklists efficiently, while advising readers not to run binaries from untrusted sources and pointing to the official version as an alternative for smaller lists.
“A DNS blocker cannot block all bad requests (you’ll need a proper firewall for that), but it sure can block a whole lot.”

Limits of the Reported Setup
The source is a personal account, not a benchmark or independent review. It does not state the report’s publication date, provide measured power consumption, or explain whether the $10 price remains available. The operating conditions behind the software memory estimates are not detailed, and the report does not quantify uptime, network throughput or performance under simultaneous workloads.
It is also unclear how the author’s DNS-blocking percentage was measured or what time period it covers. The list of applications describes Bosscher’s configuration; it does not establish that every service will fit or perform the same way on another OpenStick. No independent security assessment of the listed tools or the author’s particular configuration is included.
Further Details Depend on Testing
The report does not announce a product launch, planned release or formal test, so there is no stated next milestone. Bosscher says a future Zeroclaw version may include richer Telegram message support, with the author’s contribution tracked through a pull request. Whether and when that change ships is not established in the supplied account.
For readers evaluating a similar build, the next useful evidence would be repeatable measurements of power use, memory under load, uptime and application behavior, alongside details about the exact software versions and configuration. Until then, the account is best read as a documented example of one person’s setup rather than a guarantee that the same collection of services will run identically on every device.
Key Questions
What is an OpenStick?
In Bosscher’s account, it is a small computer with 512 MB of RAM, four ARM Cortex-A53 cores, 4 GB of eMMC storage, Wi-Fi, a 4G modem and GPS. The author says it runs Debian after installation.
Which services does Bosscher run on it?
The reported setup includes DNS filtering with AdGuard Home, CastSponsorSkip, Zeroclaw, Cloudflare Tunnel, Beszel, Dozzle, Gatus, Fusion and Shiori. The report lists the author’s own configuration and memory estimates.
Does DNS filtering block every unwanted connection?
No. Bosscher explicitly says DNS blocking cannot stop all unwanted requests and says a firewall is needed for broader protection. The reported 60% blocked-query figure is the author’s observation, with its measurement window and method unspecified.
Is the setup independently tested?
No independent testing is included in the supplied report. The performance and memory figures are attributed to Bosscher and may differ with software versions, settings and workload.
