A developer running a $10 OpenStick—a compact ARM-based device—has documented how to turn it into a functional homelab server capable of hosting multiple services simultaneously.
The OpenStick hardware specifications are modest: 512 MB of RAM (approximately 450 MB usable), four ARM Cortex-A53 CPU cores at 1 GHz, 4 GB eMMC flash storage, 150 Mbit/s Wi-Fi, a 4G modem, GPS, and passive cooling for silent operation. Despite these constraints, the device runs Debian Linux with systemd and Podman, enabling lightweight containerization suitable for self-hosting projects.
According to the blog post, several applications run efficiently on the platform. AdGuard Home, a DNS-level ad and malware blocker, consumes roughly 40 MB and blocks approximately 60% of DNS queries after configuration with blocklists. CastSponsorSkip automatically skips sponsorships in YouTube streams on Google Cast devices while using only 5–10 MB. Fusion, an RSS reader, occupies 22 MB and replaced Google Reader as the author’s preferred alternative to paid services like Feedly.
For monitoring and alerting, the developer deployed Beszel (20 MB total) to track memory and CPU usage with built-in Telegram notifications, and Gatus (10 MB) to monitor service health. Zeroclaw (64 MB), an AI agent harness supporting 30 messaging channels, provides system monitoring through Telegram even with limited connectivity. Shiori (~10–20 MB) serves as a bookmark manager with automatic website archiving.
Cloudflare Tunnel (~8–20 MB) securely exposes services to the internet without port forwarding. Diun (9 MB) sends Telegram notifications when container updates are available.
The author notes that while the OpenStick is less powerful than a modern smartwatch, the combination of minimal power consumption, silent operation, and ability to run standard Linux containerization tools makes it practical for homelab experimentation. Installation involves additional complexity, but once configured, the device functions as a home server suitable for various lightweight self-hosting tasks.
