For a while, my personal infrastructure lived on a small Hetzner VPS. It ran a few web apps, a remote browser called Surf , Caddy, and the usual supporting cast. Nothing particularly serious. It worked, I just didn’t like paying for it.
One of the apps I run, Surf, made the compromise difficult to ignore. The cheapest shared machines were fine until Chrome had real work to do, at which point they felt starved. Dedicated CPU machines fix that, but cost enough each month to make a personal browser feel like a questionable financial commitment.
Buying another machine wasn’t an appealing escape hatch either. DRAM prices have gone completely stupid , so putting together a new box with a comfortable amount of memory felt especially ill timed. I looked at used mini PCs and briefly considered turning my desktop into a server whenever I wasn’t using it. Then I remembered the CMF Phone 1 I already own.
Eight ARM cores, 8 GB of RAM, 128 GB of flash, Wi-Fi 6, a 5G modem, and a built in battery backup, that is all attached to an SoC that I feel is overqualified for sitting in a drawer. And I had already paid for it. After dusting it off and playing with it for a while, I decided to turn the phone into the server.
Today it runs Surf and its managed Chrome instance, my personal finance tracker, a screen sharing service, and a handful of smaller web apps. They survive reboots, deploy from Git, and remain reachable when the phone moves between networks, so this is now the machine that actually replaced the VPS.
The cleanest version of this idea seemed to be flashing a normal Linux distribution. The CMF Phone 1 has a postmarketOS device port, it boots, and the device page has enough green boxes to make a reckless person optimistic. I ended up being that person.
