Reefy turns any PC, mini PC, laptop, or GPU box into a private AI server. Unlike a traditional Linux install, there’s no setup: flash a USB drive, boot, and adopt it in your dashboard. Built with Buildroot for fast boot, NVIDIA GPU support, safe A/B upgrades, encrypted backups, remote access, and AI apps like OpenClaw, Hermes, Ollama, vLLM, SGLang, and more.
Hey Product Hunt 👋
I’m Abylay, founder of Reefy.
I built Reefy because I had 8 machines sitting at home collecting dust: Intel NUCs, mini PCs, a Surface laptop, and two NVIDIA GPU boxes I built with my kids.
The hardware was fine. The setup was the problem.
Installing Linux, Docker, NVIDIA drivers, networking, remote access, backups, and updates turns a simple weekend project into a pile of half-working machines.
So I built Reefy.
Reefy turns spare PCs, mini PCs, laptops, and GPU boxes into private AI machines.
Flash the Reefy image to a USB drive, boot the machine, and it appears in your dashboard at reefy.ai. Click “Adopt,” and now you can start OpenClaw, Hermes, Ollama, Frigate, vLLM, SGLang, and other local AI workloads in one click.
You can run multiple isolated agents too: one for personal use, one for business, one for family, or one per experiment.
Reefy also includes:
• NVIDIA GPU autodetection and drivers out of the box
• Encrypted app backups
• A/B OS upgrades with rollback if the new image fails
• Remote access from anywhere
• Estimated cloud cost saved based on your hardware and uptime
The goal is simple:
Make private local AI infrastructure as easy as flashing a USB drive.

I can’t wait to see what machines you bring back to life and what AI workloads you run on your own hardware. Tell me in the comments.
@aospan1 The A/B partition upgrade is the detail that got me. I've bricked a headless box before with a bad kernel update and had to physically pull the drive and fix it from another machine.
Curious how rollback works in practice. Does it flip back automatically if boot fails, or is there some health check that has to time out first?
@whetlan Yep! Rollback is automatic - UEFI's BootNext is single-use, so the new slot only gets one boot attempt. A small post-boot service has ~6 min to confirm health and promote the slot to permanent BootOrder; anything short of that and the next reboot just drops back to the old slot.
On top of that, the motherboard's hardware watchdog (pet by systemd, fires at 120s) catches the case where the kernel hangs so hard nothing in userspace can react — the board self-resets, and BootNext takes over from there. So even a fully bricked boot ends up on the old slot after one reboot cycle.
This approach was inspired by fault-tolerant update systems used in projects like SpaceX Starlink satellites, where failed remote updates are not an option. For anyone interested, Starlink published a great paper on reliable over-the-vacuum updates for thousands of satellites:

I have spare hardware and was recently trying to set up local agents with OpenClaw but facing different issues with different distros..this seems like a convenient solution to my problem so ill definitely give this a try and provide feedback once everything is setup and running smoothly (or not :p).
Just curious, are outdated/old Nvidia and Intel drivers supported and are the updates automatic to the "reefs" and the system itself or does it need to be done manually?
@marut_tewari Thanks Marut, this is exactly the kind of setup Reefy was built for :)
NVIDIA support is built in, so the goal is no distro-hopping or driver-install dance. Older NVIDIA GPUs should work as long as they are still supported by the bundled NVIDIA driver branch.
For Intel, basic support comes through the Linux kernel and standard drivers, though some mini PCs hide things like fan sensors behind vendor-specific firmware, so hardware feedback helps a lot.
Reefy system updates are automatic and use an A/B update model with rollback.
Would love to hear what works or breaks on your setup 😄
if reefy actually handles nvidia driver installation out of the box, you’ve already won. 🫡
The 'estimated cloud cost saved' feature is so smart. it’s the best way to justify the power bill to my wife! haha. but seriously, seeing the ROI of your own hardware in real-time makes running local ai feel like a much better investment.
Really great
Fun technical detail: Reefy uses A/B OS upgrades.
The new OS image is written to the inactive partition. The machine tries to boot into it, and if something goes wrong, it rolls back to the previous working system.

A bit of backstory: Reefy came from my own pile of machines at home.
One of them was a quiet AMD EPYC home server I built with my kids, which I shared here:
https://www.reddit.com/r/homelab/comments/1hmnnwg/built_a_powerful_and_silent_amd_epyc_home_server/
That project made the problem very clear: the hardware is powerful, but turning it into something reliable and easy to use takes too much work.
Reefy is my attempt to make that kind of hardware useful in minutes.
