Renting out a GPU means letting someone run their own code on your computer — that is the whole point. So the real question is what that code can reach. Here is how RentGPUPower keeps it contained, what stays in your hands, and the trade-offs that remain.

Where a renter's code runs

The RentGPUPower app runs every rental inside a Docker container: a sandbox with its own files, its own processes and its own network. From inside it, a renter:

  • cannot see your files. The container has its own workspace, and nothing of yours is put into it.
  • cannot gain privileges. Containers start with "no new privileges", so nothing inside can raise itself above the rights it started with, and raw network sockets are dropped, so it cannot forge traffic on your network.
  • is kept apart from other renters. Each rental gets its own network, so two people renting two cards in the same machine cannot reach each other.
  • only sees the GPU you listed — or all of them, if you list the whole machine.
  • works within ceilings on memory (with no swap), processor use and the number of processes.
  • cannot fill your drive. A disk floor stops renter work before your free space runs out, and refuses — or stops — a Docker image download that would cross it.

Nothing is opened on your router either: renters reach their container through RentGPUPower, over your machine's own outgoing connection. When a rental ends, its container and its files are removed.

What stays in your hands

  • Pause or stop any time. Pausing hides your listing so nobody new can book it, and a rental already running finishes. Going offline ends a running rental early: you are paid for the time delivered, and the renter gets the rest back.
  • How the machine earns: rentals only, the cluster API only, or both.
  • Your price, for every rental booked from then on.
  • An honest listing. The app detects the hardware itself, so the listing always matches the machine, and renters get the card, memory and processor they were shown.

Money and your account

  • Escrow. Renters pay before a rental starts. The money is held and released to you as your machine delivers, so you never chase a payment.
  • Reliability scores. Every listing shows its real uptime history, so hosts who stay online stand out.
  • Two-step verification. Protect your account — and your earnings — with a code from an authenticator app when you sign in.

The honest trade-offs

  • Your internet connection and electricity are used while someone rents: renters download models and data, and the card works hard.
  • Without the Docker sandbox, a machine can still be rented, but only with a warning on its listing, because renter code then runs directly on your computer. That is fine for a dedicated machine, not for the PC you keep your life on. The cluster API only sends work to sandboxed machines.
  • A container is a strong wall, not a magic one. Keep your system and Docker up to date, as you would anyway.

Practical tips

  • Use a separate user account for hosting on Windows or macOS if you like, so your own files live under a different user altogether.
  • Keep the app current. It updates itself while it is open — never during a rental — and checks every new version against its published signature before using it.
  • Keep the computer awake while it hosts — the app has a setting for it — so sleep does not cut a rental short.

FAQ

Can a renter see my files or photos?

No. Their code runs in a Docker container with its own workspace, and your files are never placed in it.

Does hosting open a port on my router?

No. Renters reach their container through RentGPUPower, over your machine's own outgoing connection. Nothing needs opening on your router.

What if I need my PC back right now?

Pause the listing so nobody new can book it. If a rental is running and you cannot wait, go offline: you are paid for the time delivered, the renter gets the rest back, and your reliability score notes the interruption.

Can renters fill up my disk?

No. The disk floor stops their work before your free space runs out and refuses image downloads that would cross it, and a rental's files are deleted when it ends.
