High-clock Windows · US-East · by the hour

A fast Windows box,
up when you need one.

No monthly plan, no contract, no box sitting idle burning money. Launch one, RDP straight in, stop when you're done — the meter only moves while it's running. Your setup's still there next time, and it's sat in US-East for the latency.

Base

The cheapest way to keep a machine on hand. Small, quick to start, and fine to leave sitting between sessions.

Built for how you actually use it
Keep your setup
Your disk sticks around between sessions by default — apps, proxies, and settings right where you left them. Encrypted, and gone for good the moment you terminate or switch it off.
Stays up until you say
No idle auto-stop unless you want one. The box runs until you stop it or the balance runs out, and the meter only moves while it's on. Flip on idle-stop in Settings if you'd rather it catch you when you forget.
No plan to outgrow
Need more cores next time? Launch a bigger one. Nothing to upgrade, no ticket to raise, no fee for switching — every size is on the same screen, and you pay that machine's rate only while it's on.
Locked to you
One open port, to one address. Remote Desktop opens to your IP alone, only while the box is up, and closes the moment it stops. Nobody else gets a look in.
Nothing monthly
No subscription, no invoice, no card on file charged later. Balance is prepaid, so you can't spend past what you put in and there's nothing to cancel if you walk away for a month.
How it works
01
Drop in a few dollars
Top up with card or crypto. A dollar's a dollar — no markup, no minimum you'll regret.
02
Pick a size and fire it up
Choose your cores, hit launch, give Windows a couple minutes to come up.
03
RDP in and go
Grab the Remote Desktop file, sign in, it's yours. Stop it when you're done and pick it back up next time.

Ready when you are.

Make an account, drop in a few dollars, launch your first machine. Takes about as long as reading this did.
