Building and testing
One identical environment for the whole team, with AI assistants like Claude Code already installed. Nobody fights their laptop.
an afternoon's work, 4 h≈ 0.60 €
Sandboxes
A powerful computer in the cloud, ready in a minute.
You switch it on when you need it and it pauses itself when you don't. Your files stay where you left them and you only pay for the hours you use, from 0.15 € an hour.
Nothing to install on your laptop: you create it, use it and pause it from the panel.
how it works
Like renting an office, except it's a computer.
You come in, you work, and the clock stops when you leave. Everything stays exactly as you left it for next time.

It pauses itself when you finish
Stop using it and it pauses: you stop paying hours. Your files stay on its disk, which keeps billing monthly.
The only thing you pay for while paused is the disk your files live on: 5.00 € a month for 50 GB.
what people use it for
Plenty of power, without buying anything.
With the real cost right beside it, on real work.

see the full pricingwhat it costs
The clock only runs while you work.
You load credit in euros and every hour switched on takes its share. Paused it costs nothing. Your files sit on a separate volume, and that one is always billed, switched on or paused.
- You only pay for the hours it is switched on, from 0.15 € an hour on the entry plan.
- It pauses itself when you stop using it, so you don't overspend.
- The same credit works across the other GPU Flow products.

Sandboxes guides
Short videos recorded on the real panel: your Sandbox page, connecting over SSH and what happens when you pause or delete it.

Access over SSH or from the browser, templates with Claude Code and Open Code, and a persistent disk. The details are on its own page.
developer guidefrequently asked
What people ask before spinning one up.
Which templates are there?
Claude Code and OpenCode, preconfigured against Token Factory. Need another one? Tell us and we'll add it to the catalogue.
Do I lose my work when it suspends?
No. The volume is persistent: repos, datasets and checkpoints survive shutdown. On reconnect everything comes back in seconds, with nothing to reconfigure.
How do I connect?
Over SSH with your public key, like any machine. Your editor, your dotfiles and your usual workflow.
Does the Sandbox have a dedicated GPU?
Not today. The Sandbox uses the GPU via Token Factory over the internal RDMA network. A dedicated GPU inside the Sandbox is on the roadmap, with no committed date.
How is it billed?
Per active hour: when it auto-suspends, compute stops counting. The persistent volume is always billed, whether the Sandbox is active or suspended. Same balance as Token Factory and dedicated GPU, in euros.
Where is my data?
In our datacenter in Spain, on DDN EXAScaler storage. It never leaves Europe.
Your Sandbox can be ready in a minute.
You create the account, pick a size and get in. You can resize it or pause it whenever you like, without losing your work.
