Coming soon · private beta
Computers for your agents.
One SSH away.
Persistent or ephemeral Linux virtual machines with root and Docker, and your agents preinstalled. Keep a box for months, or spin one up and throw it away. They sleep when idle, memory and all, and wake the moment you connect. From $3/month.
$ ssh devlbox.comOpens at launch.
Waitlist opens soon.
How it works
- 1
ssh devlbox.com
No app, no browser. Your SSH key is your login.
- 2
Pick an environment or bring your own
Choose one of our agent-first development environments, or bring anything that runs as a Docker or OCI image. You can extend ours, too.

You're in
Root, Docker, Claude Code, Codex and opencode are ready. Leave whenever you like; it sleeps, and you come back to the same state.
Built for long-running agents
A pool, not a box
Split CPU, RAM and disk however you like; sleeping boxes only use disk.
Dedicated virtual machines
Every box has its own kernel; root, systemd and Docker.
Sleeps, doesn't die
Memory, processes, tmux and agent sessions come back intact.
Knows when agents work
We know when your agent is idle, so a box only sleeps when your agents have stopped.
Fork and snapshot
Fork a running box to run agents in parallel.
HTTPS for every box
Private by default, shareable with a link, public when you want.
Built for agents
API, MCP server, scoped agent keys and spending caps.
Your agents' machines can talk to each other
Put boxes on a private network and they reach each other. Everything else stays isolated, and nobody else's boxes can ever join.
Pricing
From $3/month.
Every plan is a pool of CPU, RAM and disk. Run as many boxes as fit, and only awake boxes count. Boxes sleep after hours of idle, not minutes. No free tier, and no surprise bills: going past your plan is opt-in, with a spending cap.

FAQ
What is a box?
A dedicated Linux virtual machine with its own kernel, root access, systemd and Docker. You reach it over SSH. A persistent box keeps its disk, memory and processes between visits; an ephemeral one is made to be thrown away.
How does sleeping work?
After hours of idle, not minutes, a box is saved to disk, memory included, and stops using CPU and RAM. When you connect, it wakes and picks up where it left off. Sleeping boxes only use disk.
Which agents work?
Claude Code, Codex and opencode are preinstalled, and we know when they are working or waiting, so a box never sleeps under a busy agent. Anything that runs on Linux works too.
Do I need to install anything?
No. If you have an SSH client and an SSH key, you can connect. There is no app and no browser step.
Can I use my own image?
Yes. Start from one of our agent-first environments and extend it, or bring any Docker or OCI image.
Where are the servers?
In Germany, in the EU. The company is in the Netherlands, and GDPR applies.
Is there a free tier?
No. Plans start at $3 a month.
When do you launch?
Private beta invites go out in batches from the waitlist.
