Your laptop is the whole infrastructure, and it is tired
Docker eats the RAM, the fan spins up, and the project only runs where the laptop is. Show it to a friend and you are screen-sharing localhost.
A VPS means an evening of setup and a pile of config to maintain before you write a line of product.
A weekend build
- Sat 10:00
Ready at login
Pick Start and keep the suggested name. Ubuntu 26.04 with Docker, Node 26 and Python 3.14 waits at login, and the first run asks for your project, agent and subscription.
- Sat 10:05
The agent builds, you steer
Ask OpenCode or Claude Code for the first version. Postgres runs in Docker right next to it.
- Sat 16:00
Open it on your phone
Your dev server has an HTTPS address on detachbox.dev. Make the port public and send it to a friend.
- Sun
Keep going from anywhere
Laptop, phone, a borrowed computer: the same terminals, the same scrollback.
What $39 gets you
Always-on Linux for $39 a month
2 vCPU, 4 GB, 50 GB and sudo on Ubuntu 26.04 LTS, running around the clock.
Every agent, on the plan you already pay for
Claude Code, Codex and OpenCode are installed. Run them on your subscription, or on a cheaper model with your own key.
A link instead of localhost
Every dev server gets an HTTPS address with hot reload, private until you make it public.
Break it, start fresh
Wreck a terminal with an experiment, end it and open a new one on a clean system. Your code waits in the project.

Questions about this
Is there a free tier or a student discount?
Start is $39 a month for all of it, students included, and a friend's invitation makes the first month free. Every Compute is paid, so no miners share your CPU.
Can I run a cheaper model than Claude or GPT?
Yes. Add a Z.ai or DeepSeek API key under Subscriptions & keys, then pick it under Runs on when you launch Claude Code, Codex or OpenCode. The same agent runs on that provider's models.
How do I get a clean system?
End the terminal and open a new one. It starts from the current image with nothing you installed, and mounts your project and home folder as you left them.
