AI workspace · Swiss hosted

Give your coding agent Superpowers.

A real Linux workspace for your AI agent. Install software, write code and run your services, with root access and files that stay.

Build a URL shortener with PostgreSQL.

One task. A workspace to build it in.

Write and edit project files

// /work/url-shortener/server.js
app.post('/links', async (req, res) => {
  const link = await saveLink(req.body.url);
  res.json({ short: link.slug });
});

The agent works with files in your container.

Run commands with root access

# Example commands, not a recorded run
$ npm install
$ npm test
$ npm run dev

Inspect the commands and their output in the terminal.

Open what you are building

Keep the project in your workspace

Files stay when the conversation ends. Idle containers can sleep.
