Your own dev machine,
one click away.
Spin up a full Linux workspace in your browser — root access, persistent storage, nothing to install. Not tied to a lab or a lesson. Just yours.
Ubuntu 22.04 / 24.04 LTS 
AlmaLinux 9 — RHEL compatible A real environment, not a sandbox toy
Everything a local machine gives you, minus the setup.
One click, zero setup
Pick an OS, hit launch, and a full root shell opens in your browser. No installs, no Docker, no config.
Persistent by default
Your files, packages and history stick around between sessions. Pause it, come back tomorrow, pick up where you left off.
Real machine, full access
Root, sudo, your own kernel-backed environment. Install anything, run services, break things safely.
Build a template once. Hand it to every student.
Pre-configure a workspace — the OS, the tools, the starter files, the exact versions — and share it as a template. Your students launch an identical, ready-to-go environment in one click. No "works on my machine," no setup support tickets.
- Pin the OS, packages and dependencies so everyone starts from the same state
- Drop in starter code, datasets and instructions
- Share one link — students launch their own copy instantly
Every student gets a free workspace on your templates — 1 vCPU, 2 GB RAM, persistent storage. No card required.
Transparent. Most of it is free.
Every workspace is free — generous CPU, RAM and storage, no credit card, no hourly meter. Most of our 50+ supported tools run on it out of the box. The few that need real horsepower are Pro.

Free tools run on your free workspace. Pro tools — cloud simulators and heavy data platforms — need a bigger machine.
