Stacks
Ready-made development environments with your coding agent already installed. Pick a stack, pick your agent, and paste three commands.
A stack is a workstation set up for one kind of work, with the tools a developer expects to find and the coding agent you use already installed. Each stack is a file in our public examples repository, and you apply it straight from its URL, so there is nothing to download or write first.
Each stack has one file per agent: Claude Code, Codex, the Cursor CLI and the Antigravity CLI. The files differ only in which agent they install.
These are the stacks available today:
- Front-end: Node.js, Playwright and the GitHub CLI, with an optional React starter app.
A stack runs on your own computer, in a virtual machine, with no account needed. Each stack’s page also says how to change it to suit you and how to run it in a cloud.
