​
Overview

You can run Stably CLI browser-backed commands in cloud browsers. This is especially useful in CI, and each subagent gets its own isolated browser session automatically.
Useful when you:
  • Don’t want to manage browser infra
  • Want to parallelize commands like stably create and stably fix to run faster

​
Supported Commands

Cloud browser mode applies to the browser-backed agent commands:
  • stably
  • stably create
  • stably fix
  • stably verify
It does not change how stably test works. Normal Playwright test execution still runs in your own environment.

​
How to Enable It

Use either the CLI flag or the environment variable:
You can use --browser=cloud on the root command or the subcommand. These are equivalent:

​
Limits

  • Cloud browser mode is for browser-backed agent commands, not stably test
  • The browser is remote, but your filesystem is still local to the machine running the CLI
  • stably fix still requires a git repository because fixes are applied to local files

CLI Commands

See the full command reference and shared global options.

Create Tests

Use cloud browsers during test generation.

Fix Tests

Run autofix in a remote browser while editing your local repo.

Verify with AI Agents

Use stably verify with a cloud browser.
