About this skill
Dev Browser
A CLI for controlling browsers with sandboxed JavaScript scripts.
Installation
npm install -g dev-browser
dev-browser install
Usage
Run dev-browser --help to learn more.
Named daemon-launched browsers persist by default. For unattended work, --idle-timeout 5m closes each launched browser after inactivity while preserving its profile and login state. The setting never closes Chrome attached with --connect; use --idle-timeout 0 to disable configured cleanup.
When not to use it
- →Non-browser based automation tasks
- →Environments where CLI installation is restricted
Prerequisites
Limitations
- →Requires manual installation of browser binaries via CLI
- →Idle timeout settings may prematurely close browsers if not configured correctly
How it compares
