# Dev Browser

Dev Browser controls browsers via sandboxed JavaScript scripts with persistent page state. Use it to navigate websites, fill forms, take screenshots, extract web data, test web apps, or automate browser workflows.

**Install:**

```bash
npx degit https://github.com/SawyerHood/dev-browser/tree/main/skills/dev-browser ~/.claude/skills/dev-browser
```

## README

# Dev Browser

A CLI for controlling browsers with sandboxed JavaScript scripts.

## Installation

```bash
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.
