Use for headless browser automation and QA: "automate browser", "QA test this site", "scrape webpage", "take screenshot", "automate login", "find bugs on this page". Rust CLI with QA health scores, diff-aware regression, named session profiles and cloud providers. Not for the user's real Chrome (use /browser-harness).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# agent-browser
A fast native Rust CLI for headless browser automation, designed specifically for AI agents. No Playwright or Node.js required for the daemon.
## Installation
```bash
npm install -g agent-browser
agent-browser install # Downloads Chrome for Testing (first time only)
```
On Linux, add `--with-deps` to install system dependencies.
## Core AI Workflow (Always Use This Pattern)
```bash
# 1. Open page
agent-browser open <url>
# 2. Get interactive elements with refs
agent-browser snapshot -i --json
# 3. Interact using refs from snapshot
agent-browser click @e2
agent-browser fill @e3 "input text"
# 4. Re-snapshot after page changes
agent-browser snapshot -i --json
```
**Refs are the preferred selector method for AI.** They come from `snapshot` output like:
```
- button "Submit" [ref=e2]
- textbox "Email" [ref=e3]
```
Then use `@e2`, `@e3` in subsequent commands.
## Essential Commands
### Navigation & Interaction
```bash
agent-browser open <url> # Navigate (aliases: goto, navigate)
agent-browser click <sel> # Click element
agent-browser fill <sel> <text> # Clear and fill input
…
The line at the top of this page pins the label git:20261007.04729ed, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
