01

Remote browsers

Connect to an already-running Chrome instance on another machine via CDP. No need to launch a browser locally.

02

Tab pooling

Reuse browser tabs across URLs instead of creating and destroying them. Pages reset between screenshots automatically.

03

Parallel execution

Run multiple tabs in parallel with configurable concurrency. Default 4, scale up to whatever your machine handles.

04

Flexible input

Single URL, file of URLs, or pipe from stdin. Works with any tool that outputs URLs.

05

Multiple formats

PNG, JPEG, WebP. Full page screenshots. NDJSON metadata output for automation and AI agents.

06

Runs everywhere

Linux, macOS, Windows, Termux. Single binary, no runtime dependencies beyond a Chromium browser.

Usage

Single URL
$ hxn -b $(which brave) -u https://example.com

Start headless Chrome on the remote machine
$ chromium --headless --remote-debugging-port=9222 --no-sandbox
# expose the port if Chrome only binds to localhost
$ socat TCP-LISTEN:9223,fork,reuseaddr,bind=0.0.0.0 TCP:127.0.0.1:9222 &
Connect via auto-discovery
$ hxn --remote-host 192.168.1.42:9223 -f urls.txt
Connect via WebSocket URL
$ hxn --remote-url ws://192.168.1.42:9223/devtools/browser/<uuid> -u https://example.com
Parallel tabs
$ hxn -b $(which brave) -f urls.txt --tabs 8
Custom pool size
$ hxn -b $(which brave) -f urls.txt --pool-size 16
With ports
$ hxn -b $(which brave) -f urls.txt --ports 8080,8081
NDJSON output
$ hxn -b $(which brave) -f urls.txt --json
Silent mode
$ hxn -b $(which brave) -f urls.txt --silent
Screenshot format

Run JavaScript before screenshot
$ hxn -b $(which brave) -u https://example.com \
    --javascript "document.querySelector('.banner')?.remove()"
Custom viewport + timeout
