Corespeed Excalidraw Rendering — Browser Rendering CLI

Render Excalidraw files to PNG and capture web page screenshots using headless Chrome.

Workflow

Ensure brow is installed
Install the managed browser: brow browser install
Run brow --help to see all available options
Run the rendering command

Prerequisites

If brow is not installed:

curl -fsSL https://raw.githubusercontent.com/corespeed-io/brow/main/install.sh | bash

Before first render, install the managed browser (safe to re-run):

brow browser install

Usage

Run brow --help for the full CLI reference. Quick examples:

# Render Excalidraw to PNG
brow -m excalidraw -i drawing.excalidraw -o output.png

# Screenshot a web page
brow -u https://example.com -o screenshot.png

Notes

Browser auto-managed. brow browser install downloads Chrome to a local cache. No system Chrome required.
Use timestamps in filenames: yyyy-mm-dd-hh-mm-ss-name.png.
Do not read generated images back; report the saved path only.
