# brow A browser rendering CLI. Take screenshots of web pages and render Excalidraw files to images using headless Chrome. `brow` does not bundle a browser. You install or provide one explicitly. ## Install ```bash curl -fsSL https://raw.githubusercontent.com/corespeed-io/brow/main/install.sh | bash ``` ### Build from source ```bash bun install bun run build ``` ## Browser setup Before rendering, you need a browser. Two options: ### Option 1: Install a managed browser ```bash brow browser install ``` Downloads Chrome for Testing to `~/.cache/brow`. This becomes the default runtime browser. ### Option 2: Bring your own Point to any Chrome/Chromium executable: ```bash brow --browser /usr/bin/google-chrome -m web -u https://example.com -o screenshot.png ``` ### Resolution order At runtime, `brow` resolves the browser in this order: 1. `--browser <path>` (explicit override) 2. Managed browser (via `brow browser install`) 3. Fail with actionable error ## Usage ``` brow -m <mode> -o <output> [options] ``` ### Web screenshots ```bash brow -m web -u https://example.com -o screenshot.png ``` | Flag | Default | Description | | --------------- | ------------ | ------------------------------------------ | | `-u, --url` | _(required)_ | URL to screenshot | | `--width` | `1280` | Viewport width in pixels | | `--height` | `800` | Viewport height in pixels | | `--full-page` | `true` | Capture the full scrollable page | | `-s, --scale` | `1` | Device scale factor (2 = retina/2x output) | The output image resolution is `width * scale` by `height * scale`. For example, `--width 1280 --height 800 --scale 2` produces a 2560x1600 image. ### Excalidraw rendering ```bash brow -m excalidraw -i drawing.excalidraw -o output.png ``` | Flag | Default | Description | | ------------- | ------------ | ------------------------------------ | | `-i, --input` | _(required)_ | Path to `.excalidraw` file | | `-t, --theme` | `light` | `light` or `dark` | | `-s, --scale` | `1` | Scale multiplier (2 = 2x resolution) | | `--width` | | Explicit output width in pixels | | `--height` | | Explicit output height in pixels | By default the output matches the drawing's natural dimensions. Use `--scale` to multiply them (e.g. `-s 3` on a 240x140 drawing produces 720x420), or `--width`/`--height` to set exact output dimensions. ### Global options | Flag | Description | | -------------- | ---------------------------------------------------- | | `-m, --mode` | Rendering mode: `web`, `excalidraw` (default: `web`) | | `-o, --output` | Output file path (required) | | `--browser` | Path to a browser executable | | `-h, --help` | Show help | ### Commands | Command | Description | | ---------------------- | ------------------------------------ | | `brow browser install` | Download and cache a managed browser | ## Adding a renderer Create a new file in `renderers/` that exports a `Renderer<TConfig>` and register it in `renderers/registry.ts`. Your renderer receives a Puppeteer `Page` and is responsible for navigating, rendering, and writing the output file.
