Longshot

Full-page screenshots that come out right. Sticky headers are suppressed after the first tile instead of repeating down the image, and overflow panes (Gmail-style inner scrollers) are captured when the page itself does not scroll. Nothing is uploaded.

Two ways to run it, one capture engine behind both:

• Browser extension for Chrome and Brave, driven by hand. Capture, crop, annotate, copy, download, or save as PDF. See Install.
• Headless CLI (@craigcossairt/longshot) for scripts, CI, and coding agents. See CLI.

There is no website to run.

What it does

• Full page, visible viewport, or drag to select an area
• Sticky headers hidden after the first tile so they are not repeated
• Overflow panes (Gmail-style inner scrollers) captured when the page itself does not scroll
• Editor: crop, pen, shapes, text, stamps, undo/redo
• Export PNG, JPEG, WebP, AVIF, or PDF
• Files page for recent captures
• Optional one-click toolbar capture
• Optional skip-the-editor path that copies to the clipboard (or downloads)
• Keyboard shortcut: Alt+Shift+L captures the full page
• Optional CLI for unattended / agent captures (cli/)

Install (unpacked)

Sideload is the supported install. A Chrome Web Store listing is not published.

1. Clone this repo.
2. Open chrome://extensions or brave://extensions.
3. Turn on Developer mode.
4. Load unpacked and choose the extension/ folder.

Right-click the toolbar icon → Options for format, folder, one-click capture, skip-the-editor, inner frames, and overflow panes. If one-click is on, the icon starts a capture instead of opening the menu. Scroll overflow panes is on by default: when the page itself does not scroll, Longshot captures the main overflow: auto feed instead.

CLI (optional)

Package: @craigcossairt/longshot. The command is longshot.

npm install -g @craigcossairt/longshot
longshot --url https://example.com --full-page --out capture.png

From a clone:

npm install
npx longshot --url https://example.com --full-page --out capture.png

See cli/README.md for engines, exit codes, and --cdp.
