Can we rebuild Full Page Screen Capture?

Build a Chrome extension like Full Page Screen Capture — a Full Page Screen Capture alternative you own.

You can build your own Full Page Screen Capture Chrome extension in a single sitting. Instead of relying on a third-party tool that requires broad page permissions, you can create a private, tailored alternative that captures full scrolling pages and lets you annotate them without sending your screen data anywhere.

The listing record

What Full Page Screen Capture does

Full Page Screen Capture — the all-in-one screenshot & annotation tool for Chrome Stop juggling three different tools. Full Page Screen Capture grabs any web page — the visible area, a custom cropped region, or the entire scrolling page from top to bottom — in one click, then hands you a full annotation editor to mark it up before you save, copy, or share it. No watermarks, no paid tier. THREE WAYS TO CAPTURE • Full Page Capture — Captures an entire web page, including everything below the fold, automatically scrolling and stitching it into one seamless image. Handles the tricky cases other extensions choke on: sticky headers and frozen table rows, lazy-loaded content, independently-scrolling panes (chat apps, dashboards), embedded Google Sheets, Microsoft Teams, and SharePoint/OneDrive documents — even wide content that needs to scroll sideways as well as down.

What it costs vs what you'd save

The starter prompt

Create a Chrome extension that captures full-page scrolling screenshots, visible area captures, and selected region captures. Implement an automatic scrolling content script that stitches viewport frames into a single image using an HTML5 canvas, handling fixed headers cleanly. Open the resulting image in a dedicated editor tab with basic annotation tools (arrows, text, rectangles, blur) and options to copy to clipboard or download as PNG/PDF.
