SuperScreenshot, a Snipping Tool alternative that scrolls
Built with Claude's help: drag a selection past the bottom of a window and the page scrolls under it, producing one stitched full-resolution image.

The full story
SuperScreenshot is a Snipping Tool alternative for Windows 10 and 11 that scrolls. Press Win+Shift+X, drag a box, and keep dragging past the bottom of the window: the page scrolls underneath, faster the further you push, and letting go puts one stitched full-resolution image on the clipboard.
It works from pixels rather than a page's HTML, so it works in any app that scrolls. Each frame it hashes rows of pixels to work out how far the content moved, leaves out rows that stay identical as sticky headers and footers, and for blurred or see-through headers takes each row from the frame where it sat nearest the middle of the window.
The maker built it with a lot of help from Claude. It is free and MIT-licensed, with no account or telemetry; the installer isn't code-signed yet.
