SeamShot
Full-page screenshots, seam-verified before stitching
Full-page screenshot tools usually break on tall pages — sticky headers get duplicated, seams line up wrong, stitches tear apart. SeamShot checks every overlapping region pixel by pixel before joining two slices, which is why long pages come out clean. It can also watch a page on a schedule, then show you a text-plus-image diff against your last capture — so changes surface on their own instead of you re-checking by hand. It's free and doesn't require an account.

Hey Product Hunt 👋 What inspired this: every full-page screenshot extension I tried had the same failure mode on tall pages — a sticky header duplicated three times down the image, or a seam line where two slices didn't quite line up. That's the actual bug I kept hunting down build after build. So instead of trusting scroll position, SeamShot pixel-checks each overlapping region before stitching two slices together. Along the way I ended up wanting two more things for my own use, so I built them in: watching a page on an interval and getting notified when it changes, and pulling a clean text + image diff against your last capture. Free, no account needed. Would love feedback — especially if you find a site where the stitch still breaks, that's the best kind of bug report for this project.
