Snapstack: Screenshots that expire unless you keep one

Hey Product Hunt, I built Snapstack because Mac screenshots give you a bad choice. ⌘⇧4 saves a file, and a year of that gave me 758 screenshots on the Desktop with the useful ones buried in the junk. ⌃⌘⇧4 copies to the clipboard instead, but one at a time, so three screenshots for one message means three rounds of take and paste. I even wrote a clipboard manager to fix the paste side, and it did. It did nothing for finding the screenshot I needed a week later. Snapstack is a menu bar app that fixes both. Take as many screenshots as you need with ⌘⇧1 or ⌘⇧2. They collect in a small tray instead of on your Desktop. One ⌘V pastes all of them at once, in the order you took them. At the end of the day (by default), anything you did not save deletes itself. Hit Save on one and it goes to a Keeps folder that never expires. Screenshots that belong together, like references for one project, get dropped onto each other on Canvas to make a named stack, and the stack stays. It is for anyone who screenshots to explain something, not to archive it. Developers pasting into Claude Code or Codex, designers collecting references, anyone reporting a bug. One payment of $9.99, lifetime license, free updates. macOS 13 or later. Nothing leaves your Mac. I would love to hear how you deal with screenshots today, and what you would want Snapstack to do next.
