Questions
Is SnapMark free?
Yes. It’s free and open source under the MIT license, with no account, no trial and no ads. The code is on GitHub, so anyone can read it, build it themselves or improve it.
Why does my Mac or PC warn me when I open it?
The app isn’t signed with a paid Apple or Microsoft certificate yet, so your system can’t check who made it. On a Mac, open it once, then go to System Settings → Privacy & Security and click Open Anyway. On Windows, click More info → Run anyway. If you’d rather not, you can build it yourself from the code on GitHub.
Does it upload my screenshots?
No. SnapMark has no network code at all: no uploads, no share links, no analytics. Your screenshots go to your clipboard or a folder you choose, and nowhere else. That’s on purpose, for screenshots of client work.
Why does it ask for Screen Recording on a Mac?
macOS asks that of every app that captures the screen. Allow it under System Settings → Privacy & Security → Screen & System Audio Recording, then quit and reopen SnapMark.
How is it different from Lightshot?
The capture works the same way: a hotkey freezes the screen, you drag a region and the tools appear next to it. SnapMark adds what design feedback needs: numbered steps with labels, measuring in px and pt, the HEX color under the cursor, cursor pointers, a spotlight, pins that float above your work, and shapes that stay editable until you copy. It isn’t made by or connected to Lightshot.
Does it work on Windows?
Yes, on Windows 10 and 11, with an installer and a portable version. It’s a beta: it’s used every day on a Mac, and the Windows build has had less real-world testing, so bug reports help a lot.
