snapVector

Open-source Skitch alternative. Capture, annotate, and share — on macOS, Windows, and Linux.

What is snapVector?

snapVector is an open-source, cross-platform screenshot and vector annotation tool. Capture any region of your screen, draw arrows, highlights, and text with crisp vector shapes, then copy straight to the clipboard or export to PNG / SVG. Designed as a modern Skitch alternative that runs natively on macOS, Windows, and Linux.
