Ksnip vs Markup Hero

Ksnip is a free GPL-3.0 screenshot tool for Linux, macOS, and Windows. It captures selected rectangles, the last selected rectangle, screens, all screens, or supported focused and cursor-under windows. Annotation tools include pen, marker, shapes, text, stickers, cropping, blur, pixelation, image effects, and watermarks. Screenshots can be uploaded to Imgur, FTP, or custom scripts, and exported as BMP, GIF, JPEG, JPG, PNG, PDF, or PS. Command-line capture can save to a chosen default location, filename, and format. OCR text extraction uses a separately installed Tesseract plugin on Windows and Linux/Unix. Downloads include packages such as RPM, DEB, APT, Snap, Flatpak, and AppImage, alongside Windows and macOS packages. Global hotkeys are documented only for Windows and X11, not Wayland. The project notes other macOS and Wayland limitations and says development capacity is limited.

Markup Hero creates annotated markups from screenshots, uploaded or pasted images and PDFs, blank canvases, or captures made with its Chrome extension. It runs on Mac, Windows, and Chrome, with scrolling capture, annotation tools, OCR, and cloud sharing. Markups can be exported as JPG, PNG, or PDF. The free Hero plan includes all product features, up to 25 markups, and 24 hours of editing for each free-plan markup. An account is required after five markups; the stated reasons are linking files to users and providing customer support. Super Hero offers unlimited markups, editing, and saving. Premium Monthly is $5 a month, while Premium Annual is $3 a month billed annually; those listings include unlimited markups and permanent editing history. Super Hero Monthly is $5 a month, and Super Hero Annual is $3 a month billed annually. Team and lifetime plans are also listed, with no prices specified.
