Flameshot vs ShareX

Flameshot is free, open-source screenshot software for Linux, macOS, and Windows. Its workflow is to select part of the screen, add annotations if needed, and save the image to a computer. Editing tools include arrows, text, highlighting, drawing, shapes, counters, solid color boxes, and blur or pixelation. Users can customize the interface color, button selection, keyboard shortcuts, and image-saving behavior. Export formats include PNG, TIFF, WebP, and additional Qt image formats. The command-line interface can run commands without opening the graphical interface and supports scripting and key bindings. Flameshot can upload images to Imgur, alerts users before upload, and allows deletion afterward. The project warns that an uploaded image is no longer under the user's control and recommends pixelation or a filled rectangle rather than blur for privacy protection. Downloads include 64-bit Windows installer and portable versions, macOS installation through Homebrew or a DMG, and Linux AppImage, package manager, Snapcraft, or Flathub options. Official documentation covers installation, troubleshooting, configuration, platform help, command-line options, and privacy.

ShareX is a free, open-source screenshot and screen-recording tool for Windows. It captures the full screen, a selected region, the active window, a scrolling page, or a monitor, and can record video and GIFs. Its image editor provides annotation and redaction tools, while OCR recognizes text in images. After a capture, ShareX can copy, open, shorten, or share links, and supports many upload destinations as well as custom uploaders. It also lists browser extension support and supports many languages, including English, Hindi, and Spanish. ShareX requires no account and has no advertisements. The ShareX Team maintains the software, which has had more than 18 years of active development and over 33 million downloads worldwide. The maker describes its approach as privacy first. The website provides documentation guides and links to related GitHub projects. ShareX is available for Windows.
