Gifcurry vs Gifsicle

Gifcurry is a free, open-source video editor for creating and editing GIFs on Linux and macOS. It accepts GIFs or videos and saves results as GIFs or videos. Both graphical and command-line interfaces are available. Editing controls cover cropping, trimming, seeking, duration and size changes, frame-rate settings, color-count adjustment, dithering, and subtitle import. Text overlays can be configured by font, size, color, position, outline, rotation, and timing. Linux installation options include an AppImage, prebuilt binaries, pacman, and snap; Mac installation instructions are provided in the project readme. Running it requires GTK+, GStreamer, FFmpeg, and ImageMagick. The maker says Windows will most likely work but has not tested it. The project began in 2016 and uses the BSD-3-Clause license. Suggested uses include GIFs for pull requests, README files, presentation slides, email replies, indie-game promotion, and custom Slack animated emoji.

Gifsicle is a free command-line tool for creating, editing, and inspecting GIF images and animations. It can combine GIF inputs into animations, set frame delays and looping, and extract, insert, replace, or delete frames. Image options include resizing, cropping, flipping, rotating, changing transparency, and reducing colors. Its animation optimizer offers three levels and stores changed portions of frames, though optimization can sometimes increase file size. Gifsicle can print detailed GIF information, including comments, and control interlacing, palettes, and transparency. Batch mode changes GIF files in place. The distribution also includes gifview, an animated-GIF viewer, and gifdiff, which compares GIFs for identical visual appearance. It is available for Linux, macOS, and Windows, with a source archive provided by the maker. Building it requires an ANSI C compiler. The manual notes that some Java and Internet Explorer versions may not display minimal optimized GIFs correctly; the careful option writes slightly larger files to avoid those compatibility problems.
