LibreSprite

Originally created as a fork of Aseprite, LibreSprite is currently developed independently of its inspiration project, providing users with an open-source tool for creating sprites and animations. Whether you need to create pixel art for a 2D game or just for entertainment, this application can help you obtain real-time animations using an editor that offers an overall pleasant experience.

LibreSprite allows you to import sprite sheets to get started, but it is also possible to create a new project from scratch. It allows you to work on multiple projects at the same time, opening each in a separate tab.

The application provides support for both layers and frames, which offers better control over all the elements of the animation. You are free to alter a frame's duration and change the overall frame rate if necessary. The resulting animation can be previewed in real time

The main preview area, where all the editing takes place, is split into tiles, which allows you to draw patterns and textures much easier.

Its editing toolbox is available in a panel to the right of the main window, while additional options to manipulate the design are to be found in the application’s menus. Regular tools are available, such as marquee, a pencil and an eraser, a bucket tool to fill up shapes or an eyedropper for picking up colors. You can easily and precisely draw contours and enjoy the pixel-precise line and rectangle tools. Elements that you don’t need visible can be blurred, while zooming in or out if needed.

There are ready-to-use color palettes, but you can also create your own and have all the hues you use frequently in a design at your fingertips.

LibreSprite is an interesting app to have around if you plan on working on a 2D animation. It brings to the table a feature set ready to provide the tools needed to create appealing designs, while allowing you to focus on your design without being overwhelmed.
