Aseprite is an animated sprite editor and pixel-art tool for game developers and pixel artists. It offers layers, frames and cels, frame tags with looping modes, onion skinning, palette editing, pixel-perfect strokes, tiled mode and custom brushes. Work can be exported as PNG sequences, animated GIFs, sprite sheets with JSON data and texture atlases, and a command-line interface supports asset pipelines. It is a desktop application for Windows, macOS and Linux, sold through its own website, Steam and itch.io, with a trial version.
Aseprite is developed by Igara Studio S.A., an Argentine company, so the vendor sits outside the EU. The source code is public on GitHub, but an end-user licence agreement allows compiling it for personal use only and forbids redistribution, so it is source-available rather than open source. The program runs locally. According to its privacy policy, the website runs on Google Cloud servers in the United States, with backups in the European Union, and purchases are handled by the store used, such as Steam or itch.io.
