Lumi-o is a Linux-only, dedicated layered raster painting application focused on stability, responsiveness, and a streamlined illustration workflow.
Built on GIMP’s core architecture, it prioritises painting performance, reliable autosaving, rolling incremental saves, and support for massive canvases through lazy loading.
Wacom tablet support has been extensively tested for smooth, responsive input.
Developed on Debian 13 with the Cinnamon desktop environment.
After a long period of development and testing, Lumi-o is now approaching its first beta release. Most major design and architectural decisions are already in place, with the remaining work focused mainly on polishing and bug fixing. Any testing and feedback is greatly appreciated. An AppImage build is available alongside the full source code.
