Krita vs MyPaint Brushes

Krita is free, open-source software for digital painting and artwork creation, with tools for illustration and 2D animation. Its brush collection includes more than 100 preloaded options and over nine engines for customizing brushes. Animation tools support audio, onion skinning, extensive timeline frames, and export to video or still images. For color workflows, Krita supports ICC management through LCMS, OpenColorIO for EXR, HDR painting, and OpenEXR. It can open and save PSD files and uses SVG for vector work. C++ and Python plugins can extend the application; plugins distributed for Krita must use the GNU GPL, though creators may charge for downloads. Krita lists Windows, macOS, Linux, and Android, but not iPads or iPhones. The maker says no registration or internet connection is required for use. The listed minimum RAM is 4 GB, with 16 GB recommended. Krita is free and open source, with no subscriptions or trials.

MyPaint Brushes is a free downloadable brush-data package for MyPaint and other applications that use libmypaint. The master branch contains brushes intended for libmypaint 2.x. For libmypaint versions below 1.5, the project recommends using the v1.3.x branch or a v1.x release instead; listed releases include v1.3.1 for libmypaint 1.3 or later and v2.0.2 for libmypaint 1.5 or later. The brush files use the .myb format, and commercial use is permitted. Application developers can locate the brush directory through pkg-config: C and C++ programs use the MYPAINT_BRUSHES_DIR macro, while other languages can use the brushesdir variable. Building and installing the package uses autogen.sh, configure, make, and make install. Historical SCons scripts are included for SCons 2.x, but do not work with SCons 3. The official brush data uses public domain or CC0 1.0 licensing. Installation scripts and other non-brush-data components use GPL-2+ licensing. The v2.0.2 release note says its changes reduce preview icon file sizes and that v2.0.x brushes generally need libmypaint 1.5 or later to work correctly.
