About InfiniPaint

InfiniPaint is an open-source drawing and note-taking app built on an infinite canvas that you can zoom without a fixed limit, until your computer runs out of memory. That makes it handy for sketches that mix huge scale differences, such as a solar system drawn to scale, as well as for ordinary notes and doodles.

Collaboration is built in through online lobbies, which include text chat and the ability to jump to the position of other participants. The project is written in C++ and has a web version compiled with Emscripten that needs a WebGL2-capable browser, though the maintainer recommends the native build for a better experience. Drawing tablets are among the topics the project lists.

Native builds are offered for Windows (installer or portable zip), macOS on Apple Silicon, and Linux through Flathub or flatpak bundles. Files use the .infpnt extension. The author says it was inspired by the Lorien infinite canvas program, and the code is released under the GPL-3.0 licence.
