Hi Product Hunt! @ext_ian and I built EXT because we were frustrated with how challenging it was to build cross-platform desktop apps. Even with Electron, you still have to set up your own build pipelines, updating mechanisms, code-signing, deployments, and deal with cross-platform compatibility issues. We built EXT to make building cross-platform desktop software easier. Dog-fooding our own APIs, we ported 36 initial games and utilities to the EXT store, and we’ve open-sourced all of them here: https://github.com/extpkg If you’re into casual web games or want to check out some fun and useful utilities like JS Paint (inspired by ‘95 MS Paint), check out EXT! Features of EXT - All extensions work offline (we call apps on the platform “EXTensions” 🥁). - Once installed, extensions load instantly. - All extensions are available on Mac, Windows and Linux. - There are a variety of games including platformers, strategy games, puzzle games, and more… - All the extensions currently available are free!
