Apps and open-source infrastructure
Dizitart builds Kruftle, a free and open-source disk cleaner for developers, and Spoolnote, a privacy-first voice notes app, alongside a portfolio of open-source infrastructure — embedded databases, Flutter libraries, and developer tooling.

A small, focused set of apps. Kruftle is free and open source; Spoolnote is free to use with an optional paid upgrade. Each has its own page covering what it does, its current status, and where to follow along.
