We build local-first software with privacy by default โ tools that run close to your machine, minimize data exposure, and stay practical for real-world use.
Software should be local-first and self-contained: ideally a single executable, or one straightforward installer when needed, with dependencies kept minimal.
If an installer is required, it should install the minimum necessary and ensure 'uninstall' actually undoes everything. No traces of the software left behind.
We design for minimal data exposure: local-first behavior, clear boundaries, and sensible defaults that donโt require accounts, tracking, or unnecessary network access.
If AI is used, it runs locally by default. Cloud AI is only used when you explicitly configure it.
