About Grainbox

Grainbox Limited is a small software company in Aotearoa New Zealand. We make tools for developers, like evals-lab and Mobile Dev Browser, and simple apps for everyday life, like Turnsies and Plansies.

Most of what we build starts as something we needed ourselves. A prompt that behaved differently on a phone. A console we couldn't see. A household argument about whose turn it was. We build the fix, use it until it's right, and then share it.

We keep our products small and our data collection smaller. Where something can run on your own device, it does.
