UNPROTON makes small, dependable software for the work most tools overcomplicate.
We start from a simple idea: most software does too much. So we build the opposite — tools narrow enough to master in a minute, light enough to forget they're running, and honest enough to keep your data on your machine when it belongs there.
Three tools today, more on the way. Same name, same standards, same promise.
No account, no setup, no commitment. The whole point is that it just works.
