Built Because We Needed These

SoftDZ started with a defect rate calculator we built for a QA report. Then an email signature generator because Outlook's built-in one is terrible. Then it grew from there.

Everything runs in your browser—we don't collect what you type into the calculators, don't require accounts, and don't nag you to upgrade to Pro. The tools just work.

We also write guides when there's something worth explaining properly (like how to verify file checksums without installing sketchy software). It's a small site, but everything here serves a purpose.
