Autofill forms with mock data for testing

Hacker News

I got tired of typing the same names, emails, and phone numbers again and again while building/testing forms — usually ending up with gibberish. So I built MockFill, a Chrome extension that auto-detects input fields and lets you autofill realistic mock data in one click (single field or entire form). It’s free, works locally, and doesn’t collect any data. Would love feedback from the HN community
