Instantly autofill forms with mock data for testing

Tired of typing the same data again & again? Mock Fill is a Chrome extension that auto-detects inputs and lets you fill single fields or entire forms with realistic test data — all in one click. Saves devs & QA hours during testing.




Hi folks,
I built Mock Fill because I was frustrated with constantly retyping form data while testing and developing forms. Most of the time I ended up entering gibberish just to get through it. It was boring, repetitive, and slowed me down.
Mock Fill fixes this by auto-detecting form fields and adding a ✨ icon — click once and get realistic mock data instantly. You can fill a single field or the entire form in seconds with a keyboard shortcut as well.
🔒 No tracking, no data collection, everything works locally in your browser.
It's already saving me time in my own work and keeping me focused on the actual feature building.
I’d love feedback from fellow makers, devs, and QA testers — what would make this even more useful in your workflow?

Congrats on launching Mock Fill! This feels like such a simple but huge time-saver for anyone testing forms. Do you have plans to let people customize the type of mock data it generates?
