24 alternatives to FillApp

I built a free Chrome extension called FillApp. It lets you fill web forms just by writing plain text like: “Ship it from @NorthDelivery to @WestflowLimited” It parses the form automatically and fills it with the right data, including tricky fields like dates, multiselects, etc. You can also save and reuse snippets across different forms. It’s completely free and works with most modern web forms. Would love to hear what you think.

    Mock Fill▲13

    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
