QuickForm vs MockFill: which autofill extension do you actually need?

Key Takeaways

• MockFill auto-generates random fake data, ideal for first-run QA testing of form validation.
• QuickForm saves and replays real data, same values every time, across every device.
• QA teams spend 5 to 15 hours per week per tester on test-data setup and 82% still rely on manual testing (Katalon, Test Automation Statistics and Trends for 2025). Real-profile replay cuts that overhead.
• The average flow runs 11.3 fields across 5.1 steps (Baymard Institute, Checkout Flow Average Form Fields, 2024).
• Use MockFill if you need random fake data to test a brand-new form. Use QuickForm if you fill the same form with the same real data repeatedly: QA regression, job applications, or data entry.

Feature comparison at a glance

What is MockFill actually good at?

MockFill does one thing well: it generates realistic-looking fake data with zero configuration. Click the button, and fields fill with randomised names, email addresses, and phone numbers. That is genuinely useful when a developer or QA engineer needs to verify that a brand-new form accepts input and renders validation errors correctly, without caring what the actual values are.

MockFill's random-data model is a deliberate design choice, not a limitation. When your goal is exploratory testing across many data shapes, predictability is a problem. That is the one scenario where MockFill has an edge. Beyond that narrow window, MockFill offers no profile saving, no device sync, and no support for React or Angular forms.

Why does QuickForm matter for QA regression work?

QA teams spend 5 to 15 hours per week per tester on test-data setup, and 82% still rely on manual testing (Katalon, Test Automation Statistics and Trends for 2025). That overhead is what QuickForm targets: it saves and replays real profile data, the same values every time, across every device. How an autofill extension for QA engineers slots into a regression workflow is covered in detail there.

In 2024, the average flow runs 11.3 fields across 5.1 steps (Baymard Institute, Checkout Flow Average Form Fields, 2024). For anyone running regression tests or entering data into internal tools repeatedly, that is a meaningful amount of typing to eliminate. Unlike MockFill, QuickForm handles React, Angular, and Vue forms by dispatching native browser events, which is why the best autofill extension for React comparison is relevant here too: validation logic triggers and submit buttons enable correctly.

How do they compare on a checkout form you run 30 times a day?

This is the scenario where the difference is clearest. MockFill fills fields with random data you cannot reuse, so every regression run produces different values and you cannot compare results across runs. With QuickForm, you enable Record Mode, fill the form once with your standard test dataset, save the profile, and replay it in one click: same values, same sequence, every time.

QuickForm vs MockFill: which should you use?

For most users filling dynamic forms repeatedly, especially on React, Angular, or Vue apps, QuickForm is the better choice. It requires no configuration, syncs across devices, and handles the event-firing that modern frameworks require.

If you specifically need auto-generated realistic fake data with zero setup for first-run validation testing, MockFill fits that narrow use case. Otherwise, QuickForm's 60-second setup and free tier make it worth switching.

Frequently asked questions

Is QuickForm better than MockFill?

It depends on your use case. Use MockFill if you need random fake data to test form validation on a brand-new form. Use QuickForm if you fill the same form with the same real data repeatedly: QA regression, job applications, or data entry.

Does QuickForm work on React and Angular forms?

Yes. QuickForm dispatches native browser events after filling fields, so React, Angular, and Vue form state updates correctly. Most other extensions set DOM values directly without firing the events these frameworks need.

How is QuickForm different from MockFill?

The key difference: saving and replaying real profile data, same values every time, across devices. MockFill is stronger at auto-generating realistic fake test data with zero setup for first-run exploratory testing.

Can I switch from MockFill to QuickForm quickly?

Yes. The fastest path is to recreate your most repeated workflow with QuickForm's Record Mode. Fill the form once, save the profile, and compare it against your existing MockFill setup on the next real fill.
