Show HN: I Built an Extension to Copy, Paste & Autofill Web Forms Instantly

Hi all! Hope you're all doing well!

I built MultiField CopyCat, a Chrome extension that helps you bulk copy, paste, and autofill multiple web form fields all at once. If you often find yourself retyping or copying form data field by field, this tool might save you time and frustration.

Website: https://multifield-copycat.com/

Quick Youtube demo: https://youtu.be/gi-lKZbawSk

Key features:

- Copy multiple form fields in selected area in one go

- Paste copied data back into the same forms in one go

- Copy & paste all form data from one page to another

- Save autofill settings for recurring use

- Supports common input types like text, checkboxes, radio buttons

- Customizable keyboard shortcuts for quick workflow

I've built this because, as a web developer, I often found myself copying form data between environments, e.g. from local to staging, or staging to live sites. I also test forms during development, so I added the instant autofill feature as well to make it a complete tool for forms. You can also enable/disable the autofill easily via the extension popup as needed.

This is my first time building an extension, so I'm sure there're plenty of room for improvement — feedbacks and suggestions are all very welcome!

You can check it out on the Chrome Web Store here: https://chromewebstore.google.com/detail/alglchohmdikgdjhafi...

Thank you so much for your time & for checking this out! Hope this helps you too!

And thank you WXT team for the amazing extension framework!

P.S. It probably sounds stupid: I did use my extension's autofill to save my draft post under https://news.ycombinator.com/submit, but hey it works lol
