The Problem
Ever spent 20 minutes filling out a long form — job application, insurance quote, registration — and then the page crashes, your session expires, or you accidentally hit the back button?
All that data, gone. Browser autofill doesn't help because it only remembers basic fields like name and address, not the custom stuff you actually typed.
What I Built
FormVault is a Chrome extension that automatically saves everything you type into web forms, locally on your machine. If the page crashes or you navigate away, your data is still there when you come back.
Key details:
- Zero network requests — your form data never leaves your browser
- Auto-saves as you type, restores when you revisit the page
- Works on any form on any site
- One-click clear if you want to wipe saved data for a page
- Lightweight, no account needed, no permissions beyond the active tab
Why I Made It Privacy-First
Most form-saving tools sync your data to a cloud server. That means your half-finished job applications, medical forms, and financial info sits on someone else's infrastructure. I didn't want that.
FormVault uses chrome.storage.local exclusively. Nothing is transmitted. Nothing is stored externally. You own your data, period.
Try It / Give Feedback
I'm a cybersecurity student and this is one of my side projects. I'd genuinely appreciate feedback — especially on edge cases where form detection might break, or ideas for features that would make this more useful for your workflow.

What form-saving solutions do you currently use? Or do you just accept the risk and re-type everything?
