If you've ever built a registration page, admin dashboard, CRM, student management system, or e-commerce checkout, you know one frustrating reality you spend far too much time typing the same fake information repeatedly.

Name...

Email...

Phone number...

Address...

Password...

Company...

And then you do it all over again for the next test.

After repeating this process countless times during development, I decided to build a better solution.

That's how AutoForm Fill – Fake Data Generator was born.

AutoForm Fill is a lightweight browser extension for Chrome and Firefox that fills almost any web form with realistic fake data in a single click. Everything happens locally inside your browser—no accounts, no cloud service, and no internet connection required after installation.

Whether you're a developer, QA engineer, web designer, student, or tester, this extension helps you eliminate repetitive data entry so you can focus on building and testing your applications instead.

Why I Built This Extension

As a web developer, I frequently work with:

Registration forms
Login pages
Admin dashboards
CRUD applications
Multi-step forms
Laravel projects
React applications
Vue dashboards
Testing environments

Every new feature meant filling the same form over and over again—sometimes dozens of times every hour.

Existing autofill extensions either required online accounts, generated unrealistic data, or failed to work with modern JavaScript frameworks.

I wanted something that simply worked, so I created AutoForm Fill – Fake Data Generator.

One Click. Every Field Filled.

The workflow is intentionally simple:

Open any web form.
Click Fill Form from the extension.
Watch every visible field populate automatically.

That's it. No configuration is required for most websites.

The extension intelligently understands what each field represents and inserts realistic fake information.

Smart Field Detection

One of the biggest challenges with automatic form filling is recognizing what each input actually represents.

Instead of relying only on the field name, AutoForm Fill analyzes multiple attributes simultaneously, including:

HTML input type
Autocomplete attributes
Labels
Placeholder text
Name attributes
ID values
ARIA labels
Accessibility metadata

This intelligent scoring system allows the extension to correctly identify fields even when websites use unconventional naming conventions.

Supports a Wide Variety of Form Fields

The extension automatically fills many common input types, including:

Full Name
First Name
Last Name
Email Address
Phone Number
Street Address
City
Company
Website URL
Password
Date
Numbers
National ID (NID)
Textareas
Dropdowns (Select)
Checkboxes
Radio Buttons
File Uploads

If a field isn't recognized, the extension handles it intelligently. Unknown text fields receive a simple placeholder like "Test", while unknown number fields receive a random value between 1 and 99.

Built for Modern Web Frameworks

Modern web applications rarely use plain HTML anymore. Many autofill extensions fail because JavaScript frameworks don't detect manually assigned values.

AutoForm Fill solves this by triggering native browser events after updating each field, ensuring framework compatibility. It works well with:

Plain HTML
React
Vue
Angular
Laravel Livewire
Filament
Material UI (MUI)
React Select
Ant Design
Select2

and many other modern UI libraries.

Dynamic Forms? No Problem.

Many applications allow users to dynamically add more fields, such as:

Add Another Student
Add More Products
Add Experience
Add Education
Add New Address

Normally, you'd need to click every Add More button before filling. AutoForm Fill can detect these buttons automatically and expands up to three additional rows before filling the new fields, dramatically speeding up testing of repeatable form sections.

Safe Form Filling

One concern with automatically filling forms is accidental submission. Imagine pressing Enter halfway through testing or clicking a button while the extension is still working.

To prevent this, AutoForm Fill temporarily blocks:

Form submission
form.submit()
Enter-key submission
Risky navigation clicks

Once filling finishes, everything returns to normal, making testing much safer.

Bangladesh-Friendly Fake Data

Unlike many autofill tools that only generate Western-style data, this extension also supports realistic Bangladeshi information, including:

Bengali-style names
Bangladeshi addresses
Local mobile numbers (01XXXXXXXXX)
International format (+880...)

You can even choose your preferred phone format inside Settings.

Create Your Own Custom Rules

Every project is different. Some websites use unusual field names like:

employee_code
student_roll
nickname
office_phone
emergency_contact

Instead of hoping the extension recognizes them, you can define your own mapping rules. For example:

nickname → Name
employee_id → Skip
customer_email → Email

Regular expressions are also supported. For example:

my_.*field → Email

You can even tell the extension to skip certain fields entirely.

Upload Custom Files Automatically

Testing file uploads usually means repeatedly selecting the same image or PDF. AutoForm Fill allows you to configure your own upload files, including:

Images
PDF files
Documents

This is especially useful for testing:

Profile photo uploads
Resume uploads
Document verification
Attachments

Flexible Settings

The extension includes a clean settings panel where you can customize nearly every behavior:

Enable or disable individual field types
Turn password filling on or off
Configure keyboard shortcuts
Choose phone number format
Manage upload files
Create custom rules

This flexibility allows the extension to adapt to almost any project.

Keyboard Shortcut Support

If you prefer keyboard-driven workflows, there's no need to open the popup.

Simply press Ctrl + Shift + V to instantly start filling the current page. The shortcut can also be disabled if you prefer, or customized in the settings.

Privacy Comes First

Privacy was one of my highest priorities while developing this extension.

AutoForm Fill does not:

Create an account
Require sign-in
Upload form data
Send information to any server
Track browsing activity
Store personal information online

Everything runs locally inside your browser. Your data never leaves your computer.

Designed for Developers

Internally, the extension is structured to remain easy to maintain and extend. The core filling engine lives inside content.js, with synchronized logic for both Chrome and Firefox versions.

The filling process includes:

Smart field detection
Dynamic section expansion
Form submission protection
Native event dispatching
Framework compatibility
Shadow DOM support

Settings are stored using browser storage APIs, allowing configuration to persist across sessions.

Typical Use Cases

AutoForm Fill is useful for many scenarios:

Web Developers

Quickly populate registration forms while building new features.

QA Engineers

Reduce repetitive testing during manual quality assurance.

UI Designers

Preview interfaces with realistic content instead of empty inputs.

Students

Test academic projects without manually entering fake information.

Freelancers

Save time while developing client dashboards.

Software Companies

Accelerate internal testing workflows.

Installation

Chrome

Open Chrome Extensions.
Enable Developer Mode.
Click Load Unpacked.
Select the Chrome extension folder.

Firefox

You can install the Firefox version directly from Mozilla Add-ons or load it temporarily for development through Firefox's debugging tools.

Open Source

I believe useful developer tools should be accessible to everyone. That's why AutoForm Fill is open source.

Developers are welcome to:

Inspect the code
Contribute improvements
Report issues
Suggest new features
Customize it for their own workflow

Whether you're using it for personal projects or commercial development, you're free to modify and extend it.

Future Plans

This project continues to evolve. Some features I plan to explore include:

AI-assisted field detection
Country-specific fake data generators
Faker profile presets
Team configuration sharing
Export and import settings
Improved multilingual support
Additional framework compatibility
Smarter validation-aware data generation

Community feedback will continue shaping future releases.
