Feature Highlights โ€ข Auto-suggestions in dropdowns as you start typing. โ€ข Autofill any field using your context menu. โ€ข Add, edit, remove, and reorder your data as you wish. โ€ข Organize your data in folders. โ€ข All data is stored locally in your browser storage. โ€ข Import/export your data to a file.

Why Use SimpleFill โ€ข On average, it takes 12 seconds to type out a name, email, and address. With SimpleFill, it takes a maximum of 3 seconds. โ€ข The default browser autofill isn't accurate most of the time, and browsers don't allow you to edit the saved information. โ€ข Without SimpleFill, you can't fill out forms using your right-click context menu, which is super handy. โ€ข The default browser autofill do not work with large blocks of text, such as emails.

Getting Started โ€ข It's quite simple (no pun intended) to use SimpleFill. โ€ข Install the extension by clicking the 'Add to Chrome' button. โ€ข Right-click on any input field and select SimpleFill > Add form data... โ€ข Enter your details and click on the "Add" button. โ€ข As you type in any input field, SimpleFill will automatically suggest relevant entries. Alternatively, right-click on an input field and select your saved data directly from the SimpleFill context menu to instantly fill the form.

Possible disadvantages of CodePen

    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.

  • Dependence on Browser
    The functionality of SimpleFill is heavily reliant on browser compatibility, which may limit its effectiveness if there are updates or changes in browser technology.
