About

Cachecker: Last Modification Checker

Cachecker is a browser extension designed specifically for developers. With its sleek, modern interface featuring a bold red and black design, Cachecker lets you quickly verify the last modification time of any webpage by reading the server's Last-Modified header.

Key Features:

Real-Time Display:
Instantly view the elapsed time since the last modification of the page. This helps you identify whether your browser is showing an outdated version of your site.

Simplified Cache Diagnostics:
If your recent changes are not being reflected, Cachecker alerts you by highlighting the difference between the deployed version and the one currently displayed—prompting you to clear your cache for the latest update.

Minimalist, Intuitive Interface:
The extension's clean design and clear red and black aesthetics offer a user-friendly experience that seamlessly integrates into your development workflow.

Why Choose Cachecker?

Whether you're working in a development environment or monitoring a live site, Cachecker saves you time by eliminating confusion over caching issues. By providing precise information on the page's last update, it helps you focus on what matters most: developing and maintaining your projects.
