4o4 — AsyncAergia

4o4 introduces a bit of creative chaos to your web browsing. Every time you click a link, there is a small chance (9%) that you will be redirected to a custom-designed, interactive "error" page instead of your intended destination.

While it works as a lighthearted prank, the heart of 4o4 is a community-driven gallery. Instead of a standard browser error, your "404" might be a retro terminal simulation, a 3D WebGL scene, or a glitchy CSS animation.

Key Features:

Unpredictable Browsing: A 9% chance to trigger a custom 404 page on any link click.
Community Gallery: A rotating showcase of creative "Not Found" pages built by developers from around the world.

Privacy First: 4o4 operates entirely locally on your device. It does not track your clicks, store your browsing history, or collect any analytics or personal data.


For Developers:
4o4 doubles as an open-source creative sandbox! If you want to practice your frontend skills by building a unique 404 page (using any framework or library), you can contribute directly to our GitHub repository and have your work featured in the extension's rotation.
