Partyhatify is a free Chrome extension developed by Xan that adds a playful twist to your browsing experience. With Partyhatify, you can easily add party hats to any webpage, giving it a festive and fun look.

Inspired by the party hat meme from Tom Siddell's webcomic "Gunnerkrigg Court," this extension brings a touch of whimsy to your online activities. Whether you're browsing news articles, shopping websites, or social media platforms, Partyhatify allows you to inject a bit of celebration into your webpages.

While Partyhatify works consistently on most websites, it does have some known issues with certain webpages. However, the developer is actively working on improving the extension and has plans to introduce more features in future updates.
