The internet is a vast ocean of billions of websites, each with its unique perks and appeal. But finding cool new sites can be a bit of a challenge, especially when you don’t know where to start. If you’ve been looking to explore new, interesting websites or are just bored, you’re in the right place. We’ve compiled a list of ten of the coolest websites to check out in 2025.

1. Outrider

If you’ve ever wondered what a nuclear blast might look like in your city, Outrider.org lets you simulate it.

While that might sound a little dark, it’s actually a fascinating educational tool. It helps you visualize the scale of destruction caused by nuclear bombs—from Little Boy (dropped on Hiroshima) to the Tsar Bomba, the largest nuke ever tested.

Visit the website, select your location and bomb type, choose whether you want a surface or air detonation, and then watch the simulation. The tool displays different impact zones, such as the fireball, radiation spread, and heat wave. It even estimates the total number of fatalities and injuries.

2. Ventusky

If you’re a weather nerd, Ventusky is hands-down the coolest weather site out there. Although it shows the same old metrics, it differentiates itself by displaying live wind patterns, air pressure changes, temperature gradients, and even precipitation animations over a stunning 3D map.

You can explore the globe, watch storm systems form in real time, and nerd out on the visuals.

4. MyRetroTVs

We can all agree that watching TV was one of the most fun activities in the past, thanks to all the iconic shows and cartoons. This feeling is pretty much gone thanks to streaming websites taking control of most of the content market.

MyRetroTVs brings it back. This site recreates the look and feel of old-school televisions—complete with knobs, static, and retro interfaces. You can explore vintage content by decade, from the 1950s to the 2000s. Just choose your favorite era, pick a genre, and enjoy your favorite childhood shows.

5. Scale of Universe

It’s no secret that the universe is insanely big—so big, in fact, that imagining our scale compared to a star is incomprehensible. That’s where the Scale of Universe website comes in. It lets you zoom in and out across the universe, from the tiniest quantum foam to massive galactic superclusters.

This interactive tool is a fantastic reminder of both how small we are compared to the universe and how large we are compared to an atom. You can even search for specific objects, species, or elements and click on them to learn more.

You can lock specific colors, adjust individual shades, export your palette as an SVG or PNG file, and browse trending palettes from other designers. It’s a super handy site that can help you speed up your creative process and spark inspiration when you’re stuck.
