Overhead (overheadexplorer.com) — a free, no-signup live flight radar and real-time night sky map, with 3D simulators and aviation/space news, all in your browser.

Overhead (overheadexplorer.com) is a free site where you can track what’s above you, without needing to sign up. It has two sections. The aviation section provides a live flight radar that uses public ADS-B data. You can click on any aircraft to view its route. Then, you can click its type to see a profile that includes the manufacturer, registration, and a basic safety note. This section also includes aviation news and airshow listings. The astronautics section features a real-time night sky map. It also has an AR camera mode for mobile devices, space news, and information on upcoming launches and meteor showers. Both sections include an interactive 3D simulator. The site is simple, without a backend, user accounts, or ads; everything operates directly in your browser.

Really cool that it's free and needs no signup, the 3D simulators were a nice surprise. One thing I'd love to see is a track-compare feature where you can pick two flights side by side and watch their paths and altitudes together, would make spotting crossing routes way more fun and actually useful for aviation nerds like me.
