Cosmik is a free, no-login web app that tracks the ISS, Starlink and over 20,000 satellites live in 3D, shows the real-time rocket launch schedule, and sends alerts so you know exactly when to look up. It runs entirely in your browser.

Yes. Cosmik is completely free with no login required. Optional push and email alerts are also free; the project is supported by donations.

How do I track the ISS with Cosmik?

Open Cosmik, search for the ISS (or any satellite), and follow it. Cosmik computes the next visible pass over your location and can send a push or email alert a few minutes before it flies over so you can step outside and watch.

Does Cosmik track rocket launches?

Yes. Cosmik shows the live upcoming launch schedule with countdowns, status, and embedded webcasts, and can alert you before liftoff for launches you follow.

How accurate is Cosmik's satellite tracking?

Cosmik propagates official CelesTrak orbital data (TLEs) with the SGP4 model in your browser — the same physics professional trackers use — for accurate real-time positions and pass predictions.
