Every tracked satellite, about 16,000 of them, moving live around a 3D Earth on your Mac. Click any satellite to follow it and open the inspector: who flies it, when it launched, and its orbit. Travel the Space Timeline back to Sputnik in 1957 and watch the sky fill up. It runs in your terminal, too: start SatRadar in your terminal and the same Metal renderer streams every frame straight in. It works in most terminals: images where the terminal can draw them, the live globe as text elsewhere. One purchase. No subscription, no account, no ads. THE WHOLE SKY, NAMED The ISS and Tiangong with people aboard. Every Starlink shell. The GPS, GLONASS, Galileo and BeiDou fleets 20,000 km up. Weather satellites parked over the equator, 36,000 km out. Every dot has a name, an owner and a job, and SatRadar shows where it actually is right now. Positions are computed with SGP4 from the same orbital elements (TLEs) NORAD publishes, delivered from our own mirror and refreshed every six hours. ON YOUR MAC • Hover any dot to see what it is; click to follow it, with a live card for altitude and speed • The inspector: owner, launch site and year, apogee, perigee, period and inclination • The Space Timeline jumps to the moments that filled the sky: Sputnik, Gagarin, GPS, the ISS, the first Starlink shells • Search by name, NORAD ID, or a year from 1957 to 2037 • Play the History of Space: a guided walk from Sputnik in 1957 to today, era by era • Speed time up, or snap back to live • Day and night drawn live across the globe, with moving clouds, country borders and a lat/lon grid • Save a screenshot of any view IN YOUR TERMINAL • It opens with the satellite rain: every shell falls into orbit, then the camera pulls back to the whole swarm • Drag or use the arrow keys to orbit, scroll to zoom, hover for names • Click any satellite to follow it, with a live altitude and speed card • Tab tours notable satellites: the ISS, Tiangong, Hubble, each Starlink shell, GPS, geostationary • / searches by name or NORAD ID • Time warp from 1× to 1000×, and jump back through the eras to Sputnik • An FPS counter, because it is a terminal • Terminals without the Kitty graphics protocol get the live globe drawn in text characters, plus a pointer to Ghostty Terminal mode is not a port or a recording. It runs the Mac app's own renderer, frame by frame, and hands each frame to the terminal as an image. Look up. The sky is busier than you think.
