Hi, I made StarLeak because I wanted to know which Starlink satellites are actually overhead where I live. It pulls orbital data from CelesTrak and computes positions client-side in the browser (elevation/azimuth/range), estimates Doppler shift, shows a map with sunlit/eclipsed status, has a naked-eye visibility filter with optional notifications, and can export the next visible pass as an .ics calendar file. Free, no account needed: https://starleak.london.li/
Known limitation: accuracy depends on how fresh the orbital elements are (shown in the page header), so treat predictions as approximate, especially for objects re-entering or maneuvering.
