Guardi.space is a free and open web tool that tracks and forecasts satellite collision risks — designed mainly for CubeSats, smallsats, and academic missions. It uses public TLE data and SGP4 modeling to detect potential conjunctions up to 14 days ahead. The platform updates every 6 hours, assigns basic risk levels (High/Medium), and lets users follow specific satellites to get alerts. No login or payment required. Guardi.space was built as a lightweight utility for small teams that need situational awareness without enterprise software.
