Astronomical Object Classification ML Frameworks

Tools for classifying celestial objects (stars, galaxies, quasars) using spectral, photometric, or morphological data from astronomical surveys. Does NOT include general image classification, distance/redshift estimation without classification, or non-astronomical entity classification.

There are 62 astronomical object classification frameworks tracked. 3 score above 50 (established tier). The highest-rated is skyportal/skyportal at 68/100 with 125 stars and 18 monthly downloads.
