ImageTagger is an open-source online platform where multiple people can label images together. It was built by Bit-Bots, the robot soccer team of Bielefeld University in Germany, to produce training data. As a Django-based web service, it lets you upload image sets, add annotations such as bounding boxes or polygons, verify them, and export them in various formats. Team-level permission management and annotation review features make it suited to collaborative work.
