Abstract: Vera C. Rubin Observatory, formerly known as the Large Synoptic Survey Telescope (LSST) is approaching its operational phase, and all actors in the scientific/software ecosystem surrounding it are in the last phases of preparations. One of the types of the data that Rubin will publicly deliver are real-time alerts - a data stream of transient astronomical events. These alerts will be disseminated to the public through seven project-approved 'community brokers' - applications used to ingest data stream and provide various additional functionalities. In this review paper we compare software designs and analyze features of seven Rubin community brokers - ALeRCE, AMPEL, ANTARES, Babamul, Fink, Lasair, Pitt-Google.
