Particle acceleration to relativistic energies is common in the Universe. A wealth of astrophysical accelerators have been identified over the past decades using gamma-ray observations. Particularly interesting are time variable sources, where the acceleration and radiation processes can be observed over time. Recently, the LAT collaboration has published a second catalog of flaring gamma-ray sources (2FAV). The catalog is based on 7.4 years of observations, during which 518 flaring sources where detected on weekly time scales. Out of these, 77 had not been seen in gamma-rays before. In addition, the catalog pipeline is used to analyse LAT data in real time. The results are made public on an interactive web page. In this presentation, I will review the different classes of variable gamma-ray sources based on the 2FAV and give an outlook on future developments.
