AGILE is an Italian Space Agency (ASI)
scientific mission with INAF and INFN participation devoted to high-energy astrophysics.
We review here the AGILE contribution to the knowledge of gamma-ray bursts (GRB), but also other bursting events such as Terrestrial gamma-ray flashes (TGF) and Solar flares.
We also report the main results on follow-up observations of gravitational wave (GW) events, cosmic neutrinos and fast radio bursts (FRB),obtained thanks to the AGILE efficient and fast real-time analysis system.
AGILE real-time searches were performed with dedicated automatic pipelines, using data from all payload instruments: GRID (30 MeV - 30 GeV), MCAL (350 keV - 100 MeV)
and the Anticoincidence system (50-200 keV).
