AGILE is an ASI (Italian Space Agency) Small Scientific Mission dedicated to high-energy astrophysics which was launched on April 23 2007 from Satish Dawan Space Centre (India) on a PSLV-C8 rocket. The AGILE Payload is composed of three instruments: a Tungsten-Silicon Tracker designed to detect and image photons in the 30 MeV-50 GeV energy band, an X-ray imager called SuperAGILE that works in the 18-60 keV energy band, and a Minicalorimeter that detects gamma-rays or particle energy deposits between 300~keV and 200~MeV. The instrument is surrounded by an anti-coincidence (AC) system to reject particle background. The Silicon Tracker and Minicalorimeter works in GRID mode, a photon-by-photon acqusition mode. We have developed a web-based software system for the monitoring and fast detection of gamma-ray transients detected by AGILE-GRID telescope. Each 90 minutes (the duration of the AGILE orbit) the data are acquired from satellite by the Ground Segment and sent to AGILE scientific team. We present the software designed and developed by the Agile Team to perform on the AGILE data the automatic analysis for detection and alerts on AGNs and galactic transients.
