CAT-UXO is an online resource and community platform focused on unexploded ordnance (UXO) and other explosive hazards. Its stated aim is to bring together the Explosive Ordnance Disposal (EOD) community to share information and increase awareness of hazards found around the world. The site provides a searchable hazard database and organizes information across categories including landmines, submunitions, grenades, aircraft bombs, rockets, missiles, mortars, projectiles, fuzes, naval devices, small arms and light weapons, and improvised explosive devices.

Users can also explore IED incidents and terrorist groups. EOD professionals and people with a technical interest in explosive hazards can become members to access additional technical information and downloadable data. CAT-UXO also offers online lessons covering EOD doctrine, with courses described as Levels 1 to 3 and certificates intended to confirm technical knowledge and competence.

The platform invites users to contribute and provides information for organisations, commercial members, and advertisers. Its message emphasizes shared knowledge as a way to help save lives
