BigChange Lightning adds AI tools for business questions, engineer training, job preparation and documentation, customer summaries, messaging, and GPS time tracking.

CrowdCAD is a free, open-source dispatch platform for standby medical operations at events. Teams can create incidents, assign personnel, and track status updates. Its dashboard brings active incidents, team locations and statuses, and clinic capacities into one view. Responsive web access lets field supervisors review and update dispatch data from mobile devices, and saved venue templates support recurring events. Lite Mode provides the core workflow but excludes shared events, multiple dispatchers, venue maps, custom venues, and interface customization; administrative control is limited, and CrowdCAD server-side storage is not used. Self-hosting adds shared operations, multiple dispatchers, maps, custom venues, interface customization, and organization-managed administration. Supported backends include Firebase and PocketBase, including PocketBase on local or LAN infrastructure. Organizations managing a self-hosted deployment are responsible for authentication, access controls, backups, retention, monitoring, patching, and incident response. The guide notes that PocketBase self-hosting is not itself a substitute for a signed HIPAA BAA.
