The site shows where crimes have occurred in the city and police say if people know where crimes are occurring, they will be more likely to report suspicious activity.
The site is open to public with the option to submit anonymous tips.
Only five types of crimes will be listed initially: break-and-enters, robberies, thefts from vehicles, vehicle thefts and mischief.
The Saint John Police Force is the first agency in Atlantic Canada to use these tools.
