OpenMapp Launches Free Map for BJJ Gyms in 600 US Cities

OpenMapp, a free map of Brazilian jiu-jitsu (BJJ) gyms, has launched a comprehensive database covering more than 600 US cities. The platform, available at [www.openmapp.com], provides detailed information on weekly class and open mat times, drop-in policies, and visitor fees for BJJ gyms across the country.

Founded in Monterey, California, in 2026, OpenMapp aims to simplify the process of finding a BJJ gym for practitioners traveling to new cities. The website allows users to search by city, neighborhood, or ZIP code and filter results based on whether a gym welcomes drop-ins, offers Gi or No-Gi classes, or has an open mat. Each listing is re-checked against the gym's published timetable every month to ensure accuracy.

Harry Burman, the founder of OpenMapp, explained the motivation behind the platform.

The platform currently lists 35 gyms in San Diego and Las Vegas, with these two cities following closely behind Houston, Austin, and Phoenix. Each city has its own dedicated page, such as the BJJ gyms in San Diego, which can be accessed at [www.openmapp.com/bjj/san-diego].

For gyms that accept drop-in reservations through OpenMapp, the service is free until January 1, 2027. Users can sign the gym's waiver and pay for a drop-in session directly through the platform. OpenMapp also integrates with AI assistants, allowing users to look up listings through its Model Context Protocol (MCP) server.

Traveling BJJ practitioners can now easily find the information they need to train in a new city. With OpenMapp, they can avoid the hassle of searching for open mats and drop-in policies on multiple platforms. The platform's user-friendly interface and regular updates ensure that users always have the most current information.

In addition to its primary function, OpenMapp also highlights the growing demand for BJJ training across the United States. The platform's success underscores the increasing popularity of BJJ as a sport and a fitness activity.
