Find a room. Find a roll. This is the crowdsourced directory of BJJ open mats across the U.S. — pick your metro and see every drop-in session by day and time. Gi and no-gi, all levels, team-verified.
Unstructured training time — no class, no curriculum. Just space to roll and drill. Many gyms welcome drop-in visitors from other academies; gi or no-gi depends on the session.
Pick your metro above. Each page lists every known open mat grouped by day and time, with the gym, gear, and skill level so you can just show up and train.
Open-mat times change constantly. This directory is crowdsourced and every submission is verified by our team before it goes live.
