Let’s Ninja is an information portal dedicated to ninja sport and the community around it. The sport combines hanging, climbing, swinging, balancing and moving through challenging obstacle courses, and has grown in popularity in Germany alongside the television show Ninja Warrior Germany. The site brings together practical resources for newcomers and information for experienced athletes, fans and event organizers.

Its Ninja School offers tutorials, tips and guidance from athletes and experts to help visitors prepare for training in a ninja gym and for their first competition. A directory helps users find ninja gyms and other places to practise. The portal also publishes athlete rankings based on results from competitions following IGN standards, alongside a Hall of Fame and earlier ranking lists. Visitors can explore the Ninja-Bundesliga, find community competitions and events in a calendar, and learn about the German Ninja Sport Association and its work in sport development and quality. Athletes competing in events such as the Bundesliga can obtain a free Lets.Ninja-ID, providing a personal digital profile.
