How they compare
Both belong to the BaDoink network, both add two or three VR scenes a week and both work with all the major headsets, so the choice comes down to style.
BaDoinkVR is the network's flagship. ThePornDB lists more than 1,090 scenes, and they're long, mostly 45 to 80 minutes, usually one performer in POV, with a consistent look from scene to scene.
RealVR has the bigger library, about 1,480 scenes, shot in 180-degree 3D in up to 8K at 60fps with binaural sound. It leans into passthrough (mixed reality) scenes made for Apple Vision Pro and Meta Quest, and more of its scenes have two performers. It also has free sample scenes to try first.
Neither shows prices before checkout, so compare the plans and what they renew at when you sign up.
