RayMol

RayMol brings high-quality molecular visualization to macOS, iPad, and iPhone — built on the trusted PyMOL engine with a modern, native Metal renderer.

Load a structure from a file or fetch any entry from the Protein Data Bank, then explore it with smooth, real-time graphics:

• Representations — cartoon, sticks, spheres, surface, mesh, ribbon, dots, and labels. • Real-time quality — analytic ray-cast spheres and sticks, smooth tessellated cartoons, anti-aliasing, ambient occlusion, real-time shadows, and order-independent transparency. • Hardware ray tracing — on Apple-silicon GPUs, add ray-traced ambient occlusion and shadows live, and export crisp high-resolution images. • Themes — Classic, Paper, Sunset, or Dawn, or design your own with the live Theme Studio. • Sequence, selections, and measurements — a synced sequence viewer, named selections, and interactive distance/angle/dihedral tools. • Movies — build and export camera, scene, and state animations. • Scripting — the full PyMOL command interface for power users.

RayMol runs entirely on your device. It collects no personal data and includes no tracking or ads.
