MythLayer

MythLayer is a lightweight battlemap effects overlay for D&D and tabletop RPGs, built for physical tables using TVs, projectors, or table-mounted displays.

Run a video battlemap, launch MythLayer on top, then right-click to place animated spell effects, 5e area templates, measurements, scene tints, grid overlays, objects, and dice rolls directly over the map.

It is one HTML file: no install, no accounts, no internet, no tracking, and no subscription.

MythLayer is made for DMs who use real minis, physical terrain, and shared screens but still want the visual punch of a VTT. Calibrate the map, drop in fireballs, cones, cylinders, darkness, rough terrain, spell circles, dice, and more.

The map stays the map. The minis stay minis. The magic goes on top.
