What this builder is for
Sketch custom islands, training spots, or guide overlays in an OSRS terrain palette — water, grass, desert, lava, and the usual map icons (bank, mine, fishing, altar). Export a PNG for Discord/guides or save JSON to keep editing. For the real Gielinor map with game coordinates, use the interactive world map.
Quick start
- Pick a preset size (or set W/H), then choose a terrain swatch.
- Brush / Fill / Rect to paint land and water. Place map icons for banks and skilling spots.
- Export PNG when you are done, or Save JSON to reopen later.
