Good to know
Everything about how Mosaic works, what it makes, and how it fits your engine.
Not to get started. You label what each tile represents (ground, platform, prop…) and Mosaic infers corners, caps, edges, fill and spacing for you. If you want to learn the underlying tile logic, the generated maps are a great, hands-on way to see it in action — but you'll never be blocked waiting to.
Side-scrolling platformers and top-down maps, including bird's-eye blob autotiling, carved paths, and 3/4 Zelda-style terrain.
Yes. Load a main tileset and an optional dedicated props sheet — Mosaic keeps them straight all the way through export.
Export a Tiled .tmx (works in Unity via SuperTiled2Unity and Godot's Tiled importer), a Phaser tilemap JSON, or use the included native Godot loader script. A raw tile-grid JSON and PNG are always available too.
No. Mosaic runs entirely in your browser — your tilesets never leave your machine.
Labeling, editing and previewing are always free. You spend credits on the outputs you ship — generating a map, saving or downloading PNG/JSON, and exporting to a game engine. Every account gets free monthly credits, and paid plans grant a larger monthly bundle. See the pricing page for the full breakdown.
Yes. Edit Map mode lets you repaint any cell and manage layers, and Place mode lets you stamp decorative props exactly where you want them.
