Features

Everything you need to
build levels fast.

Mosaic does the tedious parts — edge detection, adjacency, fill, spacing — so you stay focused on how your level looks.

🏷️

Visual labeling

Click and drag to tag tiles by category. Shift-drag to capture whole blocks like skies, silhouettes & big props.

Smart generation

The generator infers caps, corners, edges and fill automatically. You never touch an adjacency rule.

🌲

Prop placement

Auto-scatter decorative props on valid ground only — or hand-place them with a pixel-perfect Place mode.

🗺️

Platformer & top-down

Side-scroller, bird's-eye, and 3/4 Zelda-style terrain — including blob autotiling and carved paths.

🎛️

Edit & refine

Repaint any cell, manage layers, and tweak the result until it's exactly right. Visual correctness first.

🎮

One-click engine export

Send finished levels straight to Godot, Unity, Phaser, or Tiled — tilesets, layers and GIDs included.

Spend your time
creating, not configuring.

Tools like Tiled and LDtk ask you to set up corners, caps, transitions and adjacency rules before you can build. Mosaic handles that logic for you — you just say what a tile is and shape the result. Dive into the deeper tile mechanics whenever you're curious; you'll just never be blocked waiting to.

Plays nice with your stack

Export to any engine

Mosaic outputs a clean tile grid plus engine-native files — tilesets, layers and tile IDs already wired up.
