Isometric Builder

Build isometric pixel-art scenes in your browser with every piece of all seven Gridwright isometric packs inside: stack blocks into hills and cliffs, paint paths and rivers, put up houses, rooms and crypts, and fill them with furniture, props, characters and monsters. Then save it as a picture, an animated GIF, or a scene for Godot or Tiled.

Try it first: the free demo is on this page (it builds with the pieces of the packs' free samples and saves PNGs with a small mark).

Licence in one line: use what you build in your own games and projects, commercial too; do not resell or share the tool or the sprites as files.

What you get

• The builder: one HTML file that runs offline in your browser (tested in Edge and Chrome on Windows; made for Firefox and Safari too). No install, no account; nothing leaves your computer. A mouse is best.
• 440 pieces from 7 packs in a searchable library: terrain blocks and half blocks, ramps and stairs, water, lava, acid and ice, waterfalls, paths, floors, mist, fences, hedges and walls, doors, props, trees, buildings, furniture in 4 directions, graves and tombstones, dungeon and mine props, and 40 heroes, villagers and monsters in 8 directions, animated.
• All seven packs' own files as separate downloads on this page: Isometric Tiles, Isometric Interiors, Isometric Graveyard & Crypt, Isometric Dungeon & Caves, Isometric Characters, Isometric Monsters, Isometric Character Creator (single PNGs at 1x, 2x and 3x, sheets with JSON, palettes and their licences). Bought one by one they are $34.93.
• 9 starter scenes: the village, island, dungeons, house, shop, graveyard, crypt and cave from our store pages, ready to open and change.
• Add more, freely: any compatible pack as its .zip (every new Gridwright isometric pack drops straight in, and the README shows the format for your own), and your own PNGs one by one. The Packs list shows what is inside.

Build it like a 3D scene

• Real height: stack blocks up to 12 high, paint their tops or level an area to a height (the dirt under grass, snow and sand is filled in for you). Everything is drawn in the right order, so a tower stands in front of the hill behind it and a tree hides the house behind it.
• Pieces that join by themselves: paths by their corners, fences, hedges, cemetery walls and mine rails with their neighbours and gates, water with foam on its banks, walls with their corners and wall ends. Full or low (cut-away) walls, with doors, windows, bars and ore.
• Turn furniture in 4 directions and characters in 8 with one key. Rugs lie flat under furniture; shadows fall on the ground.
• Animated and by night: water, lava, fire, mist and characters move; at night lamps, windows, candles and crystals glow and the rest goes dark.
• Undo and redo, rectangle fill, pick (eyedropper), search, maps up to 64 x 64 cells; Save and Open your maps, and your last map comes back by itself.

Take it to your engine

• PNG at 1x to 8x, transparent or on a colour, by day or night, for mock-ups, store pages and backgrounds.
• Animated GIF of the whole scene.
• Godot 4: a folder with the sprites and a ready .tscn scene (tested in Godot 4.7).
• Tiled: a .tmx map with a .tsx tileset: every sprite as a tile object in drawing order.
• JSON: every sprite in drawing order with its pixel position, plus the editable map (stacks, paths, walls, objects), for any engine.

How it was made

The builder's code was written with an AI coding assistant and tested by us with automated checks (stacking, joins, walls, turning, undo, every starter scene, every export, the Godot scene loaded in Godot 4.7). The pixel art was drawn by code an AI wrote (no image generator). That is why the page is tagged AI Assisted (Graphics and Code).

Every Gridwright isometric pack is also in the Isometric Bundle, and every pack we make is in the $20 Megabundle. See our packs in a real game: Gridwright Survivors (free demo).
