How it works

From idea to playable game
in 5 steps.

Everything happens in RPGJS Studio, right in your browser. No install, no code required, and you can export the source anytime.

1Step 1 · Generate your map

Describe a place. Get a real map.

Type one sentence and Studio builds the terrain, paths, buildings and forests in the style you ask for, as editable tiles, not a flat image.

Any visual style
Real tiles & layers
Repaint anything

2Step 2 · Create your characters

Missing a hero? Generate it.

Describe a character and get it ready to walk, in the pixel-art style that fits your world. Faces, animations and terrains work the same way.

3Step 3 · Tell your story

Make your world talk.

Place a villager, write what they say, and hand out a quest. It feels like writing a story, and your players will live it.

Welcome, traveler! Bring me three apples from the market and I’ll show you the hidden path.

4Step 4 · Level up your game

Add cutscenes, combat and your own AI agent.

Stage cinematic cutscenes, build real-time action-RPG fights with skills on the hotbar, and, if you code, plug your AI agent like Claude Code or Codex into Studio through the API.

✓ Boss event added to “Throne Room”

5Step 5 · Play & share

Press play. Share a link.

Your game already has its interface: title screen, main menu, character select, HUD, hotbar and shop. Play it in the browser, send the link to friends, open it as an online MMORPG, or export the source.

Why RPGJS Studio

Everything an RPG needs.
Nothing to set up.

General-purpose engines make you assemble plugins and settings before your first map. Studio ships the whole RPG toolkit, ready the moment you sign in.

AI built in

Generate maps, characters, textures and music without leaving the editor. The other tools need plugins, extensions or nothing at all.

RPG-ready on day one

Map editor, events, dialogue and quests are already there. No template hunting, no plugin stack to assemble.

Open source, never locked in

The MIT engine is yours, and every Studio project exports to RPGJS source you can host anywhere.
