Open source at the core
Every RPGJS game runs on the same open-source engine. Write your game in code for free, or open Studio and let AI and visual tools do the heavy lifting.
The open-source TypeScript engine behind every Studio game. Build your RPG or MMORPG in code and own every line.
Your whole game studio in the browser: generate, build, test and publish, powered by the same engine.
Studio projects export to the open-source engine, so you are never locked in.
How it works
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
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.
2Step 2 · Create your characters
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
Place a villager, write what they say, and hand out a quest. It feels like writing a story, and your players will live it.
★ New quest: The Hidden Path
Welcome, traveler! Bring me three apples from the market and I’ll show you the hidden path.
4Step 4 · Level up your game
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.
● Cutscene“So you finally came… The dragon has been waiting.”
> Add a dragon boss fight after this cutscene ✓ Connected to RPGJS Studio API ✓ Boss event added to “Throne Room”
5Step 5 · Play & share
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.

3 players onlineWhy RPGJS Studio
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.
Generate maps, characters, textures and music without leaving the editor. The other tools need plugins, extensions or nothing at all.
Map editor, events, dialogue and quests are already there. No template hunting, no plugin stack to assemble.
The MIT engine is yours, and every Studio project exports to RPGJS source you can host anywhere.

Simple pricing
No monthly subscription to build your game: unlock the complete Studio with a single payment and keep it forever.
Free
For your first worldsLifetime license
For creators who want it allEverything in Free, plus:
Need more AI credits? Optional subscriptions refill them every month.
Credits are spent each time the AI generates something for you. A complete map costs 50 credits. Characters, textures and other assets use credits too. Everything the AI creates stays editable.
Lets an AI agent such as Claude Code or Codex work directly in your Studio project: create maps, add events, generate assets and export your game. Optional, the editor works without it.
Plenty of room for your maps, sprites, music and project data, so you never have to clean up to keep creating.
No. The free plan lets you create maps, events and playtest in your browser, without a credit card. AI generation needs credits, which come with the license.
From a short description, the AI generates complete maps, and also characters with their animations, facesets, textures and music. Everything lands in your project as editable content: you can repaint, move and fix anything by hand.
A credit is what the AI spends when it generates something. A complete map costs 50 credits. The lifetime license includes 500 credits, which is about 10 maps.
Everything else keeps working: the editor, your projects, playtesting and export. If you need more credits, optional subscriptions refill them every month at https://rpgjs.studio/buy, with no need to buy another license.
A one-time payment unlocks 100 GB of cloud storage, 500 AI credits, access to your project data and the Studio API key, plus every future improvement. New paid features, like a much more elaborate MMORPG toolkit, are coming in the next weeks.
The API key gives programs access to almost all Studio features, including the map generator. Its main use is connecting an AI agent such as Claude Code or Codex, which can then create maps, edit events, generate assets and export your project for you. You do not need it to use Studio.
Give your agent the Studio skill from https://v5.rpgjs.dev/studio, along with your API key. The agent can then use the Studio API to automate the creation of your game.
Yes. Every project exports to RPGJS source code, either offline (your game includes its data) or online (it stays connected to Studio). The RPGJS engine is open source under the MIT license.
Yes. Commercial use of generated content is allowed, and you own what you create.
