Open-source engine + cloud studio

Build your RPG with code, AI, or both

RPGJS Studio is a cloud workspace for developers and creators building 2D RPGs. Design maps, manage game data, generate assets, export your project, and connect coding agents directly to your RPG workflow.

The RPGJS engine stays free and open source. A lifetime Studio license unlocks the production workflow around it.

Start with an AI coding agent

FAQ

Is the RPGJS engine still free?

Yes. The RPGJS engine remains open source under the MIT license. You can build with code for free, with or without Studio.

What does the Studio license unlock?

The lifetime license unlocks the cloud workspace: unlimited maps, game database tools, events, asset generation, RPGJS-compatible exports, 10 GB of storage, and 500 AI credits included at purchase.

Do I have to use RPGJS as the final engine?

No. Studio can export a project compatible with RPGJS, with offline or online data. You own the final game and can continue outside the editor whenever you want.

How do coding agents work with Studio?

Install the RPGJS Studio skill, create an API key, and agents like Codex, Claude Code, or OpenCode can create maps, edit database entries, configure events, export the project, and help with custom code.

Open-source core

Start with the free engine. Add Studio when you want the cloud workflow.

RPGJS gives developers a free and open-source foundation. Studio adds editors, generation tools, project data, playtesting, AI-assisted workflows, and exports that let the creator keep ownership of the final game.
