A harness built for game dev
WASD Engine bundles everything you need to build high-polish games in a single agent harness, so your agents can build from start to finish. Describe the game you want, and the agent plans it, writes the code, makes the models, textures, music, and sound effects, then plays the game to check its own work.
Godot is built into the Desktop app, and so are SuperCollider and GIMP on macOS. Blender sets itself up the first time the agent uses it, or uses the Blender you already have, and elsewhere the GIMP tools use your GIMP 3. The Poly Haven tools need nothing installed and download only the assets the agent picks.
Agents fill every game dev role
WASD Engine orchestrates agents to create art, music, and game logic, so your vision comes to life faster.
Built from plugins. Shaped by you.
Every capability in WASD Engine is a plugin. Use it as a complete workbench, or reshape it one piece at a time.
Works with any agent
Connect your existing subscription to WASD Engine for free using MCP. WASD Engine runs an MCP server on your computer that gives Claude Code, Codex, or any other agent the same game tools, and the games it builds play in the WASD Engine window. Bring the agent you already pay for, whether it runs on ChatGPT, Claude, Gemini, Grok, MiniMax, Kimi, or GLM.
To connect one, sign in to WASD Engine: the introduction that follows ends with Set up with another agent, which Settings → Other agents keeps for later. Paste the prompt it gives you into your agent.

Under the hood
- A real game engine in the loop. The Desktop app ships a patched LibGodot runtime. The agent runs each Session's game as its own process, gets its screenshots, logs, and errors back, sends it input, and streams it to the Game tab, where you can play it too.
- Creative tools without the windows. Blender, GIMP, and SuperCollider run headless behind MCP servers. The agent looks at its work through rendered previews, snapshots, and audio analysis with waveform and spectrogram images, and exports glTF models, textures, sprite sheets, and audio files into your project.
- Free assets on tap. The
polyhaven_* tools search Poly Haven's CC0 library by description in any language, show an asset's formats, sizes, and preview, and download one format and resolution into your project, with every file's checksum verified and nothing overwritten that you edited.
- Game projects with Git built in. Each game project is a folder under
Documents/WASD Engine with its own Git repository. Turn on Change requests & worktrees, and parallel Sessions each work on their own branch in a Git worktree, so they never overwrite each other.
- Game know-how out of the box. New Sessions use the Game developer preset with skills for Godot 4 (
godot-project) and design planning (game-design-doc). A skill directory with the same name under .agents/skills/ or .dsh/skills/ in your project replaces the bundled copy, so a team can pin its own engine conventions.
- Every piece is a plugin. WASD Engine is built on the Cordis plugin architecture: every tool, panel, and provider is a plugin row in a profile, and the Plugins page switches the game tools on and off.
- Private by default. Model requests carry no copy of your Session log unless you turn the Session log option on in Settings, and product analytics and telemetry exports are off. Sessions, settings, and credentials stay in
~/.wasdengine.
- Desktop, browser, or terminal. Use the Desktop app, the Web UI (
dsh web), or the dsh command line, including dsh acp for editors and dsh sdk for SDK clients.
Run from source
Install Node.js 24.9 or later and pnpm 11.28.5. Node.js 25 and later ship without Corepack, so install pnpm with npm install -g [email protected]. Then run:
git clone https://github.com/WASDEngine/WASD-Engine.git
cd WASDEngine
pnpm install
pnpm run build
pnpm dsh web
pnpm dsh web serves the Web UI at http://127.0.0.1:3080 and opens it in the default browser; pass --no-open to skip the browser. pnpm run dev:desktop builds and starts the Desktop app from the same checkout. pnpm run package:desktop:mac:arm64:unsigned builds an unsigned WASD Engine.app and disk image for Apple silicon Macs; add --dir to stop at the app.
Data lives in ~/.wasdengine unless DSH_HOME names another directory.
To keep your Sessions from another harness install that keeps its data in ~/.dsh, copy its sessions and attachments directories into ~/.wasdengine, and storages too if you want its workspace list and scheduled tasks. Do not copy its profiles directory, cordis.patch.yml, settings.yaml, or .credentials.yaml, and do not set DSH_HOME to ~/.dsh: the configuration files replace the WASD Engine service settings with the other install's, .credentials.yaml holds that install's keys and sign-in, and in a shared home each product deletes the other's sign-in at startup.
