DSH Game Studio is an open-source plugin for DeepSeek Harness (dsh), DeepSeek's agent harness, which is in developer preview. You ask for a small game in a sentence, and the agent adapts one of two starter templates to fit it: a 2D top-down game or a 3D voxel version built with three.js. The game plays in a sandboxed panel beside the chat, rebuilds after each edit, and each build that changes it is kept as a version you can restore.
According to the project's README, the agent can also test its own work: it runs the newest build in headless Chrome or Edge and reports the score, frame rate, script errors and screenshots. Characters start as code-drawn shapes; for real art, the plugin makes numbered image candidates through the OpenAI image API or the Codex CLI, after you approve an estimated cost. Finished games export as a single offline HTML file.
The plugin is free under the MIT license; image generation is billed by OpenAI or comes out of your Codex plan. The README lists DeepSeek Harness 0.2.1 or later and Node.js 24.11 or later, and says it was tested with dsh 0.2.1-rc.5.
The README reports the developer's own runs with DeepSeek-V4.1-Flash on November 4 and 5, 2026: all 10 collect-and-dodge requests were playable on the first try (median about 14 minutes), and all 10 requests in other genres ended up playable (median about 26 minutes). AIGamer has not tested it. The current release, 0.1.0-rc.3, is a release candidate.
Limitation: Games are built from two templates (a 2D top-down game and a 3D voxel version of the same loop); in the developer's own runs, genres outside collect-and-dodge took about twice as long, and the README notes the sample is small
FAQ
Is DSH Game Studio free?
Yes. The plugin is open source under the MIT license. Optional AI art is billed to your own OpenAI API key or uses your Codex plan, and the README says you approve an estimated cost before any image is generated.
What do I need to run DSH Game Studio?
According to the README: DeepSeek Harness 0.2.1 or later (web or desktop; the developer tested with 0.2.1-rc.5), Node.js 24.11 or later, and Chrome or Edge on the same computer for playtests. It installs from npm with `dsh plugin --profile web add @zseven-w/dsh-game-studio@latest`.
Can I take my game out of DSH Game Studio?
Yes. The export tool writes one self-contained HTML file that needs no network connection; the README says it can be opened in any browser or hosted on a static site.
What kinds of games can DSH Game Studio make?
Every game starts from a 2D top-down template or a 3D voxel template. The README lists test runs in other genres too, including match-3, tower defense, platformer and rhythm games; all were playable but took longer than collect-and-dodge games.
