What is OpenGame?
OpenGame is an AI game generator and Studio workspace for creating playable browser games. Describe your idea in a prompt, choose 2D or 3D output, and the Agent builds a project you can preview, refine, and publish — all in the browser, with no desktop game editor required.
Key Features
- Prompt-to-game generation — Turn a written brief into a playable 2D HTML5 prototype or a multi-file 3D browser game.
- 2D and 3D output modes — Pick a single-file HTML5 game or a downloadable 3D ZIP bundle depending on your goal.
- Visible build activity — Follow the project from request to ready artifact so you always know what the Agent is doing.
- Playable preview and iteration — Test controls and mechanics in Studio, then refine the game through continued prompting.
- Saved project files and export — Download playable HTML or a complete 3D project bundle when the build is ready.
- Showcase and remixable examples — Study featured browser games and flagship builds, then carry their prompts and design direction into your own project.
How It Works
- Choose 2D or 3D.
- Describe the game clearly, including controls and goal.
- Preview the generated result and fix issues through iteration.
- Download your project files.
Credits and Pricing
Every generation uses Studio Credits: 5 credits for one 2D game and 10 credits for one 3D game. Plans include Starter at $15/month (80 credits), Creator at $29/month (180 credits), and Studio at $49/month (360 credits), with monthly or annual billing. Saved projects stay available for preview and download without additional credits.
Who It's For
OpenGame suits indie developers, game designers, prototypers, and creators who want to test game ideas quickly in the browser. Public example games can be played for free without an account; generating your own project requires sign-in and Studio Credits.
