Prepare your first build
- Export one UTF-8 HTML or HTM file, no larger than 2,500,000 bytes.
- Keep scripts, styles and artwork self-contained. Future isolated delivery blocks external network requests, external scripts, forms and embedded frames. Use inline code and data assets.
- Use artwork, music, names and code you have the rights to distribute. Remove credentials, analytics trackers and personal information.
- Test both keyboard and touch controls. Include readable instructions, accessible contrast and a way to restart.
Submit privately
- Sign in using an email link opened on the same device where you use the workspace.
- Save a draft with a title and short description.
- Select that draft and upload the HTML build.
- Request review and check its status in your workspace. An authorized reviewer can inspect the submitted source.
After approval, private release preparation and final publication are separate steps. Those launch controls remain gated during testing. No game becomes public merely because it is approved.
Preview limits
Up to 50 drafts and 10 upload slots per account. Incomplete uploads count toward the limit. Staging currently has a shared limit of 100 upload slots. ZIP packages, native Unreal/Unity builds and GPU streaming are not supported.
SDK and monetization
The legacy SDK, CLI and instant-publish APIs are experimental local prototypes, not supported public services. Do not install packages or send game source to old domain examples. No SDK integration is required for this private submission workflow. Multiplayer, wallet integration, commercial pricing and creator revenue shares are not finalized.
