​
Bundle Format

All game submissions to Greenhouse Games must be uploaded as a single .zip archive. This page covers the format requirements and constraints your bundle must meet.

​
Archive Format

Your game must be packaged as a single .zip file. No other archive formats (.tar, .rar, .7z, etc.) are accepted.

​
Size Limits

Maximum File Size

1 GB (1,073,741,824 bytes)
Your .zip archive must not exceed 1 GB in total size. If your bundle exceeds this limit, consider:
  • Compressing image assets (use WebP where possible)
  • Reducing audio quality or using more efficient codecs (.ogg or .m4a instead of .wav)
  • Removing unused assets from your build

​
File Count Limit

Maximum Extracted Files

10,000 files
When extracted, your .zip archive must contain no more than 10,000 files in total. This includes all files across all subdirectories.
If your game uses a build tool (Webpack, Vite, Rollup, etc.), ensure your production build doesn’t include source maps or development artifacts that inflate file count.

Summary

Next Steps

Once your bundle meets these format requirements, ensure your folder structure is correct and index.html is in the right location.
