Unity — WebGL Build and Deployment Tips

To test WebGL builds for free on small projects, upload your source code to GitHub and configure GitHub Pages settings.

Currently, Unity strongly recommends compressing in Gzip format during build. Since the browser handles decompression, you need to enable Decompression Fallback in Project Settings > Publishing Settings.

For self-hosting cases, if the server itself doesn't have Gzip decompression configured, issues may arise. As a quick alternative, you can build without compression.
