Godot 4.3 adds single-threaded web export
Godot 4.3, released on August 15, 2024, brings back single-threaded web exports as a major quality-of-life improvement.
Why it matters
Multi-threaded web exports require special HTTP headers (COOP/COEP) that many hosting platforms don't support or make difficult to configure. Single-threaded exports work everywhere:
- itch.io and other game portals
- GitHub Pages and static hosts
- macOS and iOS Safari (which had issues with multi-threaded builds)
What changed
- Single-threaded export is now available and enabled by default
- Multi-threaded export still available when needed
- Reduced hosting friction for indie developers
