PROGRESS REPORT: Web Export in 4.3

Listen up :loud_sound:

The Web platform is getting some quality of life upgrades, snuck in right before the 4.3 feature freeze :cold_face::snowflake:

Read the Progress Report:


  • New single-threaded export option
  • Web Audio samples prototype
  • PWA COOP/COEP helper
  • Boot screen displayed while loading

Featuring Catburglar :cat::gem:

Help yourself to the cityโ€™s valuables in Catburglar, a stealth platformer inspired by Trilby: The Art of Theft. Play as Cynth, and use your wits and agility to steal through a series of highrise apartments, outwitting guards and security cameras as you make your way to your goal.


Amazing post and incredible work. I have a question: how does other engines, specially Unity, deal with multi threading on the web? Do they also rely on SharedArrayBuffers and had to disable it? What about COOP/COEP? Is their strategy totally different?

Unity WebGL:

Seems like exactly the same tradeoff: single threaded unless you enable COOP/COEP and fall into the problems of doing so.
