Ask HN: Possible to make a game engine in the browser?

Unity[0] and Unreal[1] both have some degree of support for targeting modern web browsers as platforms.

Not only is this possible, there's actually a bunch!

Unity has a WebGL player, but I guess Unity is dead now.

Other WebGL projects are the Quake 1 and Quake 3 Arena games ported to the web: https://www.netquake.io/ https://openarena.live/

PlayCanvas is a commercial offering: https://playcanvas.com/explore

There's also a bunch of open-source Javascript game engines: https://github.com/collections/javascript-game-engines

Of those, BabylonJS seems pretty powerful for 3D: https://www.babylonjs.com/games/

Or PixiJS for 2D: https://pixijs.com/

Lastly, there's also my personal preference... game streaming via GeForce Now (https://www.nvidia.com/en-us/geforce-now/) or Luna (https://www.amazon.com/luna/landing-page) or Boosteroid (https://boosteroid.com/). They're like Stadia, but actually alive, and GFN in particular works really, really well. Way better than trying to render graphics locally on my Mac (the RTX 4080 is way more powerful than even the M2 Ultra, and cloud streaming means no heat or noise or battery consumption locally). I hope that, not clientside WebGL/JS, becomes the future of web gaming.

Godot has a web editor [1] in case you don't know yet.

PlayCanvas is a game engine that runs on browsers, but I’m not certain what it’s future will be, it was bought by SnapChat, but SnapChat has shut down running games in app.

Creating a browser-based game engine with file system access and WebGPU support is promising, but it does come with limitations. Browser-based engines may face performance bottlenecks compared to native desktop engines due to factors like limited hardware access and reliance on web technologies. They might also have restrictions on file system access for security reasons.

However, the advantage lies in accessibility and ease of distribution. For complex, resource-intensive games, native engines like Unity or Unreal may still offer superior performance and capabilities, but browser-based engines can reach a broader audience with simpler games or interactive web experiences.
