Unity and WebGL is pretty common now days. You'll find a good chunk of the games at https://itch.io/games/html5 use exactly that.

Unity supports builds targeting WebGL and WASM.

Last time I stumbled on an "io game" built this way, the lack of WASM debugging tools made it very hard to hack at the game :(
