Here's a Unity Package that lets you publish webGL builds of your game directly from Unity.

I put it together so a friend and I could easily share dev builds during game jams so its pretty minimal, not exactly a full featured butler UI for unity. But maybe someone else will find it useful and add more 😉.

That's really neat, thanks for posting.

hey anybody want to join a jam
