online version is https://svaaps.github.io/eaglercrafthtml/ (online version saves individual worlds too and works just as normal as the local version but you don't have to download anything) if you wanna play eaglercraft locally like a weirdo, its in releases
you can also clone this to make your own copy of the web version of eaglercraft
none of this is made by me, all credit goes to lax1dude.this is the original version link by lax1dude - https://github.com/lax1dude/eaglercraft. i am not at all related to this, i just wanted to make it easier to get it on the web without downloading.
