I’ve used https://ziahamza.github.io/webui-aria2/ in the past to manage aria2c with aria2c running on localhost (see https://github.com/ziahamza/webui-aria2/blob/master/README.m... for instructions) and the webui loaded directly from said address. That was a while ago and I don’t know if any browsers still allow access to localhost by default but at least some of them did last time I used that webui at least.
