looking glass software

[Bogdan <shoshon () shoshon ro>]

hello

what software do you use for looking glass. for cisco ios and ios-xr?
i use the old cougar/version6.net for ios, but ios-xr is not supported.
i came across https://github.com/tmshlvck/ulg/ but did't installed yet.
are there any other interesting lg's out there?
thanks.
