LibreELEC builds and hosts a number of Kodi binary add-ons to extend functionality, e.g.
We also provide a range of program/service add-ons, including:
.net Core Runtime
JRE for BD-J menus
Raspberry Pi Tools
"Tools" add-ons bundle multiple binaries into a single add-on with a themed purpose to reduce repo maintenance. Look in the Kodi GUI and the info panel will tell you the list of binaries in each bundle.
