Current plan on implementing an autorouter? It would be nice if it could be both packaged with LibrePCB and have a separate server that could be run on the same network. For example, you could have a dialog to select local or remote autorouting. With remote, you would supply an ip and it would send your board to a server to run the calculations.
Currently there are no plans to add an autorouter (other features have much higher priority). But at least the push&shove router from KiCad is planned to be added, see Add interactive push and shove router from CERN/kicad/horizon.
