OpenSMO (oline srv) is still supported in OutFox LTS

FYI: it is still supported, devs haven’t removed the smo net code, so you can connect to a SMO-based server (if available)
@Jousway recently made a rewrite of it, which is available on Tiny-Foxes.

Also, original OpenSMO ( looks like abandonware and none of it’s forks is alive.

Indeed. The upcoming LTS 0.4.19 release should improve the experience for OpenSMO players.
