It is nice and small server that do the basic well. I once use it on my poor $5 vps while being stuffed together with several of my PHP/MySQL apps. It has small footprint, several of my friends still use it on half-gigs ram vps.
But its lack of features sucks tho, there are no working filters, no disable re-toot per users setting (like on akkoma), and also there are no relay support so my timeline looks bare.
I migrate from GtS for now, but if above features are implemented in near future, may be I’ll migrate back to GtS.
