So I've been running my own #Snac instance for the past week and I have to say that I'm actually loving it. It hardly takes up any resources and the inbuilt web interface is easily configurable with nothing more than #CSS .
There are some things that folk used to running #Mastodon might not like. For example it does not show any follower or following numbers to any instances. So people using Mastodon will see 0 followers and 0 following even though those Snac uses may have 100's of followers .
You do get a people tab on the snac interface that is just a list divided into people following you and people you follow but no numbers. This is an intentional design feature by the author @grunfink@comam.es who stated.

I haven't implemented a simple count of following / followers on purpose; I consider all metrics in network media inherently toxic, because it's a way of comparing the relative success of people. This is also why, as seen from other Fediverse implementations, snac accounts always report 0 / 0 connections.

Also not all features work with android / iOS apps but most of the essentials do. I occasionally use #Tusky when I'm not just using the web interface for Snac which I just find easier. I think I will be staying with this fantastic lightweight piece of software and look forward to see what new features get added in the future. A wish would be to have a way of importing followers from Mastodon to Snac, which I think the dev is working on at the moment. Oh and I nearly forgot to say that you can import the CSV file of people that you are following through the command line and it's fairly simple to do too. I'd 100% recommended giving Snac a try if you're looking for a no nonsene lightweight #Fediverse instance.
