You can change your instance in Jerboa (and in all the Lemmy apps) fairly easily. I recommend retrying it, because it’s one of the best Lemmy apps available atm.

and yes, sh.itjust.works does indeed work in Jerboa!

If you know the basics of AWS/Azure/Cloudhosting (spin up VM, create users, login via ssh, register URL, etc.): really low (1-3) with the ansible recipe. With docker not much higher if you know the basics about docker that is.

If cloudhosting is not your forte, but are reasonably skilled in basic linux navigation, configuration, and upkeep use a Hoster that is doing a lot for you like DigitalOcean and read their tutorials. Since you still don’t need to configure a lot the challenge rises to a 4-5 maybe.

If you have never heard of hosting nor Linux it still isn’t the most difficult project to start learning to do these things. Setting up rises to a 6 or something. But keeping a Linux server running over an extended period of time is much harder than setting one up. Maintenance is difficult compared to a MacBook or something, so be prepared to read up on backup and restore docker containers and volumes and how to keep your instance reasonably updated without breaking your server. This would still not rise the difficulty above a 7.

Small disclaimer: In the past I have used alts and burners on Reddit all the time. I have the best intentions to keep my instance up to date and running smoothly, but if something catastrophic would happen, due to me meddling with stuff, I’d shut it down and start from scratch. I’m not clinging for my comments I wrote drunk at 03:00 AM.
