I want to host a fediverse instance but I need it to be light (limited system resources). Mastodon seems to be kinda heavy. GotoSocial is supposedly very light? (but limited on functionality?) is Pixelfed much heavier? Bonfire is built on elixir so should also be light? Akkoma? Pleroma?
Also, I need it to be engaging to people migrating mostly from IG, so I do need some bells/whistles I guess
thanks!
EDIT: The instance is supposed to be hosting a community of 100-200 people. Maybe even more in the future (in which case we would probably migrate to another server)
Having a “facebook pages” / mini website / pixelfed portfolio is very functional for the people I plan to invite.


For a single user instance (or friends - family) pretty much anything will do.
Consider also ease of administration, upgrade smoothness. It vary quite a lot depending on the stack and maturity of instances flavors.
looking for something for a community of 100-200 I guess
With 200 accounts and 5 to 10% active users that is 10 to 20 concurrent connections on peak hours. Probably more like <10.
In that range you still should prefer lightweight instances with best admin and moderation tools.
System load and storage will be more affected by the federation itself than you user activity.
