Foundry Virtual Tabletop (FVTT)
It's a non-game specific virtual tabletop with a dnd 5e module during development.
What features does it provide for D&D 5E? I've been looking into VTTs.
That is the dnd 5e module open source and the additional support modules can be found in the 2nd link.
As far as features for DND 5E it offers everything a full subscription to Roll20 offers, to my knowledge. It also has importers for Roll20 content you might want to transition. It is all legal though so Foundry itself does not provide non-SRD openGL content. If you pair it with DnDBeyond via the Beyond20 app then you have all licensed content and the dndbeyond character sheets which you can roll from directly.
I would list out unique features but honestly I can't think of any dnd specific features that are part of the agnostic base engine. If you had a question about something you hoped it had I could probably confirm or deny it supporting that.
@Jeshin Oh I want to, but I'd rather not derail your thread by asking too many generic questions about VTTs so I'll STFU. :)
