As far as I’m aware, the only self hosted player character builder is the charactermancer in plutonium, the patreon-accessible Foundry VTT plugin made by the 5e.tools folks — but man. My kingdom for a dndbeyond alternative, something self hosted that can take open 5th edition content and allow my players to build and save their character sheets. I don’t suppose I’m just missing something already out there, or are there any projects I should be following?

Not self hosted but I believe it is open source. Their discord has content packs that cover all officially released content.
Actually… this looks like exactly what I’m looking for! It looks like you can pretty easily host it yourself. I’ll need to dig into this, thanks for letting me know!
