Continuwuity. I'm using it. And contrary to other projects, it's a community effort. So I have my hopes up it'll last and not depend on any singular person.

And I wouldn't recommend Conduit or Conduwuit. Conduit development is very slow, that's why we got the forks in the first place. And Conduwuit is discontinued, so it wouldn't be wise choice at all. So you're left with 2 choices, Tuwunel and Continuwuity. One is a one-man show and they're calling it the "official" successor. The other one is a community project... They both work fine.
