Wireproxy can do similar stuff: https://github.com/octeep/wireproxy

Thanks for the link! IIUIC, wireproxy is not similar, but complementary: you can run wiretap on the server-side and wireproxy on the client and have a complete user-space solution.

Much better name. Initially I thought Wiretap was a MITM proxy for Wireguard.
