Probably because it was a closed source project until a few days ago.

There is no magic here. From the description:

"Zapcc uses in-memory compilation cache in client-server architecture, remembering all compilation information between runs. ‘zapcc’ is the client while ‘zapccs’ is the server. Each zapcc run will reuse an existing server, or if none available will start a new one. »

IIRC, the where some discussion in the past about writing a clang caching server, but I don’t think anybody worked on it.
