To get an overview of the area of binary interchange formats that are language agnostic, the author of Cap'n Proto does a good job in this:

"Protocol Buffers" has been the go-to for a long time but there are more options now.

For uses where serialization/deserialization CPU time is a concern, it seems to really a question of Cap'n Proto versus flatbuffers ( https://google.github.io/flatbuffers/ ).

For some reason, the banner (infinitely faster?), name, and introductory FAQ-style responses made me think the whole thing is a joke - similar to Vanilla JS [1].

Anyways, it seems like a cool project, so I'll be sure to follow its development closely.

I had the exact same reaction. I really had to read for a long time (including code) before deciding it was real. "infinitely faster" confused me too.

I originally released it on April 1st, 2013, with the announcement post:

So, uh… I have a confession to make.

I may have rewritten Protocol Buffers.

Again.

Although this is listed on the introduction page, the author is also the same person that co-founded Sandstorm.io[1].

Interfaces! Inheritance! Looks promising. Protocol buffers are nice for their compact encoding and multi-language generator support but as a schema language they are really cumbersome. Composition is pretty much all you get, there are no longer required fields, you can't even use enums as a key type in a map. I'm sure their use cases are not necessarily the same as mine but sometimes I miss just using plain old XML.
