I recommend Capnproto. Parsing time is zero, you can pretend you're a Microsoft programmer in the early 90s and just use the in-RAM struct as your wire format.

Maybe it doesn't make sense for in-browser JS applications (though WASM is a different story) but for IPC and RPC in the general case, all parsing and unparsing does is generate waste heat. ALWAYS favor a binary format unless you have a really good reason otherwise.

Capnproto is designed by Kenton, a former Google engineer who did a lot of work with protobufs at Google. I see Capnproto as the spiritual successor of protobuf, fixing many issues in protobufs. Also, Capnproto is quite extensively used in some Cloudflare products.
