I was about to use gRPC, but forget that non-browser-supporting non-human-readable dumpster fire.

Also it looks significantly less complicated than open api/swagger. for starters, openapi/swagger has 2 fkin names. lol.

You can use JSON as the serialization format for gRPC, so that's not really a great reason not to use it.

I would argue that GraphQL is a bigger competitor and much friendlier to web apps.
