I'm yet to see enough services expose a gRPC endpoint, at least other than Google. That'll keep the perception of adoption s/low. I'm writing this as I take a break from working on a polyglot project made up of Kotlin, Rust, Node, where we use gRPC and gRPC-web. We're slowly stealing endpoints from the other services/languages to Rust. Without focusing on the war of languages, the codegen benefits of protobufs have made what used to be a lot of JSON serde much easier.

Can you point to a single public Google-run gRPC service? I was under the impression that all connections into Google are proxied by GFE (Google Front-End) servers to internal servers running the Stubby RPC server code. GFE is definitely not running gRPC server code. I don't believe a gRPC endpoint could pass Google's own Production Readiness Review process.

  I've seen Google endpoints available over gRPC over the last few years. Many, if not most, of the Cloud endpoints are directly documented as being available over gRPC[0]. For others, like Google Ads, a peak at the client libraries show it's using gRPC[1] as well.

    Yes, this. A lot (based on my last interaction 2 yrs ago) of Google's SDKs are convenience methods that hide gRPC behind. If you use a language that doesn't have an SDK, you can mostly connect directly to their rpc endpoints.

  The googleapis [1] repo has the publicly accessible gRPC definitions, which you can access directly. I've done this before, though it was a bit tedious as I had to learn how to manually pass Google credentials (documentation wasn't good enough).
