The better stack rn is buf + Connect RPC: https://connectrpc.com/ All the compatibility, you get JSON+HTTP & gRPC, one platform.

Software lives forever. You have to take the long view, not the "rn" view. In the long view, NFS's XDR or ASN.1 are just fine and could have been enough, if we didn't keep reinventing things.

It's mind-blowing to think XDR / ONC RPC V2 were products of the 1980s, and that sitting here nearly forty years later we are discussing the same problem space.

Probably the biggest challenge with something like XDR is it's very hard to maintain tooling around it long-term. Nobody wants to pay for forty years of continuous incremental improvement, maintenance, and modernization.

Long term this churn will hopefully slow down, it's inevitable as we collectively develop a solid set of "engineering principles" for the industry.

And yet somehow, we are willing to pay to reinvent the thing 25 times in 40 years.

It's a different company paying each time ;)

I'm actually super excited to see how https://www.sovereign.tech turns out long-term. Germany has a lot of issues with missing the boat on tech, but the sovereign tech fund is such a fantastic idea.

I'm using connectrpc, and I'm a happy customer. I can even easily generate an OpenAPI schema for the "JSON API" using https://github.com/sudorandom/protoc-gen-connect-openapi

ConnectRPC is very cool, thanks for sharing. I would like to add 2 other alternatives that I like:

- dRPC (by Storj): https://drpc.io (also compatible with gRPC)

- Twirp (by Twitch): https://github.com/twitchtv/twirp (no gRPC compatibility)

Buf seems really nice, but I'm not completely sure what's free and what's not with the Buf platform, so I'm hesitant to make it a dependency for my little open source side project ideas. I should read the docs a bit more.

Buf CLI itself is licensed under a permissive Apache 2.0 License [0]. Since Buf is a compiler, its output cannot be copyrighted (similar to proprietary or GPL licensed compilers). DISCLAIMER: I am not a lawyer.

Buf distinguishes a few types of plugins: the most important being local and remote. Local plugins are executables installed on your own machine, and Buf places no restrictions on use of those. Remote plugins are hosted on BSR (Buf Schema Registry) servers [1], which are rate limited. All remote plugins are also available as local plugins if you install them.

It's worth to mention that the only time I've personally hit the rate limits of remote plugins is when I misconfigured makefile dependencies to run buf on every change of my code, instead of every change of proto definitions. So, for most development purposes, even remote plugins should be fine.

Additionally, BSR also offers hosting of user proto schemas and plugins, and this is where pricing comes in [2].

Ok, that makes sense. Thanks!
