At the moment I think whitequark's is probably the simplest,  easiest,  and most well tested.  Ocaml-protobuf will be implemented in terms of his once I get sufficient time and motivation.  Ocaml-protobuf provides a monadic interface which I prefer and whitequark's does a lot of the heavy lifting for you.

Hello,

Is anyone out there using OCaml with Protobufs? If so, what library/tools are you using, and how do you like the setup? Also, are you using Protobufs in a production setting?

I found online but have not used any of the below myself:

1) piqi - http://piqi.org/

2) obitz - https://github.com/orbitz/ocaml-protobuf

3) whitequark's protobufs - https://github.com/orbitz/ocaml-protobuf

Curious to hear your experiences. Thank you.

Trevor
