We do! See https://benchmark.sourcemeta.com for a live benchmark and https://arxiv.org/abs/2211.12799 for a more detailed academic benchmark.

The TLDR is that is that if you use JSON BinPack on schema-less mode, its still more space-efficient than MessagePack but not by a huge margin (depends on the type of data of course). But if you start passing a JSON Schema along with your data, the results become way smaller.

Please reach out to jv@jviotti.com. I would love to discuss your use case more.
