Note on third‑party tools

              

We aim to provide accurate and helpful details about third‑party tools, but we can’t guarantee that this information is always complete or up to date.

[MessagePack](https://msgpack.org/) is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it's faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves. See MessagePack's website for encoding information.
