body: <p>Both are serialization libraries and are developed by Google developers. Is there any big difference between them? Is it a lot of work to convert code using <a href="https://developers.google.com/protocol-buffers/" rel="noreferrer">Protocol Buffers</a> to use <a href="https://google.github.io/flatbuffers/" rel="noreferrer">FlatBuffers</a>?</p>
