A truly stripped down binary-protocol can be faster and leaner than JSON, but for web-work JSON is highly preferred. Why? Javascript has zero tools for handling binary data and PHP's binary support is all but non-existent.<div>

<div>The ease of using JSON in Ruby + PHP + javascript + iOS + Android more than makes up for the wire overhead. And it's easier to read tcpdump/pcaps, use existing tools like curl and read native traces/dumps.</div>

I was thinking about the same,<br>
after some testing I went to use JSON it was smaller then BERT+base64 for my cases without it I had problems with transmissions.<br>
