I actually evaluated and used jsmn and almost mentioned it in my comment. It was really quite cool, but I believe I couldn’t use it due to the lack of UTF-8 validation. Because UTF-8 validation is in the state machine for libjson, I can actually ignore incomplete UTF-8 escape sequences in incomplete JSON strings when streaming.
