RapidJSON is a C++ header-only JSON parser and generator. It's fast, easy to use, memory-efficient, and portable. RapidJSON can be used to parse and generate JSON documents in a variety of applications, including web servers, databases, and embedded systems. RapidJSON supports both JSON and CBOR data formats, and it can be used to parse and generate JSON and CBOR documents in a variety of programming languages, including C++, Java, Python, and JavaScript. RapidJSON is available under the MIT license, and it can be downloaded from the project's website.

RapidJSON is a very fast JSON parser and generator. It can parse JSON documents at a speed of up to 100MB/s, and it can generate JSON documents at a speed of up to 50MB/s. RapidJSON is also very easy to use. It has a simple and straightforward API, and it can be used to parse and generate JSON documents with just a few lines of code. RapidJSON is also very memory-efficient. It uses a memory-mapped file to store JSON documents, and it only loads the parts of the document that are needed. This makes RapidJSON very efficient for parsing and generating large JSON documents.


RapidJSON: RapidJSON is a JSON parser and generator for C++. It was inspired by RapidXml. RapidJSON is small but complete. It supports both SAX and DOM style API. The SAX parser is only a half thousand lines of code. RapidJSON is fast. Its performance can be comparable to strlen(). It also optionally supports SSE2/SSE4.2 for acceleration. RapidJSON is self-contained and header-only. It does not depend on external libraries such as BOOST. It even does not depend on STL. RapidJSON is memory-friendly. Each JSON value occupies exactly 16 bytes for most 32/64-bit machines (excluding text string). By default it uses a fast memory allocator, and the parser allocates memory compactly during parsing. RapidJSON is Unicode-friendly. It supports UTF-8, UTF-16, UTF-32 (LE & BE), and their detection, validation and transcoding internally. For example, you can read a UTF-8 file and let RapidJSON transcode the JSON strings into UTF-16 in the DOM. It also supports surrogates and "\u0000" (null character).
