RethinkDB allows developers to build scalable realtime apps in a fraction of the time with less effort.
JSON for Humans.
JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. (Keep using JSON or other file formats for that. 🙂)

JSON Structure is a data structure definition language that enforces strict typing, modularity, and determinism.
JSON Structure is a schema language that can describe data types and structures whose definitions map cleanly to programming language types and database constructs as well as to the popular JSON data encoding. The type model reflects the needs of modern applications and allows for rich annotations with semantic information that can be evaluated and understood by developers and by large language models (LLMs).

JSON formatter that produces highly readable but fairly compact output.
FracturedJson is a family of utilities that format JSON data in a way that's easy for humans to read, but fairly compact. Arrays and objects are written on single lines, as long as they're neither too long nor too complex. When several such lines are similar in structure, they're written with fields aligned like a table. Long arrays are written with multiple items per line across multiple lines.

BSON, short for Binary JSON, is a binary-encoded serialization of JSON-like documents. Like JSON, BSON supports the embedding of documents and arrays within other documents and arrays. BSON also contains extensions that allow representation of data types that are not part of the JSON spec. For example, BSON has a Date type and a BinData type.
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

A super fast CLI tool to decode and encode JWTs built in Rust.
jwt-cli is a command line tool to help you work with JSON Web Tokens (JWTs). Like most JWT command line tools out there, you can decode almost any JWT header and claims body. Unlike any that I've found, however, jwt-cli allows you to encode a new JWT with nearly any piece of data you can think of. Custom header values (some), custom claim bodies (as long as it's JSON, it's game), and using any secret you need.
JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.
