Rusty Object Notation

🎒 Token-Oriented Object Notation (TOON) – compact, human-readable serialization of JSON data for LLM prompts. TypeScript SDK, CLI, benchmarks.

Pure Rust HDF5 implementation

Self-hosted authentication & authorization system (IAM: OAuth2 & OpenID Connect provider with realms, RBAC & ABAC policies, MFA (TOTP, passkeys, email OTP), identity federation (OIDC, LDAP) and session management.

Python library for serializing any arbitrary object graph into JSON. It can take almost any Python object and turn the object into JSON. Additionally, it can reconstitute the object back into Python.

A fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML

Rust implementation of Binary Object Representation Serializer for Hashing

Library for (de-)serializing data of any complexity (supports JSON, and XML)

Semantic parser for API specifications

A feature-packed .NET MessagePack serialization library with great performance and simplicity. msgpack.io[C#]

A thrift and protobuf implementation in pure rust with high performance and extensibility.

A fast Rust JSON library based on SIMD.

High-performance Protocol Buffers for JavaScript and TypeScript. Conformant through Edition 2026, and unusually versatile. No protoc required.
