## What it is
OdinSerializer is a fast, robust, and extensible .NET serialization library built for Unity, open-sourced from the serializer used by Odin Inspector. It supports binary and JSON formats, Unity structs, and compares favorably in performance and allocation against alternatives like JSON.NET and protobuf-net.

## Use cases
- serialize game save data in unity
- fast binary serializer for .NET
- serialize unity structs and objects
- replace binary formatter in unity
- json serialization for unity game state

## When to choose
- you need robust serialization of Unity objects and structs in a game
- you want a fast, low-allocation alternative to BinaryFormatter or Unity's built-in JSON
- you need an extensible serializer with custom formatter support

## When to avoid
- you need serialization for non-Unity .NET projects where standard libraries like JSON.NET or protobuf-net fit better
- you need a schema-based wire format for cross-language interop
- your project requires minimal dependencies and a tiny footprint

## Facets
- artifact type: library
- maturity: active
- function: serialization
- domain: developer-tools
- platform: game-engine, cross-platform
- tags: unity, binary-serialization, json-serialization, save-data, game-data, game-development, c#
