## What it is
Alchemy is a Unity library providing attribute-based Inspector extensions, Hierarchy and EditorWindow enhancements, and source-generated serialization for types Unity doesn't natively support (dictionaries, hash sets, nullable types, tuples). It requires no base-class inheritance, unlike Odin Inspector.

## Use cases
- customize Unity Inspector fields with attributes
- serialize dictionaries and hashsets in Unity
- build custom Unity EditorWindows quickly
- improve Unity Hierarchy window usability
- avoid paying for Odin Inspector
- show SerializeReference type dropdowns in Inspector

## When to choose
- you want Odin-like Inspector customization for free in Unity
- you need to serialize unsupported C# types and edit them in the Inspector
- you want attribute-driven editor tooling without base classes

## When to avoid
- you're not using Unity 2021.2 or later
- you need runtime serialization beyond the Unity editor workflow
- you require Odin's full feature set or support guarantees

## Facets
- artifact type: library
- maturity: active
- function: serialization, ui-components, editor, plugin-system
- domain: developer-tools
- platform: game-engine, cpp
- tags: unity, inspector, source-generator, hierarchy, editorwindow, attributes, game-development
