## What it is
Fast Script Reload is a Unity plugin that hot-reloads C# script changes into a running play-mode session without full domain reload or recompilation. It compiles only changed code on the fly, letting developers iterate rapidly without leaving play mode, with an optional paid add-on for hot reload on device builds.

## Use cases
- hot reload c# scripts in unity without leaving play mode
- iterate on game code without waiting for domain reload
- test code changes instantly while the game is running
- avoid reentering play mode after every small code change
- live reload scripts on an android build or quest headset
- run one-off code on hot reload to set up a test scenario

## When to choose
- you develop in Unity and lose time to script recompilation and domain reloads
- you want to tweak gameplay code live during play sessions
- you need to iterate on code running on device or VR headsets (with the Live Script Reload add-on)
- you use any code editor and want editor-agnostic hot reload

## When to avoid
- you need to ship the tool in production builds - it is a development-time utility
- your project relies on patterns incompatible with hot reload limitations
- you work outside Unity - this is Unity-specific
