PerfGuardian – Runtime Performance Monitor & Spike Detector
PerfGuardian is a lightweight runtime performance monitoring tool for Unity projects.
It helps developers detect FPS drops, GC spikes and memory issues automatically while the game is running.
Unlike the built-in Unity Profiler, PerfGuardian is designed to work directly inside runtime builds with minimal overhead, making it ideal for production testing and real-device diagnostics.
KEY FEATURES
• Real-Time FPS Monitoring
Track frame rate and frame time directly in-game.
• Automatic Spike Detection
Automatically detect:
- Low FPS events
- Frame hitches
- GC allocation spikes
• Memory Monitoring
Monitor Mono memory, total allocated memory, and reserved memory usage.
• JSON Event Logging
Export structured performance logs in JSON format for external analysis or debugging.
• Lightweight & Production Safe
Designed to run with minimal runtime overhead.
• Cross-Platform Support
Works in Unity Editor and standalone builds. Logs are saved to persistentDataPath.
• Built-In Stress Test Demo Scene
Includes demo tools to simulate object spawn stress, GC allocation spikes, and UI rebuild spikes for testing.
WHY PERF GUARDIAN?
When the Unity Profiler is too heavy or impractical for runtime builds, PerfGuardian keeps watch.
It is not a full profiler replacement — it is a lightweight performance watchdog designed to alert you when something goes wrong.
IDEAL FOR
• Indie developers testing builds on real devices
• Runtime diagnostics in production builds
• Detecting performance regressions
• Monitoring FPS and GC behavior during gameplay
• Lightweight performance validation before release
TECHNICAL DETAILS
• No third-party dependencies
• Minimal allocations
• Clean namespace structure
• Runtime-safe implementation
• Compatible with Unity 2021+ (or your target version)
DOCUMENTATION INCLUDED
• Quick start guide
• Setup instructions
• Changelog
• Usage examples
