## What it is
MangoHud is a Vulkan and OpenGL overlay that displays real-time performance metrics like FPS, frametimes, CPU/GPU load, and temperatures in games and applications. It also supports FPS logging with visualization via FlightlessMango.com or the local mangoplot tool.

## Use cases
- show fps overlay while gaming on linux
- monitor gpu and cpu usage in vulkan games
- log frametimes for benchmarking
- track gpu temperatures during gameplay
- overlay performance stats in opengl applications
- visualize benchmark results online

## When to choose
- you game on Linux and want an in-game performance overlay
- you need FPS/frametime logging for benchmarking
- you want per-game configurable HUD metrics via environment variables

## When to avoid
- you need a full system-wide monitoring dashboard rather than a game overlay
- you are on Windows and need a native solution
- you need GPU profiling with deep hardware counters rather than a HUD

## Facets
- artifact type: library
- maturity: active
- function: monitoring, benchmarking, graphics
- domain: gaming-tools, graphics, performance, operating-systems
- platform: cpp
- tags: vulkan, opengl, fps-overlay, hud, gaming, frametime-logging, system-monitoring, linux
