MangoHud

What MangoHud is

MangoHud is a Linux overlay for Vulkan and OpenGL applications that displays performance and hardware readings while a program runs. Its configurable metrics include FPS, frame timing, CPU and GPU load, temperatures, clock speeds, fan speed, power, memory, and network throughput. Configuration can be applied globally, for a particular application, through environment variables, or with presets. An FPS limiter can take multiple comma-separated values. MangoHud can save frame data to log files, and its local `mangoplot` script can visualize and compare benchmark logs. Users can also batch upload logs to FlightlessMango.com for frametime graphs and summaries; uploaded benchmarks are public. Steam games can launch with `mangohud %command%`, while Lutris games can use `mangohud` as the command prefix. Gamescope use needs the companion mangoapp and the command `gamescope --mangoapp -- %command%`; standard MangoHud use with Gamescope is unsupported. Installation options include pre-packaged binaries, packages documented for Arch, Debian, Ubuntu, Fedora, Solus, and openSUSE, Flatpak, or building from source with Meson and Ninja. The project is MIT licensed and points users to Discord and its GitHub issue tracker for support.

Who it suits

MangoHud suits Linux users who want performance and hardware readings overlaid on Vulkan or OpenGL applications, including Steam and Lutris games. It also fits users who want to log frame data and compare benchmark runs locally or through public online visualizations.

Limits

MangoHud is free, and the supplied facts give no free-plan quota or feature limit. Standard MangoHud use with Gamescope is unsupported; Gamescope requires mangoapp and its specific command.

Getting started

1. Visit the MangoHud GitHub project.
2. Install a documented package or Flatpak, use a pre-packaged binary, or build from source with Meson and Ninja.
3. For a Steam game, add `mangohud %command%` as its launch option.
4. For a Lutris game, add `mangohud` as the command prefix.
5. For Gamescope, use mangoapp with `gamescope --mangoapp -- %command%`.
6. Adjust configuration globally, per application, through environment variables, or with presets.

Verdict

Choose MangoHud if you want a configurable Linux overlay for Vulkan or OpenGL performance and hardware readings, with frame logging and benchmark visualization. Gamescope users need to use mangoapp with its required command, and uploaded online benchmarks are public.
