## What it is
GAPID is a collection of tools for recording, inspecting, tweaking, and replaying calls made by an application to a graphics driver, supporting OpenGL ES on Android and Vulkan on desktop. It includes a GUI client for stepping through draw calls and inspecting state, plus a command-line tool (gapit) for capturing and analyzing traces.

## Use cases
- trace and replay graphics API calls from an Android app
- debug Vulkan application rendering frame by frame
- inspect shaders, textures, and geometry in a captured frame
- step through draw calls to see how a frame is composed
- tweak shader source and see the effect on the rendered frame
- capture and analyze graphics traces from the command line
- profile replay performance of graphics commands

## When to choose
- you need to debug OpenGL ES rendering on an Android device
- you want to inspect and replay Vulkan command streams on desktop
- you need to visualize textures, shaders, and framebuffer state at any point in a frame
- you want a free, open-source alternative to proprietary GPU debuggers

## When to avoid
- you need actively maintained Android GPU profiling - use Google AGI instead
- you need to debug APIs other than OpenGL ES or Vulkan
- you require replay on a different device than the one used for tracing
