## What it is
apitrace is a set of tools for tracing OpenGL, OpenGL ES, Direct3D, and DirectDraw API calls to a file, then replaying and inspecting them. It supports state inspection, framebuffer/texture viewing, trace editing, and performance profiling of recorded traces.

## Use cases
- trace OpenGL API calls from an application
- replay a captured graphics trace on another machine
- inspect OpenGL or Direct3D state at any call
- debug rendering issues in a game or 3D app
- profile performance of graphics API calls
- view framebuffers and textures from a trace

## When to choose
- debugging OpenGL or Direct3D rendering problems
- capturing and replaying graphics API calls for bug reports
- analyzing frame performance of graphics workloads

## When to avoid
- tracing Vulkan (use vkTrace or RenderDoc instead)
- needing actively developed features, since maintenance is minimal
- debugging non-graphics APIs

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: developer-tools, graphics, simulation
- domain: graphics, developer-tools, performance
- platform: windows, cli, cross-platform
- tags: graphics-debugging, api-tracing, opengl, direct3d, replay, frame-analysis, game-development, linux, macos
