●●SolidWizardryNiche Gem
Xcode GPU frame debugging for WebGL/WebGPU—finally fills the native profiler gap.
Strengths
- •Automates WebKit/Chrome GPU trace capture with Metal System Trace output in Xcode
- •Supports both WebGL frame replay and WebGPU timelines with swappable runtimes
- •Handles iframe-blocked sites via in-page WebGL injection mode
Weaknesses
- •macOS-only; Windows and Linux developers cannot use this tool
- •Requires initial WebKit build which is slow, raising onboarding friction

Post Description
I hacked together a tool to inspect the GPU pipeline for any WebGPU / WebGL app in Xcode.
Xcode's native GPU debugger is awesome and I really miss it when building web apps :)
