Spector.GPU — WebGPU Inspector

Capture and inspect WebGPU frames on any website

Spector.GPU is a WebGPU frame debugger for Chrome. Open a WebGPU application, select Capture Frame, and inspect its queue submissions, render and compute passes, draw and dispatch calls, WGSL shaders, pipelines, bind groups, buffers, textures, and visual output. Captures stay in local extension storage and can be deleted from the result viewer. Spector.GPU contains no telemetry and does not send capture or browsing data to a project-operated service. Highlights: - One-click WebGPU frame capture - Render-pass, compute-pass, draw, dispatch, and state inspection - WGSL shader and pipeline inspection - Buffer, texture, sampler, bind-group, and resource cross-references - Texture previews, buffer hex views, and interactive 3D mesh inspection - Local-only storage with no analytics or telemetry Current support: Chrome and Chromium-based Edge 113 or newer. Some depth/stencil, compressed, multisampled, and 3D texture formats cannot be read back for previews.
