Description

See what your stream is really doing. Capture HLS/M3U8 manifests, inspect qualities, and replay streams. StreamScope is a developer tool for inspecting and debugging HLS video streams in the browser. It detects HLS (.m3u8) manifests loaded by pages you enable, lets you inspect stream variants and qualities, replay streams, and export streams to MP4 for offline analysis. All processing happens locally and only after user interaction. StreamScope is intended for development, testing, and educational use. It does not bypass DRM, paywalls, or content protections. No tracking. No data leaves your device.
