Diagnosing live stream issues (latency drift, CDN cache misses, broken manifests, SCTE-35 ad splices) required switching between packet analyzers like Wireshark that lack video context, or tools like ffprobe and curl that download multi megabyte media chunks just to inspect basic container metadata. There was no lightweight, terminal-native tool designed specifically for real time broadcast and OTT stream health.

Run `streamtop <STREAM_URL>` against any live HLS, DASH, or MPEG-TS feed. In the TUI, inspect the real-time TTFB network breakdown (DNS, TCP, TLS, TTFB), CDN edge cache hit/miss status, audio track metadata, and cross segment GOP keyframe cadence without wasting bandwidth.

Zero payload wire probing: instead of downloading full 5-10 MB media segments, streamtop uses targeted HTTP Range requests (~2-64 KB) to decode fMP4 atoms and MPEG-TS headers directly on the wire. Built with Tokio and Ratatui, it runs at sub-millisecond latency with near-zero CPU and memory overhead.

Deeper Low-Latency HLS (LL-HLS) part inspection, automated PTS audio/video sync drift measurement, and native packaging completion across official package repositories.
