Project case study

Project Jaunt Case Study

A browser diagnostics project for Twitch playback logging, CDN timing, buffer health, throughput signals, and exportable troubleshooting reports.

Project snapshot

Diagnostics without changing playback behavior

Project Jaunt is the working home for Twitch Diagnostics Console, a browser add-on project by John Finnerty. The project observes playback and network signals so someone troubleshooting can understand or report buffering and routing problems.

Diagnostics problem

Make playback issues easier to inspect and explain

Buffering, latency, dropped frames, and CDN routing issues can be difficult to describe clearly. Project Jaunt explores a practical troubleshooting surface that turns browser observations into visible logs and exportable evidence.

Playback health signals

The add-on records buffer-ahead, live-edge gap, playback state, dropped frames, and recent throughput.

CDN request context

The project tracks connected video CDN hosts, request counts, response times, status codes, byte counts, and delivery type.

Exportable reports

The prototype includes local JSON diagnostics export paths for troubleshooting or support conversations.

Privacy and troubleshooting boundaries

Observe signals; do not alter the stream

The project documentation is clear that Twitch Diagnostics Console is for diagnostics only. It does not change Twitch playback, force CDNs, proxy traffic, bypass Twitch behavior, or send diagnostics to a server.

Local diagnostics

Diagnostics are stored locally in memory while the Twitch tab is open.

User-controlled exports

JSON exports are created only when the user chooses copy or download.

Versioned add-on code

The source archive preserves browser add-on code, README instructions, packaging artifacts, and documentation in version control.

Capability evidence

Skills reflected by the project

Project Jaunt supports a professional profile around browser tooling, diagnostics, support workflows, privacy-conscious logging, export design, JavaScript, and clear technical documentation.
