X Broadcast Metrics

About

Track live viewer counts, peak audiences, and growth rate on X (Twitter) broadcasts and Spaces — all in a lightweight floating widget that stays out of your way.

Whether you host broadcasts, study audience behavior, or just like watching the numbers tick, X Broadcast Metrics gives you real-time visibility that the X interface doesn't.

WHAT IT DOES
A small, draggable widget appears on every X broadcast or Spaces page you visit, showing:
• Live viewer count (animated)
• Peak viewers this session
• Change since last update
• Growth rate over the last 1, 5, and 10 minutes
• Mini sparkline charts of every metric
• Session duration and sample count

DASHBOARD
Click the toolbar icon to open a full dashboard with every broadcast you've tracked — sortable by peak viewers, broadcaster, time, or sample count. Search across broadcasters and broadcast IDs. Live sessions are highlighted.

CUSTOMIZE
• 6 themes (Dark, Light, Neon, Ocean, Transparent, Ghost)
• 3 view modes (normal, compact, wide)
• Sparkline smoothing and curve options
• Configurable default chart, time range, and metric
• Optional tick sound on every viewer update
• Set a custom alert threshold and get notified when viewers reach your target
• Previous-day overlay so you can compare today's growth against yesterday at the same time of day

EXPORT
One-click CSV or JSON export of all your collected data. Take it into a spreadsheet or your own analysis pipeline.

PRIVACY-FIRST
Everything is stored locally in your browser. No remote server. No analytics. No tracking. No account required. Your data never leaves your device, and you can wipe it all from the settings page with one click.

PERMISSIONS
The extension only runs on x.com and only reads the same broadcast data that X already shows you. Nothing is uploaded, shared, or sold.

HOW TO USE
1. Pin the extension to your toolbar (recommended)
2. Visit any live X broadcast 
3. The widget appears automatically — drag it where you want
4. Click the toolbar icon any time to open the full dashboard

Built for broadcasters, social-media managers, researchers, and anyone curious about audience dynamics on X.
