I built ThresholdIQ after getting paged at 3am because of badly tuned alert thresholds. The classic problem: set them too low → alert fatigue, set them too high → miss critical issues.

The tool lets you test thresholds on historical data before deploying: - Upload CSV/Excel or paste from clipboard (even works with PDFs!) - Set warning/critical/emergency thresholds - See exactly which alerts would have fired - Visualize on a timeline - Export reports

Key features: 100% client-side - your data never leaves your browser Handles millions of rows using Web Workers Visualize ALL metrics - set rules only for the ones you want to monitor Interactive tutorial built in Works offline after first load

NEW: Paste Data feature - copy tables from anywhere (PDFs, Excel, web pages) and paste directly. No file upload needed.

COMING SOON: Google Sheets integration

Tech stack: Vanilla JS, Web Workers, Chart.js. No frameworks, no server.
