ClickStack Demo Days #1

The ClickStack Team

Each week, the ClickStack team demos what they've been working on. This is the first one we're putting out publicly - four demos covering trace improvements, SQL charting, and frontend debugging.

• Event Deltas — Filter attribute values directly in the trace distribution view and explore outliers by duration without needing to set up a comparison. Both changes merged this week.
• SQL Charts — Raw SQL charting now supports line, bar, pie, and number chart types, with SQL autocomplete and interval-aware queries for dashboard granularity. A ClickHouse-specific SQL parser is also in early development.
• Trace Timeline — New zoom/pan support on the timeline, bulk collapse of child spans via alt+click, and inline span durations that render on whichever side has more room.
• Source Maps (Enterprise) — Upload source maps via CLI, and HyperDX will automatically map minified JavaScript errors back to your original source — no more debugging compiled bundle output.
