Where to find it

  • Localhost: /quality-activity-heatmap.html?repo=<id>

  • Sidebar: Level up Activity heatmap

What it does for you

Cadence at a glance.One cell per hour-of-day × day-of-week. Darker = more sessions or spend. You see the shape of your week without scrolling through a session list.
Late-night and weekend concentration, surfaced as percentages.A Work-life balance panel reports what share of your sessions and spend land in late-night hours (00:00 to 05:59) and on weekends (Saturday and Sunday). The grid cells themselves are shaded by intensity only. The pattern shows up before you feel it.
One repo, or several merged.The grid covers one repo, resolved from the tab you opened it in. Pass the API a repos parameter to merge several repos into a single grid. The grid bins by hour and day only, so there is no per-developer view.

Configure

Nothing - built from the same session telemetry as Activity ledger. Honors the same privacy mode.

Use it well

Open at the end of each sprint. If the late-night band is warmer than two sprints ago, name it in the retro. The data is more honest than the standup self-report.
