An SRE has five dashboards open during an incident. Each one pulls millions of trace rows. Today's browser stutters or drops to 20 fps when a panel re-aggregates.
The JavaScript aggregation layer beneath the dashboard. Same filter, group and sort - running on the GPU when that's faster, on a worker when it isn't, transparently.
Datadog- or Grafana-grade dashboards in a browser tab without per-refinement server round-trips. The UI stays at 60 fps while the dataset grows.
Hadron is not claiming the GPU is fastest. It picks the right backend for each operation - sometimes GPU, sometimes Worker, sometimes CPU, sometimes a categorical refusal. The result is the same; the cost is different. Watch the Dispatch evidence panel beside each app: every interaction prints which path was chosen, the score that drove the choice, and a one-line reason.
