Stats for geeks
Everything below is read from what is still in the database right now — so it is “all time” for the data we have not pruned yet. Usage pings and some analytics rows age out on a schedule; older sessions may disappear too. Country is best-effort (from the client network path when available); private addresses and missing lookups show as unknown. No individual IPs or session links appear here. Aggregates are recomputed periodically and cached in Redis to keep this page cheap.
Figures 2026-07-28 08:25:22 UTC. Aggregates reused for up to 180s (Redis/APCu cache).
All-time usage (what we still have)
“How many times has this been used” is approximated by logged interactions: starting a session, opening a controller, and a monitor staying connected (demo is excluded from logging).

Where users are (usage pings)
Every row is a coarse, anonymous ping our servers kept: session starts, controllers, and live monitors together. Percentages below are each country’s share of every usage row still stored; only the busiest countries appear in the table (the rest exist but are omitted here).
| Country / region | Logged events | Share of usage log |
|---|---|---|
| Germany | 4 | 100.0% |
Top 40 countries by volume shown; each % row is relative to every stored ping (“Unknown” includes private IPs and lookups we could not enrich).
Controller opens (historical log)
Separate long-lived table of controller page loads. Row count can differ from “Controller opened” pings above due to deduplication and retention rules.
- Stored controller-load events
