How best to find concurrent users in MixPanel?

Hi Shane, Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support. If you have follow-up questions for this thread, please tag me again with your question: @kapa.ai <follow-up question> 👋

The knowledge sources don’t describe a built‑in “concurrent users” metric or a recommended recipe for it, so I can’t give a definitive, Mixpanel-documented method.What is documented is: - Mixpanel can show you DAU/WAU/MAU and unique users over time in Insights, but that’s based on users who did an event in a time window, not true concurrency at a point in time. [Users metrics; MAU blog] - Sessions can be computed from your events, and you can analyze “Session Start” / “Session End”, total sessions, average session length, and sessions per user in Insights, Funnels, and Flows. [Sessions in reports]Given that, the closest Mixpanel-native approximation to “concurrent users” (without any undocumented tricks) would be: 1. Enable Sessions on your project so Mixpanel derives “Session Start” and “Session End” events and “Session Duration (Seconds)”. [Sessions in reports] 2. Use an Insights report on “Session Start” (or “Session End”) and: - Count Sessions (via the aggregation dropdown) to see how many sessions are active in a period. - Break down or filter by “Session Duration (Seconds)” to understand how long sessions last. [Sessions in reports]From these, you can reason about approximate concurrency (e.g., many overlapping long sessions imply more concurrent users), but the docs do not show a direct way to query “number of users simultaneously online at time T”.If you need exact concurrent counts at specific timestamps, the knowledge sources do not describe a supported, out‑of‑the‑box method for that in Mixpanel.
