I use Mixpanel for product event tracking across our web and mobile apps. The SDKs are lightweight and easy to integrate, and the tracking API is simple: one call with an event name and properties. Funnels, retention, and cohort reports are quick to build without SQL, so PMs and developers can answer questions themselves and spend less time on ad hoc queries. Live View and the event debugger let me check event names and properties from a local build in seconds during development or QA. That shortens our feedback loop, keeps tracking data clean, and helps make the funnels and reports PMs rely on accurate. I also get quick post-release visibility, can isolate drop-offs by properties like app version or platform, and can validate A/B experiments. The data export and raw API let us pull data into our own pipelines when needed. Setup was fairly easy: installing the SDK and sending the first events took under a day, and the docs and quickstart guides are clear. Once we had identity management set up, it was stable. Mixpanel is a strong, developer-friendly product analytics tool with easy SDKs and fast self-serve reporting.

I have been using Mixpanel for the past 4 years. The best thing is the experiment testing feature; it's very easy to create custom cohorts and analyse data for long periods of time.

Easy to share and view metrics. I like that it's very customizable.
