by PostHog

PostHog is product analytics, session replay, flags, experiments, error tracking, logs, and a warehouse in one person model. Autocapture if you want volume; named events when the question is real. HogQL when a trends chart is the wrong shape. Cloud or self-host. MIT, except ee.

Not Google Analytics with extra buttons. I keep it for product questions — who dropped, which flag, which session — without shipping the same events to five vendors. posthog.com, source PostHog/posthog. Generous free Cloud tier. The MCP talks to the same project.
