4.7/5PostHog
All-in-one: analytics + replays + flags unified.
- First-hand testing note: Autocapture tracked 95% of our test events without writing a single tracking call. Session replays linked directly to funnel drop-offs. Genuinely replaced 3 separate tools in our stack. The trade-off: UI is more technical than Mixpanel.
- You want analytics + session replays + feature flags in one tool
- Open-source and usage-based pricing matter
4.6/5Mixpanel
Best pure analytics. Fastest funnel/retention UI.
- First-hand testing note: A PM with no SQL knowledge built a 5-step conversion funnel in under 2 minutes. The UI is the fastest in the category. The 20M events/month free tier is the most generous. The trade-off: you will need separate tools for session replay and feature flags.
- Product analytics is your only need
- Fastest funnel and retention UI matters

Quick Verdict
We instrumented the same B2B SaaS (12K MAU) with both for 30 days. Both accurate (data matched within 2%). PostHog gave us analytics + replays + flags in one dashboard. Mixpanel gave us the fastest analytics UI: but we needed Hotjar ($39/mo) + LaunchDarkly ($120/mo) alongside.
