Used For

• +**Your signup conversion is 12% but you don't know which step kills people** → Watch session replays of users who bounced, see exactly where they gave up
• +**You're A/B testing blindly with no idea what users actually clicked** → Track every button click, form field, and scroll depth with zero custom code
• +**Your support team gets the same "it's broken" tickets but can't reproduce bugs** → Send them session replays showing exactly what the user did wrong
• +**You built 6 features last quarter but don't know if anyone uses them** → Cohort analysis shows which features correlate with retention and revenue
• +Groups B2B users by company automatically - see which organizations are power users vs. tire-kickers

Best For

• >Your product has mystery drop-offs and you're tired of guessing what's broken
• >You're manually tracking funnels in spreadsheets and your CEO wants real numbers
• >Hit product-market fit but retention sucks and you need to see what users actually do

Not For

• -Solo founders without developers — you'll spend more time setting up events than building your actual product
• -Pure marketing teams who just want traffic numbers — Google Analytics is free and simpler for basic stuff
• -Enterprise teams needing complex compliance — self-hosting works but you're signing up for server maintenance

Pairs With

• *Slack (where PostHog sends alerts when users hit your activation milestones or drop off funnels)
• *Segment (if you want to send the same user events to PostHog plus your CRM and email tools)
• *Intercom (to message users who completed specific actions, like finished onboarding but never used the main feature)
• *Stripe (to track which user behaviors actually correlate with people upgrading to paid plans)
• *Linear (where your dev team creates tickets for the bugs you found in session replays)
• *HubSpot (for sales follow-up with users who hit certain engagement thresholds but haven't converted)

The Catch

• !Free tier sounds generous but you'll hit the 1M events limit faster than expected if you track everything
• !Backend event tracking needs actual coding — the "no-code" part only works for basic page views and clicks
• !Session recordings eat storage like crazy, especially if you have mobile apps or long user sessions

Bottom Line

Shows you the specific users who rage-quit at step 7 of your signup flow, complete with their email addresses.
