PostHog - Pros & Cons
Pros
- ✓Genuinely generous free tier — 1M events, 5K recordings, 1M flag requests monthly — means over 90% of companies use PostHog completely free
- ✓Unified platform combining 10+ products (analytics, replay, flags, experiments, surveys, error tracking, data warehouse) with shared user identification eliminates tool sprawl
- ✓Open-source with self-hosted option provides complete data ownership for regulated industries and privacy-conscious organizations
- ✓SQL-based query interface (HogQL) enables complex custom analysis impossible with drag-and-drop dashboard tools

Cons
- ✗Individual products lack the depth of best-of-breed alternatives — session replay isn't FullStory, error tracking isn't Sentry, surveys aren't Typeform

- ✗Non-technical team members face a steep learning curve with SQL-heavy analysis and developer-oriented interface design
