Fathom
Free forever plan with unlimited meetings and core features makes it accessible for individuals and small teams

No GraphQL API or official SDKs limits flexibility for custom integrations and workflows
Advanced team features like custom AI summaries and admin controls require paid Business plan
PostHog
Usage-based pricing with no per-seat fees—unlimited team members and typically 60-80% cheaper than Amplitude or Mixpanel at scale
Generous free tier (1M events, 5K replays monthly) allows most startups to use it indefinitely without paying
All-in-one platform eliminates data silos by combining analytics, session replay, feature flags, A/B testing, and surveys in one tool
Open-source with self-hosting option provides complete data ownership and transparency, ideal for regulated industries
Developer-centric interface has a learning curve for non-technical product managers and marketers who may need to wait for engineering support
Self-hosting requires DevOps expertise and ongoing server maintenance, adding operational overhead
Usage-based pricing can become expensive at high scale—session replay costs particularly add up with millions of recordings
