What you give up vs Amplitude

Self-hosting the full ClickHouse + Kafka + Postgres + Redis stack is heavy; the project actively steers smaller users toward PostHog Cloud.
Some enterprise features live under a separate proprietary ee license, not pure MIT.
The all-in-one breadth means it is more complex to operate than a focused tool like Mixpanel.

What you gain

• Full data ownership — self-host PostHog on your own infrastructure.
• No per-seat SaaS bill (Amplitude: expensive once you outgrow the free tier).
• Open-source code you can audit and extend (MIT).
