What it takes to run
None for hosted signup; self-hosting is an unsupported, resource-heavy multi-service stack requiring serious operations work
Where your data lives
The self-hosted stack splits analytics, transactions, queues and recordings across ClickHouse, PostgreSQL, Kafka, Redis and object storage; cloud data lives in PostHog's managed regions
Why fork PostHog instead of vibe-coding a Mixpanel clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Mixpanel, collect a small transparent event stream and build funnels and retention locally. The hard boundary is large-scale ingestion, identity handling, query engine, governance, and product expertise, plus data pipeline reliability and analytical depth.
