Kafka, ClickHouse, PostgreSQL, Redis and several workers. PostHog itself now discourages self-hosting below a substantial scale, and the sizing here reflects that honestly.
At 10 people it needs 10.2 GB of memory and 62 GB of disk, which fits the Starter 16 GB at VPSServer for $84.00 a month. Setting it up is roughly 16 hours of work, then 3 hours a month to keep it healthy.
