Which one to pick
PostHog 39,757 stars
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 CX43 (cost-optimized) at Hetzner Cloud for $18.46 a month. Setting it up is roughly 16 hours of work, then 3 hours a month to keep it healthy.
