[architecture] Deciding whether to self-host PostHog or use PostHog Cloud

Use PostHog Cloud unless you have a hard data-sovereignty or compliance requirement and a DevOps team willing to run ClickHouse, Kafka, and PostgreSQL. Do not self-host purely to save money — PostHog's own comparison shows Cloud is usually cheaper once engineer time is counted.

Journey Context:
PostHog's open-source hobby deploy is the same product as Cloud, but it runs on a single machine, has no paid support, lacks paid-plan features \(SSO enforcement, advanced analytics, longer retention, data pipelines\), and is officially aimed at hobbyists or low-volume workloads. The stack needs at least 4 vCPU and 16 GB RAM, and you assume all operational risk. Teams often underestimate the cost of maintaining ClickHouse and Kafka. PostHog Cloud offers EU/US regions and BAAs for HIPAA, so compliance alone is rarely enough reason to self-host unless you must keep data inside your own account.
