🇬🇧 UK💷 GBP📊 Comparison🔒 UK GDPR⚖️ UK Law

PostHog (self-hosted or EU cloud) is the right default for UK regulated software: EU data residency, open-source (can be audited), session replay included, and the only major product analytics tool that can be fully self-hosted in AWS eu-west-2 (zero third-party data processing). Mixpanel and Amplitude are right when the team values their specific analytics features and is comfortable with US-hosted data transfer mechanisms. For NHS and FCA regulated software: PostHog self-hosted in eu-west-2. UK product analytics platform choice affects UK GDPR data residency, PECR cookie consent requirements, and NHS DTAC compliance. Here is a 2025 UK comparison.
