Is PostHog actually free?

PostHog's cloud tier is free up to 1 million events per month — genuinely enough for most early-stage products. Self-hosted PostHog has no event limits and is free to run on your own infrastructure. Paid plans add enterprise features like SSO and priority support.

Can PostHog replace Mixpanel completely?

For most product analytics use cases yes — PostHog has funnels, retention analysis, user paths, cohorts, and dashboards comparable to Mixpanel. PostHog also includes session recordings and feature flags that Mixpanel doesn't, making it arguably a better full product analytics suite for many teams.

Is Plausible GDPR compliant without a cookie banner?

Yes, Plausible does not use cookies or collect personal data, making it GDPR, CCPA, and PECR compliant without requiring a cookie consent banner. This is a significant practical advantage over Google Analytics for European websites.
