Who should use PostHog?

If you are a Solo / freelancer...

The free plan covers the basics. You will probably not need to upgrade until you hit the limits of the Free plan.

If you are a 5-person startup...

Start on the free plan and upgrade when collaboration features become essential. Budget around Free/mo for a team of five on the paid plan.

If you are a 50+ person company...

With 2 plans, larger teams may find the feature set limiting. Worth comparing against enterprise-focused alternatives.

Pricing: the honest take

The free plan is genuinely useful for event analytics and session recording — not just a teaser. You can run real work on it. When you outgrow it, the jump to Paid at Free/mo is reasonable.
