“Get started - free”
Generic free-tier CTA that could belong to any SaaS product. For a multi-product platform, "get started" doesn't tell the visitor which product they're starting with. The ambiguity creates decision paralysis — especially for visitors evaluating PostHog as a replacement for one specific tool (e.g., Hotjar for session replay).
“Try product analytics free — no credit card, no data limits for 1M events/mo.”
Names the specific product (analytics), removes the two biggest friction points (credit card + data caps), and anchors on the generous free tier. Visitors who came for a specific use case now have a clear entry point.
