When PostHog wins

  • Technical product teams that want one tool covering analytics, experiments, replay, and surveys
  • Startups under 1M events per month, where the free tier covers the entire stack
  • Companies committed to open-source infrastructure who want the option to self-host

Where PostHog is the wrong fit

  • Marketing-only teams who need attribution and campaign analytics (Mixpanel or GA4 fit better)
  • Enterprises with strict procurement that requires a SaaS-only vendor with no self-hosted option in scope
  • Non-technical users who cannot navigate event-based analytics UIs and SQL-style insights

When Surfer SEO wins

  • Content marketers writing for SERP visibility
  • Bloggers and freelancers wanting AI-assisted SEO content briefs
  • Agencies producing 10+ articles per month for multiple clients

Where Surfer SEO is the wrong fit

  • SEO professionals doing keyword research at depth (use Ahrefs or SEMrush)
  • Enterprises that already have Conductor or similar workflow tools
  • Brands with no content production team
