Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Instapage

  • Create tier limited to 15,000 monthly unique visitors; scaling requires upgrading to Optimize tier
  • Optimize tier offers only 30,000 or 50,000 visitor tiers, requiring Convert (custom pricing) for higher volumes
  • Pricing significantly higher than competitor Leadpages, which offers unlimited traffic starting at $99/month
  • Advanced personalisation and heatmaps only available in Convert (enterprise) tier
  • Annual billing required for 20% savings; monthly billing incurs full price

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
