The short version

  • Only Hotjar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Hotjar website performance impact - Hotjar tracking code can cause noticeable slowdowns affecting site speed and Google rankings; Mollie non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • They diverge on capability: Hotjar covers Heatmaps, Mollie covers Local payment methods.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Hotjar

  • Website performance impact - Hotjar tracking code can cause noticeable slowdowns affecting site speed and Google rankings
  • Session recording limits - free and lower-tier plans have monthly session recording caps that must be sampled above the limit
  • Inaccurate heatmaps on dynamic pages - heatmaps fail to display correctly on pages with modals, sticky navigation bars, and pop-up overlays
  • No mobile app - only web-based access available
  • Not real-time analytics - includes slight data processing delay

Mollie

  • Non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • Coverage is built around European methods, so if you expand into Latin America or Southeast Asia you will need a second processor and a second reconciliation process rather than extending Mollie.
  • The in-person Pro plan requires a one-year contract and charges 20 pounds a month per additional terminal, so a shop with four tills pays 80 pounds a month in terminal fees before any transaction cost.
  • Mollie offers no interchange-plus option publicly, so large merchants cannot see or benefit from falling interchange the way they could on a cost-plus contract with an acquirer.
  • The developer tooling and reporting are lighter than the largest processors, so finance teams that want detailed fee breakdowns or granular reconciliation exports often end up building that layer themselves.
