our call

Start with Plug in SEO — highest vibe code, weakest moat.

Justuno

Building a high-performance JS trigger script that renders popups and captures emails into Klaviyo takes less than two weeks. However, replacing Justuno completely requires rebuilding a full drag-and-drop visual design canvas and replacing their managed agency CRO services.

you can rebuild

  • Exit-intent and timed popups
  • Basic email and phone capture forms
  • Targeting rules (URL parameters, cart value, device type, new vs returning)
  • Sticky bars and slide-in notifications
  • Static discount code presentation

what you lose

  • Drag-and-drop freeform canvas builder for complex multi-step modal designs
  • Managed "Done-For-You" CRO agency services and dedicated account managers
  • Pre-built library of hundreds of high-converting storefront templates
  • Proprietary AI product recommendation engine widgets
  • Built-in instant email and SMS verification at the point of capture

real moats

  • Deep ecosystem integrations with tier-1 enterprise ESPs (Klaviyo, Attentive, Postscript) and agency partner networks.
  • Extensive visual template library and drag-and-drop design studio built for non-technical conversion rate optimisers.
  • Managed service tiers where human CRO strategists design and maintain campaigns for high-volume enterprise stores.

  • Pre-built UI for visual bulk-redirect editing
  • Automated email notifications on link decay or speed score drops
  • Maintenance across changing Shopify theme standard updates
  • Immediate turn-key compatibility across hundreds of third-party Shopify themes
