our call
Start with Impact.com — highest vibe code, weakest moat.
Dynamic Yield
Basic product recommendation widgets or static rule-based banners can be built with Postgres vectors and edge scripts. However, replacing Dynamic Yield requires building real-time multi-armed bandit routing, sub-50ms global edge decisioning, and a WYSIWYG campaign builder for non-technical marketers. Attempting a complete custom clone will paralyze engineering.
you can rebuild
- Basic vector-based product recommendation carousels
- Rule-based dynamic hero banners based on query parameters or device type
- Simple 50/50 split-testing logic on frontend routes
- Basic clickstream event tracking (page views, cart additions, purchases)
- User segment assignment based on order history thresholds
what you lose
- Multi-armed bandit algorithms for automatic real-time conversion optimization
- Sub-50ms global edge worker execution to prevent page layout flicker
- WYSIWYG visual campaign editor for non-technical marketing staff
- Cross-channel profile stitching across web, mobile apps, and ESPs
- Access to Mastercard aggregated consumer spending datasets and audience targets
real moats
- Sub-30ms global edge decisioning infrastructure
- Mastercard proprietary consumer spend data integrations
- Deep template-level integration lock-in across complex retail frontends
