OpenLoyalty
OpenLoyalty provides an infrastructure-grade API engine for processing millions of events, maintaining immutable points ledgers, and evaluating complex rule trees across e-commerce and POS systems. While basic spend-for-points functionality is trivial to code, building a fault-tolerant engine that handles partial refunds, race conditions, retroactive tier adjustments, and non-technical campaign builders is a massive sink of developer resources.

- Static spend-based tier status assignments
- Simple digital reward catalog and point redemptions
- Shopify discount code creation via API on reward claim
- Customer-facing points balance and transaction history API
