Marsello
Building a basic e-commerce loyalty widget and points ledger takes a few days. However, Marsello's core strength is bidirectional, real-time sync across physical POS hardware (Lightspeed, Square, Clover) and e-commerce platforms. Maintaining custom API integrations against third-party retail POS devices creates massive developer overhead.

- VIP tier status assignment and tracking
- E-commerce loyalty widget popup UI
- Automated email triggers based on customer order actions
- Basic referral link generation and tracking
what you lose
- Turnkey integrations with Lightspeed, Square, Clover, and Shopify POS

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.
