Loyalty Interchange Protocol vs The Stampit

Loyalty Interchange Protocol (LIP) is an open-source loyalty platform and vendor-neutral transaction protocol for restaurant technology teams that own integration work. Its checkout lifecycle includes member lookup and enrollment, balances and ledger history, order evaluation, accrual, redemption, reversal, and refund-safe adjustments. Its restaurant order model represents items, modifiers, discounts, fees, taxes, tips, tenders, and totals across channels such as drive-thru, kiosk, web, mobile, pickup, delivery, and catering. Supported program types include points, visits or stamps, wallet credit, paid membership, and hybrid multi-account programs.

The `/platform/v1` API covers profiles, consent, behavioral events, segments, campaigns, connectors, imports, analytics, and attribution. The maker provides an Apache-2.0 reference stack for self-hosting with Docker Compose or Node.js 22 and newer. Storage described includes SQLite-backed local storage and tenant-scoped PostgreSQL for multi-instance use. Customer sign-in remains external. LIP 0.2.0 is described as pre-1.0 infrastructure, not a turnkey no-code marketing service; CSV member imports are limited to 1 MiB and 1,000 rows.

The Stampit is a digital loyalty-card service for cafés, restaurants, and pubs. Customers collect stamps with a tap in the app instead of carrying paper cards, while businesses operate the program through a secure dashboard in any modern browser. Merchants can create Magic Codes for online and takeaway orders, including batches of unique codes sent physically or digitally. Campaigns can target customer groups by behaviour, use custom rewards, and schedule offers. Insights reports stamps issued, repeat-visit frequency, reward redemptions, and customer engagement in real time. Customers can pre-pay for treats, redeem vouchers in-store, or gift them by phone number. The maker says no complex technology or integrations are required, and rewards can be validated without Wi-Fi or Bluetooth. Android, iOS, and web access are supported. Basic costs £24.99 per month, Growth £34.99 per month, and Advanced £54.99 per month; each plan covers one location.
