Rulefy

A no-code rules engine for Shopify checkout. Control cart validation, discounts, and payment methods — all powered by Shopify Functions.

Cart & Checkout Validation. Restrict products by customer tag, enforce quantity limits, require bundle dependencies, block PO boxes, set minimum cart totals, and more.
Dynamic Discounts. Create tiered collection discounts, volume-based pricing, spend thresholds, and tag-based exclusions — all configured through an intuitive UI.
Payment Customization. Hide or show payment methods based on customer tags, order history, or custom conditions. Block COD for first-time buyers or restrict methods to wholesale customers.
