Visual builder
Buyers pick parts, colors and add-ons step by step and watch a layered preview update with every choice, on any phone.
Rules and conditional logic
Rules that keep every design buildable
Real products have parts that only fit together in certain ways. Rules let you describe that once, so buyers never reach a combination your workshop cannot make.
Conditions on any answer
A rule starts with a condition: an answer is picked, is not picked, is one of a list, or a text field is filled. Combine conditions with all, any and not. Conditions can point at questions before or after the one they affect.
Four actions
Hide a question, hide a single answer, force an answer, or set a different price for an answer while the condition holds. A typical example: when the buyer picks a bundle, the engraving inside it costs half.
One engine, two places
The rule engine exists in JavaScript for the storefront and checkout, and in PHP for the backend. Both run the same shared test fixtures and must produce exactly the same result, so the order your workshop sees always matches the preview the buyer saw.
Caught before publishing
Rules that keep switching each other back and forth, or point at answers that no longer exist, are reported when you publish instead of surfacing as a broken page.
More features
Pricing and checkout
Live prices in the builder and native checkout pricing through a Shopify Cart Transform function. No hidden price variants cluttering your catalogue.

API and integrations
A read API for orders, designs and published customizers, and signed webhooks the moment a design is ordered.
Analytics
A funnel from builder opened to ordered, how far buyers get through the steps, and which answers bring in orders and revenue.
Currencies and languages
Labels per language, prices in the buyer's currency with per-market rounding, and the same math in the builder and at checkout.
Theming
A small, fast builder designed at 360 px first. Styled with CSS tokens and theme editor settings, with stable class names for anything else.
