Full Headless SDK — not just an API
Every competing loyalty app that advertises "headless support" really means they give you an API. You fetch customer points, redemptions, and tiers yourself, then build the entire UI from scratch — the widget, the panel, the rewards list, the checkout integration, the tier progress bar, the referral share modal.
Anchor ships a complete, pre-built widget that works on Hydrogen, Next.js, Remix, Gatsby, or any JavaScript framework. Three lines of code and the same experience your theme-based customers get is live on your headless store.
