In short: Magnetar Apps builds two Shopify apps - Super Tags, which keeps product, order and customer tags accurate automatically with rules, and Super Checkout: Brand Styler, which styles checkout and customer accounts visually with no code. Super Tags works on all Shopify plans, Super Checkout: Brand Styler is exclusively for Shopify Plus, and both are billed through Shopify and include free trials. The answers below cover the details.
General
We build focused Shopify apps. Two right now: Super Tags, for rule-based tagging, and Super Checkout: Brand Styler, for checkout and customer-account branding. We are a small team building in Australia.
Super Tags works on every Shopify plan. Super Checkout: Brand Styler is built exclusively for Shopify Plus stores.
No. Both apps are no-code by default. Super Tags has optional code tags (Liquid) for power users, and Super Checkout: Brand Styler is fully visual with a live preview.
Super Tags
Products, orders, customers and discounts, using rules based on fields like title, vendor, inventory, price, order value, customer spend and discount usage.
No. Super Tags tracks provenance - it only ever removes tags it applied itself, and only when no active rule still wants them. Tags you added by hand are never touched.
Real-time plans tag via Shopify webhooks, usually within a few seconds. Manual sweeps and an optional scheduled reconcile also re-check your whole catalog so tags never drift.
Flow reacts to a single event when it happens. Super Tags reconciles a state across your entire catalog, including records that already exist, with safe removal and a live preview before anything runs.
Super Checkout: Brand Styler
Checkout, customer accounts and sign-in - colors, typography, corner radius, logos and custom sections - all with a live preview as you edit.
Yes. Super Checkout: Brand Styler is built exclusively for Shopify Plus stores, which get full access to Shopify's checkout branding and customization APIs.
No. Everything is applied through supported Shopify APIs - no theme hacks and no injected scripts - so platform updates roll through cleanly.
Checkout reverts to Shopify defaults. Your saved settings are kept for 30 days in case you reinstall.
Billing & trials
Yes. Every plan starts with a 7-day free trial.
Through Shopify's billing system, so app charges appear on your regular Shopify invoice. Prices are in US dollars, with 20% off annual billing.
Yes. Uninstall or downgrade at any time; access continues until the end of the current billing period.
Fees already charged are generally non-refundable except where required by law. If something went wrong, get in touch and we will make it right.
Privacy & security
Only what each app needs through Shopify's APIs: product, order, customer and discount records for Super Tags, and your branding configuration for Super Checkout: Brand Styler.
We only request Protected Customer Data where a feature you use needs it, use it solely to provide that feature, and handle it in line with Shopify's Protected Customer Data requirements.

The name
A magnetar is a neutron star with the strongest magnetic field in the known universe - trillions of times stronger than Earth's. It is barely the size of a city, but its pull reaches across space. Tiny core, enormous reach. (Yes, we think that is cool.)
Because a magnetar does exactly what good software should: it takes something small and quiet and gives it an outsized, invisible force. You never see the field - you only feel everything line up.
Same idea, less physics. Super Tags is the magnetic field for your catalog: set a rule once and it silently pulls every matching product, order and customer into place, then keeps them there as your store spins. Super Checkout: Brand Styler is the same quiet force on your checkout - one set of controls, and your whole brand snaps into alignment. Small core, store-wide reach. Just like the star.
