Back in stock
Collect email and SMS waitlists when products sell out. Notify subscribers when inventory returns.
Built for Shopify themes
Stockly
Help shoppers find the right moment to buy — waitlist sold-out items, take PreOrders, and show low-stock urgency without leaving your theme.
Open in Shopify Admin
Enter your .myshopify.com domain to install Stockly or open it if it is already installed.
What merchants get
Theme App Extension widgets for Back in stock, PreOrder, and Low stock — configured in Admin, shown on your storefront.
PreOrder
Keep selling with Continue selling when out of stock. Badges, offer selectors, and mixed-cart notices on cart.
Low stock
Show urgency messages like “Only X items left” under Add to cart — with colors and copy you control.
Theme App Extension
Embed Stockly and Pre-order Offer Selector from the theme editor. No custom Liquid required for the core widgets.
Plans that scale
Free on development stores, then Standard or Advance — unlock collection/home widgets, mixed cart alerts, scheduling, and deeper customization as you grow.
Shop-scoped & compliance ready
Data stays tied to the installing shop. Mandatory compliance webhooks are implemented for uninstall and GDPR topics.
Live in three steps
Install the app, enable the embed, and turn on the modules you need.
Install on your shop
Log in with your shop domain. Shopify handles OAuth. Stockly stores a shop-scoped session — not shopper accounts.
Enable the app embed
In the theme editor, turn on the Stockly app embed so widgets can appear on product, collection, and cart surfaces.
Activate modules
Turn on Back in stock, PreOrder, and Low stock from the dashboard, then customize buttons, badges, and alerts.
