Back in Stock is one of the most popular Shopify apps designed to help eCommerce brands recover lost sales. As the name suggests, it allows merchants to automatically notify their customers the moment an out-of-stock product becomes available again. It's a simple way to re-engage interested shoppers and drive conversions without any manual follow-ups.
Running out of stock is a common challenge in eCommerce. Not only does it disappoint potential buyers, but it also directly impacts your revenue. If a product page doesn’t offer customers a way to stay informed, chances are they’ll take their money elsewhere.
That’s why having a restock notification app like Back in Stock is essential for brands that want to maximize sales opportunities.
However, Back in Stock might not be the perfect fit for everyone. Whether it’s pricing, feature limitations, customer support concerns, or a desire for more customization, there are several reasons why merchants start looking for alternatives.
The good news? Back in Stock isn’t the only player in the game. Several other Shopify apps offer the same core functionality. Some even go above and beyond with additional tools and integrations. So, if you’re currently facing challenges with Back in Stock or just exploring your options, you’re in the right place.
Let’s dive in and explore some of the best Back in Stock alternatives available today.
Here’s our comprehensive comparison of each Back in Stock alternative, including user ratings and reviews. This detailed list of Back in Stock competitors in 2025 provides everything you need to make an informed decision.

Not to toot one's own horn, but STOQ is by far the best back-in-stock app in this list. It comes with all the features that are expected from a pre-order and back-in-stock alert app. Here are some of the key features you will get:

When selecting a Back in Stock app alternative, it’s important to look beyond just the "Notify Me" button. Start by evaluating how alerts are delivered via email, SMS, or both and whether the app allows full branding and template customization to match your store’s design.
Then, assess how well the app supports variant-level tracking (like size or color), as this can significantly improve accuracy and shopper satisfaction. Automation and integration are also important. Look for apps that work with your existing tools like Klaviyo, Omnisend, or Mailchimp.
If you serve global customers, ensure multi-language support is included. Robust analytics and reporting features help you understand product demand and make better restocking decisions.
Finally, review the app’s scalability and support, especially if you expect high traffic or need pre-order functionality. Consider your store size, volume of alerts, and whether the pricing fits your budget as your business grows.
If you've made it this far, we don’t even need to mention that STOQ is the most reliable, all-in-one “Back in Stock” alternative for Shopify brands.
