Choosing a Shopify app: a 9-question checklist

The Shopify App Store has dozens of apps for almost every need. A poor choice can slow your store, leave code in your theme or surprise you with fees. Ask these questions before installing.

1. Do I really need an app?

Some needs are covered by your theme settings or by Shopify's built-in features. Every app is one more moving part to maintain.

2. Does it touch your theme code?

Modern apps work through App Blocks and App Embeds (theme app extensions). They're switched on and off in the theme editor and leave no code behind when removed. Avoid apps that inject code into your theme files.

3. Will it slow the store down?

Find out how much script the app loads on each page. Measure after installing — compare mobile results in PageSpeed Insights before and after.

4. Is it "Built for Shopify"?

This badge goes to apps that meet Shopify's criteria for performance, design and integration. It isn't everything, but it's a good signal.

5. Are the reviews recent?

Look at the last few months of reviews rather than the overall rating. Pay attention to support complaints and how the developer responds to negative reviews.

6. What language is support in, and how fast?

Being able to explain a problem in your own language saves real time. Check support channels and response times in advance.

7. How does pricing change as you grow?

Pricing tied to order count or revenue can bring unexpected costs as you grow. Read the trial length, plan limits and what happens when you go over them.

8. What data does it access?

Read the permissions requested during install. An announcement bar app doesn't need your customer data. Check the privacy policy and where data is stored.

9. What happens on uninstall?

A good app leaves no trace in your theme or store when removed. Read the documentation about any discounts, metafields or pages it creates.

One more tip

Trying a new app on a development store or a duplicate of your theme first keeps the risk away from your live store.
