Before You Install Another Shopify App, Check These Things
A practical Shopify app checklist: how to evaluate a new app before installing it, audit your current app stack and remove apps safely without hurting speed or data.
Quick answer
Before installing another Shopify app, check whether an existing app or your theme already does the job, where the app loads (every page or only where needed), whether it uses theme app extensions that uninstall cleanly, whether a native Shopify feature covers it and which metric it should move. Audit your current apps quarterly: list each app's purpose, cost and storefront impact, remove what no longer earns its place and clean up leftover theme code.
Apps are the easiest thing to add and the hardest to remove
Every Shopify app that touches the storefront adds its own scripts, styles or widgets, and most stores never go back to remove the ones they stopped needing. Over time this quietly compounds into a slow storefront and a monthly bill nobody can fully explain.
Shopify's own guidance on theme performance stresses minimising JavaScript and third-party code, which is exactly what unmanaged app stacks add.
The pre-install checklist
Run through these before installing anything new:
- Does this duplicate something a current app, Shopify feature or your theme already does?
- Does it load on every page, or only on the pages where it is needed?
- Does it use theme app extensions, so it can be enabled per template and uninstalled cleanly?
- Is there a native Shopify feature or lighter alternative?
- Which metric should it move, and how will you know if it did?
- What happens to your data and theme if you remove it later?
- Is the app maintained, with recent updates and responsive support?
Want your app stack reviewed?
We audit Shopify stores for app bloat, leftover code and performance issues as part of our Shopify development services.
How to audit the apps you already have
List every installed app with its purpose, monthly cost, who asked for it and whether it touches the storefront. For storefront apps, note which templates it loads on. Then ask the owner of each app whether it is still used and what it achieved.
Group apps by job. Two review apps, two popup tools or overlapping upsell apps are common. Pick one per job and plan the migration of any data, such as reviews or subscribers, before removing the other.
| Keep | Review | Remove |
|---|---|---|
| Used weekly, clear metric, light footprint | Useful but heavy, or overlaps another app | Unused, duplicated, or no measurable value |
Removing apps safely
- Duplicate the live theme and test removal there first
- Export any data the app holds, such as reviews, subscribers or bundles
- Disable app embeds and blocks in the theme editor before uninstalling
- Uninstall, then search theme files for leftover snippets and scripts
- Re-test key journeys: product page, cart, checkout and account pages
- Measure speed before and after on the same templates
Make the review a routine
App audits work best as part of a regular routine rather than a one-off clean-up. Our Shopify maintenance checklist puts the review on a quarterly schedule, and the Shopify Core Web Vitals guide explains how to measure the speed impact. For choosing a first stack on a new store, see the apps worth installing when you're starting out.
Conclusion
Treat every app as a decision you will revisit. Check overlap, footprint and purpose before installing, audit regularly and remove apps carefully so speed and data stay intact.
Store slowing down after years of apps?

Common questions.
There is no fixed number. A store with many lightweight, well-built apps can be faster than one with a few heavy ones. What matters is what each app loads, where it loads and whether it still earns its cost.
