The most saturated Shopify app categories in 2026 (and the wide-open ones)
If you are deciding what Shopify app to build in 2026, the category you pick matters more than the code you write. We scraped the live Shopify App Store, 21,749 apps across 90 real categories, and the gap between the crowded categories and the quiet ones is enormous. A handful of categories hold more than 500 apps each. Sixteen hold fewer than 100. Picking the wrong side of that line means competing for attention you will probably never win.
What "saturated" actually means for an app builder
Saturation is not just how many apps share a category. A category can be busy and still winnable if the busy part is a long tail of dead apps nobody installs. What kills a new app is the opposite: a category where the top one or two apps own almost all the attention, so every search and every "related apps" carousel sends merchants to them, not you.
So I look at two numbers together:
- App count: how many live apps already carry that category tag.
- Review concentration: what share of the category's total reviews the single biggest app holds. Reviews are the closest public proxy we have for installs and attention. When one app holds 40% or more, the door is mostly shut.
A category is genuinely hard when both are high. A category is an opportunity when both are low and merchants still clearly need the thing.
The most saturated Shopify app categories in 2026
These are the categories with the most live apps. If you build here, you are entering a knife fight on day one.
| Category | Live apps | Median reviews per app |
|---|---|---|
| Analytics | 1,228 | 5 |
| Upsell and cross-sell | 932 | 11 |
| Shipping | 884 | 7 |
| Discounts | 875 | 10 |
| SEO | 836 | 8 |
| Chat | 768 | 5 |
The most crowded Shopify app categories

Notice the median review counts. In Analytics, with 1,228 apps competing, the median app has 5 reviews. That is not a healthy market with room for everyone. That is a thousand apps fighting over scraps while a few names take the installs. Building "another analytics dashboard" or "another upsell app" means starting at the back of a very long line.
Crowded is bad. Crowded plus first-party is worse.
App count alone can mislead you, so look at who sits at the top. Some of these categories are not just full, they are effectively closed because Shopify itself ships the default app.
- Workflow automation: 446 apps, but Shopify Flow holds 64% of all reviews in the category. Flow is free and built into the admin. You are not competing with other apps, you are competing with the platform.
- Chat: 768 apps, and Shopify Inbox holds 25% of the reviews. Merchants reach for the bundled option first.
When the category leader is a free, first-party Shopify app, treat that as a category to avoid unless you have a sharp, specific angle the native app cannot cover. A general "do it better" pitch does not beat free and pre-installed.
The other side: quiet categories with room
Now the opposite of a knife fight. A handful of categories have clear merchant demand, a much smaller field, and no single app owning all the attention. They share a tell: the apps that do exist tend to have higher median review counts than the crowded categories, which means the few apps there are actually getting used. There just are not many of them yet.
Take pre-orders. It has 95 apps against Analytics's 1,228, and its median app has 23 reviews against Analytics's 5. One twelfth the field, and each app gets more than four times the engagement. That is the shape of an opening: real demand, thin supply, beatable leaders.
The catch is that the genuinely open niches are almost never the ones you would guess. They are the unglamorous, specific corners nobody is excited to build, which is exactly why they stay open. You will not spot them browsing the App Store homepage, and any list of them printed here would be stale a month later. The real, current read is the part worth doing properly, per niche, right before you commit months to a build.
How to actually pick a category
A short, honest checklist before you commit months to building:
- Count the field. If the category already has 500-plus apps, you need a reason to believe you can stand out. Usually you cannot.
- Check who is on top. If a free first-party Shopify app or one giant holds most of the reviews, the door is shut. Move on.
- Confirm real demand. A near-empty category is only good if merchants actually want the thing. An empty category nobody searches for is empty for a reason.
- Look at engagement, not just count. A small category where existing apps each have decent review counts is a market with room. A small category where every app has 2 reviews is a dead one.
The categories worth your time sit in the middle: enough demand that merchants are searching and installing, few enough competitors that a good app can climb, and no platform-owned app sitting on the throne.
See the numbers for any category before you build
Eyeballing a category page only gets you so far. We built the MetricHQ Market Validator to do this read for you: type in a market and it pulls the live App Store data and tells you how crowded it is, how beatable the leaders are, whether the apps in it actually charge money, and roughly what it would cost in ads to compete. It is the same scraped dataset behind every number in this article.
Run it on the category you are tempted to build in, and on two or three quiet ones you had not considered. The open niches rarely look exciting at first glance, which is exactly why they are still there.
