Chrome extension usage statistics: how many users is normal

Chrome extension usage statistics answer a question every developer asks after launch: is my user count good? We read the public listings of 2,947 randomly sampled Chrome extensions in October 2026 to find out. The answer is humbling. The median Chrome extension has 13 users. Only 9.2% reach 1,000 users, 2.8% reach 10,000, and the top 1% of extensions account for about 80% of all users in the sample.

This post breaks the numbers down so you can place your own extension: user count percentiles, how the picture changes with the extension's age, how many extensions have ratings at each size, and what those numbers mean for how you track growth.

Key takeaways

• The median Chrome extension has 13 users. Three in four have fewer than 100.
• 9.2% of extensions have 1,000 users or more, 2.8% have 10,000 or more and 0.5% have 100,000 or more.
• Usage is extremely concentrated: the top 1% of extensions hold about 80% of all users in our sample, and the top 10% hold 98%.
• Age matters. Extensions first published in 2026 have a median of 7 users; those published before 2020 and still listed have a median of 1,000.
• Fewer than half of extensions (43.7%) have even one rating. Above 1,000 users, more than 93% do.

Where the data comes from#

The Chrome Web Store does not publish usage statistics for the store as a whole, so we built a sample. On October 22, 2026, the store's sitemap listed 383,061 items. We drew 4,000 of them at random and opened each public listing page; 2,947 were extensions (the rest were themes, legacy Chrome Apps or removed listings). Our companion post on how many Chrome extensions there are covers that count and the method in detail.

For each extension we recorded the user count shown on the listing, its rating and number of ratings, and the date it was first published. Three details about those user counts matter:

• The listing shows users, not installs or downloads. The figure tracks weekly users, which count browsers that have the extension installed and are running, not lifetime downloads. Our guide to why Chrome extension weekly users drop explains how Chrome counts them.
• Large numbers are rounded. Small extensions show exact counts such as "13 users", while larger ones show round figures such as 80,000 or 200,000.
• 12.1% of extensions show no user count at all. Most of them (86%) were first published in 2025 or 2026. We count them as zero, which is what they look like to a visitor.

With 2,947 extensions, the margin of error on the shares below is at most about 2 percentage points at 95% confidence. The sample is too small to measure the very top of the store precisely: it contained only one extension with more than a million users.

Chrome extension user count percentiles#

Here is where extensions sit when you line them up by user count:

The same data read the other way, as the share of extensions that reach each milestone:

So if your extension has 100 users, it is already in the top quarter of the store. At 1,000 users it is in roughly the top 9%, and at 10,000 in the top 3%. The estimated counts multiply the sample shares by the size of the store, so treat them as orders of magnitude rather than exact figures.

These results line up with earlier independent counts. DebugBear found a median of 17 installs in 2020, with 70% of extensions under 100 users, and 85% under 1,000 installs in 2024. In October 2026 the figures are a median of 13, 76.7% under 100 and 90.8% under 1,000. The long tail has grown longer, mostly because of the wave of new extensions published in 2026.

The top 1% of extensions hold most of the users#

Adding up the user counts in the sample shows how unevenly usage is spread:

Because a random sample rarely catches the handful of extensions with tens of millions of users, the real concentration is, if anything, higher than this. Extensions like Grammarly (41 million users on its listing in October 2026) and Google Translate (39 million) each have more users than the bottom 90% of the sample combined, scaled to the whole store.

For a developer, the practical lesson is that "average users per extension" is a meaningless benchmark. In our sample the mean was about 3,000 users while the median was 13. Always compare against percentiles, and preferably against extensions of a similar age and category.

How age changes the picture#

Half of today's extensions were first published in 2026, and they are still small. Grouping extensions by the year they were first published:

Two forces are at work. Older extensions have had more time to grow, and the old extensions that are still listed are survivors: the ones that failed, stopped working or never moved to Manifest V3 are gone. Both effects push the older medians up, so do not read the table as "extensions published in 2020 grew to 87 users". Read it as a benchmark for where an extension of a given age usually sits today.

Excluding everything published in 2026 gives a fairer view of established extensions: their median is 40 users, 62.6% have fewer than 100, and 17.1% have reached 1,000.

How many users is normal for a Chrome extension?#

Putting the tables together, here is a rough guide to where an extension stands:

If you want to place your own number precisely, this function interpolates between the percentiles above. It is a rough guide: use it to understand where you stand, not to set targets.

// Approximate share of Chrome extensions with fewer users than `users`
// (October 2026 sample of 2,947 extensions).
const BREAKPOINTS = [
  [0, 0], [4, 0.25], [13, 0.5], [84, 0.75], [833, 0.9],
  [3000, 0.95], [40000, 0.99], [100000, 0.995],
];

function chromeExtensionPercentile(users) {
  if (users >= 100000) return 0.995;
  for (let i = 1; i < BREAKPOINTS.length; i++) {
    const [x1, p1] = BREAKPOINTS[i];
    if (users <= x1) {
      const [x0, p0] = BREAKPOINTS[i - 1];
      const t = (Math.log1p(users) - Math.log1p(x0)) / (Math.log1p(x1) - Math.log1p(x0));
      return p0 + t * (p1 - p0);
    }
  }
}

console.log(`${(chromeExtensionPercentile(1500) * 100).toFixed(1)}%`); // "92.3%": ahead of about 92% of extensions

The interpolation uses a log scale because user counts are spread across six orders of magnitude; a straight line between 833 and 3,000 users would misplace most values in between.

Ratings follow users#

Ratings are where the long tail shows most clearly. Only 43.7% of extensions have at least one rating, and only 8.0% have ten or more. The share rises steeply with user count:

The last row rests on only 16 extensions, so treat it as indicative. The pattern is the useful part: below 1,000 users, a single review can swing your average, and many extensions have no rating for months. Among extensions with at least ten ratings, the median rating is 4.5 stars, and 77.2% are rated 4 stars or higher, which is why a 4.0 rating reads as below average to store visitors. Our guide to reading review and rating trends covers how to watch these numbers over time.

What Chrome extension usage statistics mean for tracking#

The distribution has a few direct consequences for how you measure an extension:

1. Benchmark against percentiles, not averages. An average of a few thousand users per extension says nothing about a typical extension. Use the percentile tables above, and compare against extensions of similar age.
2. Measure growth as a rate. Going from 40 to 80 users is the same 100% growth as going from 40,000 to 80,000, and both are meaningful at their stage. Our guide to Chrome extension user growth shows how to calculate weekly and monthly growth from the dashboard.
3. Watch the listing number and the dashboard together. The public number is rounded and lags the developer dashboard, so small changes show up in the dashboard first. The 10 Chrome extension metrics worth a weekly look puts both in one scorecard.
4. Track a peer group. Pick five extensions in your subcategory with similar age and size, and record their users and ratings daily. That tells you whether a flat week is your extension or the whole category.

Extenify does the last two for you. It records users, ratings, reviews and versions daily for your extension and any competitor, across the Chrome Web Store, Edge Add-ons and Firefox Add-ons, so you can see Chrome extension analytics for your peer group on one chart and get an alert when something changes.

Frequently asked questions#

How many users does the average Chrome extension have?#

The median Chrome extension had 13 users in October 2026. The mean was about 3,000, but that figure is pulled up by a small number of very large extensions and does not describe a typical one.

What percentage of Chrome extensions have more than 1,000 users?#

About 9.2% in our October 2026 sample, which is roughly 26,000 extensions. About 2.8% have 10,000 or more users and 0.5% have 100,000 or more.

Is 1,000 users good for a Chrome extension?#

Yes. 1,000 users puts an extension in roughly the top 10% of the Chrome Web Store, and in the top 6.4% of extensions first published in 2025.

How many people use Chrome extensions?#

Google does not publish the share of Chrome users who have an extension installed. The listing user counts cannot be added up to answer it either, because one person with five extensions appears in five counts, and one person with Chrome on two computers can count twice.

Why does my extension show no user count?#

12.1% of extensions in our sample showed no user count, and most of them were published in 2025 or 2026. A brand-new extension often shows no count until it has users, and Chrome can also hide the count on a listing when it detects suspicious activity.

Are Chrome Web Store user counts exact?#

Small counts are exact, while larger ones are rounded to figures such as 80,000 or 200,000. For exact numbers on your own extension, use the weekly users chart in the developer dashboard.

Summary#

Chrome extension usage statistics from a random sample of 2,947 listings in October 2026 show a store dominated by small extensions: the median has 13 users, three quarters have fewer than 100, and only 9.2% reach 1,000. Usage is concentrated in a few large extensions, with the top 1% holding about 80% of users. Age explains much of the spread, because half of today's extensions were published in 2026 and have a median of 7 users. Ratings follow the same curve, with most extensions under 100 users having none. Benchmark your extension against percentiles and against peers of the same age, measure growth as a rate, and track a small competitor group so you know what normal looks like in your own category.
