When extensions were last updated

A quarter have been abandoned for 2+ years

Figures cover the 292.5K live extensions we track in the Chrome Web Store (2.1B installs total). User counts are the store's own reported install numbers.

How big is the Chrome extension market?

The Chrome Web Store is the largest browser-extension market anywhere, and its installed base is enormous: the 292,000+ live extensions we track have 2.1 billion total installs between them. But that reach is wildly unequal. The median extension has just 9 users, and more than three-quarters sit under 100. Only 284 extensions have crossed 1 million users. For a founder deciding whether to build, the volume is not the hard part - the store already has hundreds of thousands of listings, and getting past a few dozen users is where almost everyone stalls. The stats above measure that reality: how many extensions there are, how big they actually get, and how they are rated.

Which categories are crowded, and which are open?

Extension count and audience size pull in opposite directions. Tools is by far the most crowded category with 79,000+ listings, yet the average Tools extension has only about 3,100 users - a lot of competition chasing thin reach. The best ratio sits elsewhere: Privacy has under 4,000 listings but averages ~44,000 users each, and Workflow averages ~29,000 users across its 36,000 listings. Communication, Accessibility, and Social also punch above their listing count. If you are picking a lane, reach-per-competitor matters more than raw size, and the category chart above shows exactly where the listings pile up.

Abandoned extensions are an opportunity

A quarter of the store is effectively stale. About 25.7% of live extensions have not shipped an update in two or more years, and 10% have gone untouched for five-plus years. Many still hold real user bases while their developers have moved on, so they no longer keep up with Chrome's Manifest V3 changes, new APIs, or user complaints. For a new builder, that is the clearest opening in the data: find a neglected extension with thousands of users and a pile of stale one-star reviews, and rebuild it properly. You inherit proven demand instead of guessing at it.

Chrome Extension Statistics FAQ

How many Chrome extensions are there?
We track 292,000+ live extensions in the Chrome Web Store. Together they hold about 2.1 billion installs, but the distribution is extremely top-heavy: only 1,771 extensions have more than 100,000 users and just 284 have passed 1 million.
How many users does the average Chrome extension get?
The median Chrome extension has only about 9 users, and more than 76% have fewer than 100. Roughly 9% ever reach 1,000 users and under 1% pass 100,000. A handful of breakout extensions hold most of the installs, while the typical listing stays tiny.
What is a good rating for a Chrome extension?
Among extensions that have any reviews the median rating is 5.0, and about 69% of rated extensions sit at 4.5 stars or higher, so the bar is high. But more than half of all live extensions have no rating at all, because most never get enough installs to collect reviews.
What are the least saturated Chrome extension categories?
By reach-per-competitor, Privacy (~44,000 average users across under 4,000 listings) and Workflow (~29,000 users across 36,000 listings) are the strongest. Tools is the most crowded category with 79,000+ listings but averages only ~3,100 users each, so it is the hardest place to stand out.
Is it worth building a Chrome extension in 2026?
It can be, but go in clear-eyed: the store is crowded and most extensions never clear 100 users. The best odds come from a specific niche or from rebuilding an abandoned extension - about 26% of live extensions have not been updated in two years, and many still have users waiting for a working alternative.
