No revenue column, on purpose. Treat any extension revenue figure as a claim until sourced. Google's metrics page also notes the Users stat counts installations only.
The four traits they share
1. Tied to work. Writing, email, video messages, YouTube growth. Someone gets paid when the task goes well, which makes paying for the tool easy to justify.
2. Lives where the work happens. Grammarly sits in text boxes and Mailtrack sits inside Gmail, so nobody has to remember to open them.
3. A free plan that's truly useful. That's how they reached millions of users before asking for money.
4. A product beyond the extension. Most have web apps and team accounts. The extension is the front door of a bigger house. Is a Chrome extension a business tests this idea.

Scaling the pattern down
You won't start with 40M users. But the same four traits fit a tool for, say, recruiters cleaning up LinkedIn notes, or Shopify sellers checking listings.
In our crawl, 6,149 extensions sat between 10,000 and 99,999 users on 2 Oct 2026, which is plenty of room for that size of business. The top paid Chrome extensions page lists ten big examples.
- Pick a job tied to someone's income.
- Put the tool where they already work.
- Give away the core and charge for volume or teams.

Questions people ask
What is the highest-earning Chrome extension?
There's no public, verified ranking. Companies like Grammarly report on their business as a whole, not on the extension alone.
Can a small extension be very profitable?
It can, especially in a work niche with few rivals. Public proof is rare, so be wary of screenshots.
Do these extensions show prices in the store?
Mostly no. You'll find prices on their own pricing pages.
