What the Chrome Web Store actually looks like underneath
Most “extension niche” lists are guesswork. These numbers were read straight off Chrome Web Store listing pages: real install counts, the leader’s actual star rating, how many competitors rank for the term, and what share of them stopped shipping.

What extensions are allowed to reach
Grouped by the permission itself, so you can see who holds the keys.
Permission breakdowns
What each extension can actually reach, read from its own manifest. The store only shows a vague warning; these pages say what the permission lets it do.

WordPress plugins: still maintained?
An abandoned plugin is the most common way a WordPress site gets compromised. The directory shows a date; these pages show whether anyone still answers support threads.

How to read this
Rating is the leading extension’s own score, not an average across the category. That distinction matters: averaging pulls in abandoned listings with a handful of reviews and invents problems that are not there.
Stale is the share of ranked extensions whose last update is over twelve months old. A high number means incumbents stopped shipping, not that the category is unwanted.
A low leader rating paired with high install counts is the interesting combination — demand exists and the incumbent is disliked. A high leader rating with recent updates means the category is defended.
Source: Chrome Web Store listing pages, read 2026-09-16. Install counts are the store’s own rounded buckets. Categories with a leader under 10,000 installs or under 30 ratings are excluded as too noisy to interpret.
