30.9K Chrome extensions are about to break
Google is deprecating Manifest V2. Tens of thousands of extensions with hundreds of millions of users will stop working — each one a gap in the market waiting to be filled. Forced churn like this is the clearest idea signal there is — proven demand, disappearing supply. ExtensionDB scores and ranks it across every marketplace.

FAQ
Questions before you buy
Short answers for developers, founders, and acquisition researchers deciding what software to build, rebuild or buy next.
What is included in ExtensionDB?
Every listing across Chrome, VS Code, WordPress, Firefox and Shopify — name, description, category, install or user counts, ratings, developer names and website links where public, update freshness, and (for browser extensions) manifest version and permissions.
Is this a subscription?
No. All-access is a one-time $29 payment and a single dataset is a one-time $9 payment — both include lifetime access and future updates.
Can I export the data?
Yes. Paid users can download each dataset they own as CSV, JSON or SQLite, so you can analyze it in spreadsheets, scripts, notebooks or your own database.
How does ExtensionDB help find ideas?
Every listing is a validated idea — someone built it and users adopted it. Search and filter to find stale-but-popular products, underserved categories, high-demand problems and Manifest V2 products that must be rebuilt.
How fresh is the data?
Datasets reflect store data through Jun 19, 2026 and are refreshed regularly. Your access includes future updates at no extra cost.
