Chrome Extension Ideas That Pay
Browser extensions are the most underrated opportunity in software. Lower competition than mobile apps, faster to build, and users who install extensions have high intent and willingness to pay.
Why Extensions Are Profitable
The Chrome Web Store has far fewer quality extensions than the App Store has apps. Competition is lower. Users who install extensions are power users, they customize their tools, which means they value software and will pay for it. Extension development is also simpler: HTML, CSS, and JavaScript. No app review delays.
