I will build a custom chrome extension for your business


About this gig
I build Chrome extensions and can take them all the way to the Chrome Web Store, including the parts most developers skip: Manifest V3 permissions, store listing copy, and localization for non-English markets.
My own extension is live on the Chrome Web Store, with a full web app behind it: Next.js, Supabase authentication and Stripe subscriptions, in English and Korean. You can see it at trybridgr.com. So I can build the extension on its own, or the whole product around it.
What I can build:
Content scripts that read or change web pages
Popups, side panels and options pages
Background service workers and API integrations
User accounts, payments and a web dashboard
Basic: a single-purpose extension, no backend
Standard: extension with a backend API and user accounts
Premium: extension plus web dashboard, auth, billing and Web Store submission
Message me before ordering with what you need the extension to do, and I'll tell you honestly what's realistic and which package fits.

FAQ
Will the extension be published under my name?
Yes. Extensions are published from your own Chrome Web Store developer account, so you own the listing. Google charges a one-time fee to register one. Publishing is included in Premium; on the other packages I will walk you through doing it yourself.
Will it work in Edge and Brave?
Yes. Manifest V3 extensions generally run in Chromium browsers such as Edge and Brave. Firefox needs some changes, so ask me first.
Do I get the source code?
Yes, the full source code comes with the delivery.
