I will build a custom chrome extension or migrate yours to manifest v3

I build Chrome extensions that do one job well, and I publish them myself. PowerBar for Xero and CookieMop are both live on the Chrome Web Store under my studio name, Danorie.

What I can build for you:

- A new Manifest V3 extension: popup, options page, content scripts, background service worker

- Moving an old Manifest V2 extension to V3 (the persistent background page is gone, so state and timers need a rewrite, not a patch)

- Connecting the extension to an API you already use (Shopify, Xero, FreshBooks, your own backend)

- Adding an AI step with Claude or OpenAI, with your key kept out of the page code

How it works:

1. Send me what the extension should do and which sites it runs on.

2. I reply with the permissions it will need and anything that could cause a store rejection.

3. You get the source code, a packed zip, and short notes on how to update it.

I keep permissions to the minimum the feature needs. Fewer permissions mean an easier review and fewer scary warnings for your users.

Not sure which package fits? Message me before ordering. I'd rather scope it first.
