I will build a custom chrome extension, manifest v3 browser automation tool


About this gig
I build custom Chrome extensions (Manifest V3) for your website or workflow, written in JavaScript.
What I can build:
- Page modifiers that add, hide or change elements on sites you choose
- Popup and options-page UIs for settings
- Data helpers that capture or autofill information on pages you specify
- Background scripts, context menus, notifications and keyboard shortcuts
- Integrations with your own API or backend
How it works: send me a short spec of the features and the target sites. I confirm scope and timeline, build the extension, and deliver the source code with load-unpacked install instructions. The Premium package also includes help preparing your Chrome Web Store listing and publishing, plus a license key or payments integration.
I will be upfront if something is not feasible within Chrome's extension policies before you order.

FAQ
Which browsers do you support?
Chrome and other Chromium browsers such as Edge and Brave. Firefox or Safari ports can be discussed separately.
Do I get the source code?
Yes. Standard and Premium include the full source code; for Basic, message me before ordering and I can add it as an extra.
Can you publish it to the Chrome Web Store?
Premium includes help with your listing and publishing. You own the developer account; I guide you through submission.
Can you scrape or automate any website?
Only where it complies with the site's terms and Chrome Web Store policies. I will tell you upfront if a request is not feasible.
What do you need to start?
A short feature spec and the list of target sites or pages the extension should work on.
