Manifest V3 · Chrome Web Store

Chrome extension developer for custom browser tools

Small, focused extensions that add buttons, helpers, or workflows inside Chrome—scoped, documented, and ready for the Web Store when you need it.

Extensions suit teams that repeat the same steps in the browser, or products that need a lightweight companion to a web app. I build with Manifest V3 patterns, clear permissions, and update paths you can maintain.

Typical scope covers popup or side-panel UI, content scripts where needed, options pages, and packaging guidance for Chrome Web Store submission.

What’s included

Popup, side panel, or content-script behaviour scoped to your workflow
Options page and sensible permission requests
Build pipeline and store listing guidance
Integration with your existing site or API when required

Questions

What does a custom Chrome extension typically cost?

Scope drives price: a simple popup tool is a different job to a content-script workflow with API calls and an options page. The pricing guide lists typical bands; your brief determines where you land.

Store submission and review support can be included when scoped—I outline that in the quote.

Can you help get an extension on the Chrome Web Store?

Yes. I package Manifest V3 builds, document permissions clearly, and guide you through listing assets and developer account setup. You keep the store account in your name.

Can an extension connect to my existing website or API?

Often yes. Extensions can call your backend, open authenticated pages, or sync with a web app—permissions stay minimal and explained in the quote so reviewers and users understand why each is needed.
