01Quick answer
How much does it cost to build a Chrome extension?
It depends on what the extension does, how many screens it has and which services it connects to. A focused extension with one main job costs far less than a full product, so the first step is scoping a first version and agreeing a fixed quote.
02What you get

- Manifest V3 buildBuilt on the current extension platform with a service worker and modern APIs.
- Popup, side panel or page scriptsThe interface that fits the job, from a small popup to tools inside web pages.

Sukesh was great to work with. The website he built for me worked perfectly. He was quick to respond, even with the time difference. I highly recommend him. You will not disappointed.
Can you update my Manifest V2 extension to Manifest V3?
Yes. I rebuild the background logic as a service worker, update the APIs and permissions, and test it before resubmitting to the store.
Will you publish it to the Chrome Web Store?
Yes. I prepare the listing, screenshots and privacy details and handle the review. The developer account should be yours, so you own the listing.
Does it work in Edge and Brave?
Usually, yes. Extensions built for Chrome run in other Chromium browsers with little or no change, and I test in the ones you need.
Can the extension connect to our own systems?
Yes. It can call your API, CRM or database, with login and permissions handled safely.
Who owns the code?
You do. Once the project is paid, the code and the store listing are yours.
How long does a Chrome extension take?
A focused extension usually takes two to four weeks to build, plus the Chrome Web Store review, which often takes a few days.
What do I need to provide?
What the extension should do, the sites or tools it works with, API documentation if it connects to your systems, and a Chrome Web Store developer account in your name.
What happens after launch?
I fix anything that comes up and, if you want ongoing support, update the extension when Chrome changes its APIs or store policies.
