The short answer
ZoopCoder builds a custom Chrome extension on Manifest V3 for a fixed ₹9,999, with Chrome Web Store submission, in 7-10 working days. Chrome no longer accepts new Manifest V2 extensions, so V3 with a service worker is the only supported format. Google charges a one-time $5 developer registration fee, and store review usually takes from a few days to a few weeks.

- Content script to read or modify pages on specified sites

About this service
Chrome extensions are useful for small, sharp tools: scraping a listing into a sheet, adding buttons to a web app your team uses all day, blocking distractions, or giving your SaaS a browser companion. We build on Manifest V3, which Chrome now requires, with a service worker in the background, a popup for the interface and a content script for the pages it works on. The same build runs on Edge and Brave. We prepare the store listing and handle submission; Google reviews every extension, and requests for broad permissions take longer, so we keep permissions as narrow as the feature allows.
Questions before you buy
How long does Chrome Web Store review take?
Often a few days, sometimes a few weeks, especially when broad host permissions are requested. We keep permissions minimal to help.
Can I keep the extension private?
Yes, it can be published as unlisted, or installed privately for your team.
Will it work on Microsoft Edge?
Yes, Chromium browsers such as Edge and Brave run the same extension.
What if my idea is bigger than the fixed scope?
We quote larger extensions separately after reading the spec.
