Extensions built for Manifest V3

The Chrome Web Store now only accepts Manifest V3 extensions, which changed how they work under the hood. Background pages became service workers that shut down when idle, remote code is banned, and network blocking moved to declarative rules. Many older extensions and tutorials still assume V2, which is why a fair share of extension jobs are really migrations. The agent builds to V3 from the start.

Permissions get the same care. Broad permissions trigger install warnings and draw extra scrutiny during Chrome Web Store review, so the agent requests the narrowest set that does the job — specific host permissions instead of all sites, activeTab where that's enough, optional permissions requested only when a feature needs them. Fewer warnings tend to mean more installs and a smoother review.

Publishing happens under your own Chrome Web Store developer account, so the listing and its users belong to you. The agent prepares everything the store asks for: the zipped package, icons, screenshots, a store description, the privacy practices answers and a privacy policy if the extension handles user data. You click submit; if the store sends feedback, fixing it is covered by your revision rounds.

What you receive

  • Full source code and a store-ready .zip package
  • Icons, screenshots and a written Chrome Web Store listing
  • Privacy practices answers and a simple privacy policy draft
  • A permissions list explaining why each one is needed
  • Two revision rounds, including fixes requested by store review

When to hire a person instead

Extensions that scrape sites against their terms, inject ads, or read browsing data users haven't knowingly agreed to share are not jobs we'll take. Firefox and Safari versions are possible but quoted separately, since Safari needs an Xcode wrapper and an Apple developer account.

Hire a Chrome extension developer: common questions

How much does a Chrome extension cost to build?
Fixing an existing extension starts at $99. A simple single-purpose extension is about $149 to $249, and a Manifest V3 migration or a side-panel tool connected to your API typically costs $399 to $499. Extensions with user accounts and a backend start around $999. The fixed price appears in the proposal before you pay.
Who publishes the extension to the Chrome Web Store?
You do, from your own developer account, which needs a one-time $5 registration fee paid to Google. That keeps ownership of the listing and its users with you. We prepare the package and every listing asset, walk you through the submission form, and fix issues the review team raises using your revision rounds.
How long does Chrome Web Store review take?
It varies. Simple extensions with narrow permissions are often reviewed within a few days, while those requesting broad host access or sensitive permissions can take longer. Review time isn't in our control, so delivery dates in the proposal cover building and packaging, not Google's approval.
Can the extension work on Edge, Brave or Firefox too?
Edge, Brave, Opera and other Chromium browsers run Chrome extensions with little or no change, and Edge has its own add-ons store you can submit to. Firefox supports most of the same APIs but usually needs small adjustments and a separate listing. Tell us which browsers matter so the proposal covers them.
Will my extension collect user data?
Only what you ask it to, and the store requires you to disclose it. The agent keeps data on the user's device with Chrome's storage API by default, sends nothing to a server unless a feature needs it, and drafts accurate answers for the store's privacy practices form so the listing isn't rejected.
