Why MetaDesign Solutions
A Chrome extension development company built for
enterprise review and scale
Anyone can ship a popup. The hard parts are passing Chrome Web Store review, handling permissions correctly, and running the extension securely across a real user base. That is where we focus.

Our approach
How we build a Chrome extension
Predictable delivery, no black-box sprints. Each stage has a clear output.
01
Define
Requirements, a permissions audit, and a Chrome Web Store compliance review before a line of code.
02
Design
Popup, side panel, and content-script UX that follows Chrome's design and safety guidelines.
03
Build
Manifest V3 development: service workers, content scripts, and secure storage, in agile sprints.
04
Review
Web Store submission with written permission justifications and review-process management.
05
Publish and maintain
Versioned releases, staged rollouts, analytics, and ongoing platform-change support.
Customer value
Scope
Custom Chrome extension development services
Custom Chrome extension development
New extensions built on Manifest V3: popup, side panel, options page, content scripts, and a background service worker, designed around your business logic.
Manifest V2 to V3 migration
Rebuild legacy extensions on the current platform before they stop working. We port background pages to service workers and replace deprecated APIs.
Chrome Web Store publishing
Listing, screenshots, permission justifications, and review management, aimed at passing review on the first submission.
Enterprise extension deployment
Force-install across managed Chrome via group policy or MDM, with no user-side install step, for Chrome Enterprise fleets.
Backend and API integration
Secure connections to your CRM, SaaS APIs, and payment systems using OAuth2 and encrypted storage, without exposing keys to the client.
Maintenance and monitoring
Versioned releases, staged rollouts, analytics, and platform-change support so the extension keeps working as Chrome evolves.

Talent
Hire a Chrome extension developer, or a full team
You can hire a Chrome extension developer from MDS for a fixed-scope build, embed one in your team, or hand us the whole project. All three are Chrome-specialist engineers, not generalists assigned this week.
Hire a Chrome developerFixed-scope project
Total cost, timeline, and scope agreed upfront. Best for a defined build or launch.
Dedicated team
A ring-fenced squad (developer, QA, and a lead) managed by us and embedded in your workflow. Best for a product you will keep evolving.
Staff augmentation
Plug a senior Chrome developer into your existing team and tools. You set priorities, we deliver. Best for capacity gaps.
Pricing & Timelines
What does a Chrome extension cost?
A Chrome extension's cost depends on four things: the number of content-script targets, backend and API integration, permission and review complexity, and whether it ships to the public Web Store or across a managed enterprise fleet.
We give a fixed scope after a short discovery call rather than a headline price that would be wrong for your build.
What is fixed and known:
Store Registration
The Chrome Web Store developer registration fee is 5 USD, one time, covering up to 20 extensions. That is Google's fee, not ours.
Simple Popup Extension
A simple popup extension with minimal content scripts typically ships in about 2 to 3 weeks.
Complex Integration
A complex extension with robust content scripts and backend API integration typically ships in about 4 to 8 weeks.
FAQ
Asked first, every time.
Don't see yours here? Send us the question — a principal engineer will reply within 24 hours.
Yes. Every new extension is built on Manifest V3 with service workers and current APIs. Manifest V2 was removed from the Chrome Web Store on August 31, 2026, and we also migrate legacy V2 extensions to V3.
Yes. You can hire a Chrome extension developer for a fixed-scope build, embed one via staff augmentation, or engage a dedicated Chrome-specialist team.
Cost depends on content-script scope, backend integration, permission complexity, and whether you publish publicly or deploy to a managed fleet. We provide a fixed scope after a discovery call. Google's Chrome Web Store developer fee is a separate one-time 5 USD charge.
A simple popup extension is usually 2 to 3 weeks. A complex extension with content scripts and backend integration is usually 4 to 8 weeks.
Yes. You own the source code and the intellectual property from the first commit and receive the full repository on delivery.
Force-install via group policy or MDM for managed Chrome, with no user-side install step, suited to Chrome Enterprise fleets and internal tools.
Yes. We use OAuth2, JWT, encrypted credential storage, and CSP compliance, and we make backend calls without exposing API keys to the client.
Yes. Content scripts can inject UI, modify page content, and add functionality to any site, for use cases like price comparison, accessibility, productivity, and data capture, within Chrome's permission and data-use rules.
Chrome auto-updates published extensions for all users within about 24 hours. We use staged rollouts with feature flags and analytics to catch regressions before a full release.
Yes, if you want it. Edge runs on Chromium, so a Chrome extension can usually be adapted to Edge from the same codebase with minor changes. Chrome remains the primary target.
Chrome holds roughly two-thirds of global browser usage, so building for Chrome reaches the largest audience with a single platform, and its extension APIs and enterprise deployment tooling are the most mature.
