Chrome Extension Development
Custom browser extensions to automate workflows, enhance productivity, or provide unique user tools.
Betty and Selim build Chrome extensions from Brussels that feel like part of the browser, not something bolted on top of it. That covers everything from internal productivity tools your team uses daily to public products you ship through the Chrome Web Store. We build to Google's Manifest V3 standard, so your extension passes review, stays approved as Chrome changes, and keeps working long after launch.

Popup, side panel, inline overlay: whatever the interface, it feels native. We connect your extension to the services, databases, and login systems you already run, and we handle the whole Web Store submission ourselves, privacy policy, listing copy, and reviewer replies included. Chrome extension development at Studio XL starts from €2,500, which covers a focused extension with one clear job to do.
The final number depends on how many features you need, which systems we connect to, and whether the extension ships publicly through the Web Store or stays internal to your team. You'll know the budget before we touch a line of code.
What's Included
Built to Last, Approved by Google
We build to the latest Chrome standards, so your extension passes Web Store review, stays approved as Chrome evolves, and keeps working reliably long after launch.
Feels Like Part of the Browser
Popup, side panel, or inline overlay, your extension's interface is designed to feel native to the browser, never like something bolted on top of existing pages.
Connects to Any Service You Need
We connect your extension to external services, databases, and login systems, opening up workflows the browser can't handle on its own.
Chrome Web Store Submission Handled
We manage the full submission ourselves, privacy policy, store listing copy, reviewer responses, so your extension reaches users without unnecessary delay.
Case Studies
Our Process
Discovery
You send us your project, and Selim gets on a call with you to talk through your business and what the site needs to do. If it's a good fit, we lock in a start date.
Strategy + Design Direction
Betty maps out the structure and strategy, based on a short questionnaire and what you told us on the call. Selim turns that into a visual direction for your brand.
Creation
[OUR FAVORITE PART]Once the direction is signed off, Selim builds it: a website, an app, or whatever the project calls for. You'll see progress along the way, not just a reveal at the end.
Delivery
Once everything is approved, we hand over your files and set you up to run the site yourself. Then it's live, and it's yours.
Frequently asked questions
How much does a Chrome extension cost? +
Chrome extension development at Studio XL starts from €2,500. That covers a focused extension with one clear core function. The price depends on how many features you need, whether we connect to external services or databases, and whether you distribute publicly through the Chrome Web Store or internally. You get a clear quote before we start.
Will my extension pass the Chrome Web Store review? +
We build to Google's Manifest V3 standard, the requirement for new Web Store submissions, and we manage the entire review process for you: privacy policy setup, store listing copy, and replies to reviewer feedback. That's exactly the preparation that prevents the delays and rejections that catch out most extensions.
Can the extension connect to our internal systems? +
Yes. We connect extensions to external services, databases, and login systems, opening up workflows the browser can't offer on its own, like pulling data straight from your CRM into the pages your team already works in.
Is an extension only for public use, or also internal? +
Both. We build internal productivity tools you distribute privately within your organisation, and user-facing products published on the Chrome Web Store. Which route you take is one of the things that shapes the scope and the price.
