Custom browser extensions for Chrome, Firefox, and beyond.

BEST FOR:
  • Businesses that need a custom browser extension From simple productivity tools to complex integrations with your existing platform or API. We build extensions for Chrome, Firefox, or both.

BROWSER EXTENSION DEVELOPMENT
Specialist development for Chrome, Firefox, and the wider browser ecosystem.

Browser extensions are a genuinely useful way to extend your web application or give your users something directly in their browser. They are also more complex to build and maintain than most people expect. We develop custom browser extensions for Chrome and Firefox, handle CI/CD pipeline setup for teams that need automated deployments, and manage the full submission and publishing process to the Chrome Web Store and Firefox Add-ons platform. Building from scratch or picking up an extension you already have, we have the experience to do it properly.

WHAT BROWSER EXTENSIONS ARE GOOD FOR

Extending Your Web Application

Give your users functionality directly in their browser that would not be possible through a website alone. Tab management, page overlays, clipboard tools, and more.

Internal Productivity Tools

Custom extensions for your team that integrate with your internal systems, automate repetitive tasks, or surface information from your platform without switching tabs.

SaaS Product Integrations

If your product lives on the web, a browser extension can deepen the integration with your customers' existing workflows.

Content and Page Modification

Inject functionality, modify third party pages, or build tools that work across any website your users visit. Useful for accessibility tools, research platforms, and data capture workflows.

API and Backend Integrations

Extensions that talk to your existing API, authenticate users, and sync data in the background.

FREQUENTLY ASKED QUESTIONS
Do you build for Chrome and Firefox?
Yes. We develop extensions for both Chrome and Firefox. Where possible we build with cross-browser compatibility in mind from the start, so you are not maintaining two separate codebases.
Can you set up a CI/CD pipeline for our existing extension?
Yes. We set up automated build, test, and publishing pipelines for browser extension development teams. This covers everything from running tests on pull requests through to automated submission to the Chrome Web Store or Firefox Add-ons platform.
Do you handle submission to the Chrome Web Store and Firefox Add-ons?
Yes. We manage the full submission and publishing process, including writing store listings, preparing screenshots, and handling the review process.
Can you take over maintenance of an extension we already have?
Yes. We are happy to pick up existing extensions, review the codebase, and take over ongoing maintenance and updates. Get in touch with what you have and we will give you an honest assessment.
How long does a browser extension project take?
It depends entirely on the scope. Get in touch with your requirements and we will give you a realistic timeline.
Do you build extensions that integrate with our existing platform?
Yes. Most of the extensions we build connect to an existing API or backend. We handle the full stack, from the extension itself to any backend work required to support it.
