Chrome extension development

Put your tool exactly where users already work: inside the browser, on top of the websites they use every day.

What is a browser extension?

A browser extension is a small program that adds features to a web browser such as Chrome or Edge. Extensions can modify web pages, capture data, add sidebars and AI assistants, and connect browsers to other systems.

What our browser extension development covers

Chrome and Edge extensions that add tools to the browser your team already uses.

Productivity tools

Shortcuts and automations in the browser.

AI sidebars

Assistants that read the current page.

Data capture

Save leads and data to your CRM.

SEO tools

On page analysis and audits.

Manifest V3

Current Chrome standards.

Store publishing

Listing and review handled.

How we approach browser extension development

Extensions are fast to build and distribute, making them ideal for focused tools.

Chrome Web Store policies are strict on permissions; we request only what is needed.

Every project starts with a short discovery call and ends with software you own: source code, data, cloud accounts and documentation are handed over in your name.

From first call to launch

The same five stages for every build, with a working demo at the end of each sprint so you see progress, not promises.

  1. Discovery

    We map your process, users and data, agree the first release and give you a fixed price for it.

  2. Design

    Clickable prototypes of the key screens, reviewed with the people who will use them every day.

  3. Build in sprints

    Two week sprints with a demo each time. You can change priorities between sprints.

  4. Test and launch

    Functional, security and load testing, data migration, training and a planned go live.

  5. Support and grow

    Monitoring, fixes and new features on a monthly plan, or a clean handover to your team.
