Browser extensions

Custom browser extensions for Chrome, Edge and Firefox

Your team works in the browser all day. A small extension built around your workflow can remove hundreds of repetitive clicks, bring data into one place and help close deals faster.

  • Built on the latest Manifest V3
  • Runs on Chrome, Edge, Firefox
  • Chrome Web Store publishing support

A small tool in the browser that saves time every day

A lot of office work is still copying information from one page to another: grabbing customer details from a marketplace, pasting them into a spreadsheet, checking prices, adding notes and reporting. These small actions add up to many working hours and plenty of mistakes.

We build extensions that run right inside the browser your team already uses. An extension can read and fill in data on web pages, show a side panel with useful information and connect to your management software or CRM. Install it internally for your team, or publish it on the Chrome Web Store for your customers.

What we build

Types of extensions we build

From internal tools for your team to products published for everyday users.

  • Chrome, Edge and Firefox extensions

    One codebase for the major browsers, with a clean, easy-to-use popup and side panel.

  • Sales and customer service assistants

    Save customer details, quick reply templates, price comparisons and order notes on the page you are viewing.

  • Web workflow automation

    Auto-fill forms, collect permitted data and export lists to Excel — less manual copy and paste.

  • Internal system and CRM integration

    Sync data from the browser to your management software, CRM or Google Sheets through secure APIs.

  • WordPress and Shopify plugins

    Add custom features to websites running on WordPress, WooCommerce or Shopify.

  • Chrome Web Store publishing

    We prepare descriptions, images and the privacy policy, and handle review submission until release.

FAQ

Frequently asked questions

Which browsers will the extension run on?

Extensions built on the common standard run on Chrome, Microsoft Edge, Brave, Opera and other Chromium browsers, and can be packaged for Firefox as well. Safari requires a separate package; we will advise you if you need it.

Do I have to publish the extension on the Chrome Web Store?

No. Internal extensions can be installed directly or published as unlisted. If you want to serve customers, we prepare the listing and submit it for review on the Chrome Web Store and Microsoft Edge Add-ons.

Is the extension safe for my data?

We only request the permissions that are truly needed, limit the extension to the agreed websites and never send data outside your systems. You receive the source code to review.

What is Manifest V3 and does it matter?

Manifest V3 is the current required standard for Chrome extensions, safer and lighter than the old one. Every extension we build follows it, so you do not need to worry about it being phased out.
