Chrome extensions · Custom tools

Browser tools built around one specific job.

When off-the-shelf software adds too much complexity or still misses the workflow, a focused Chrome extension or web utility can be the better answer.

Small software can make a large operational difference.

I design and build extensions that remove repetitive browser work, bring useful information together or make an interaction faster. The scope covers the user flow, Chrome APIs, permissions, privacy, error handling, testing and release.

  • Workflow extensions

    Automate repetitive actions and make browser-based work faster and more consistent.

  • Content and page tools

    Work with permitted page content, selections, links or structured information.

  • Internal utilities

    Focused tools for a team when public software does not match the process.

  • Product development

    Shape the idea, test usability, prepare store assets and support releases.

How it runs

  1. 1

    Define the job

    Describe the repeated task, the users, the environment and the result you want.

  2. 2

    Prototype

    Validate the interaction before investing in the full extension.

  3. 3

    Build and test

    Implement permissions, states, errors and browser behaviour.

  4. 4

    Release

    Prepare the package, documentation and Chrome Web Store materials.

Grabbit grew to 150,000 installs before it was sold: first-hand experience of extension development, QA, support and growth.

Questions before we begin

Can you build an extension for internal company use?

Yes. It can be distributed privately, according to your organisation’s Chrome environment and requirements.

Do you publish it to the Chrome Web Store?

I prepare the package and listing materials and support the submission. You should own the publisher account.

Can an extension work with any website?

Only with the required permissions and within browser and website limits. Feasibility and privacy are reviewed before development.

Can you improve an existing extension?

Yes, including Manifest V3 migration, debugging, usability changes, performance and new features.
