What we build

Chrome extension services

Productivity & Workflow Extensions

Extensions that streamline daily workflows — tab management, keyboard shortcuts, custom dashboards, and one-click actions that save your team hours every week.

  • Custom popup UI with React & Tailwind CSS
  • Chrome Storage API for persistent settings
  • Keyboard shortcut & context menu integration
  • Cross-device sync via chrome.storage.sync
Data Capture & Scraping Extensions

In-browser scrapers and data capture tools that extract page content, form data, or DOM elements directly into your database or spreadsheet.

  • Content scripts for DOM access & extraction
  • Page action triggers on specific URLs
  • Background service worker for async jobs
  • REST API / Airtable / Google Sheets export
UI Injection & Content Overlay

Overlay custom UI onto any website — sidebar panels, floating widgets, annotation tools, and interactive overlays injected seamlessly into third-party pages.

  • Shadow DOM injection for style isolation
  • React portals rendered inside target pages
  • MutationObserver for dynamic page support
  • Custom floating panels & sidebar drawers
Secure API-Connected Extensions

Extensions that authenticate users via OAuth2, connect to your backend APIs, and handle sensitive data securely — built to pass Chrome Web Store review.

  • OAuth2 / Google Sign-In via chrome.identity
  • Secure token storage (not localStorage)
  • Background fetch with retry & error handling
  • Chrome Web Store submission & publishing

How we work

Our process

01

Scope

Define permissions, target URLs, user flows, and API dependencies. We review Chrome Web Store policy compliance upfront.

02

Design

Wireframe popup, options, and injected UI. Align on UX before a line of code is written.

03

Build

Develop using Manifest V3 best practices — minimal permissions, secure storage, and service-worker architecture.

04

Publish

Package, test across Chrome profiles, and guide you through Web Store submission with assets and descriptions.
