Specialist builds
Chrome and browser extension development
Browser extensions for productivity, monitoring and internal tools — built to survive Chrome's Manifest V3 rules and published to the Web Store.
- Starting from
- $1,500
- Chrome, with Web Store publishing included.
- Typical timeline
- 1–3 weeks
Extensions are small, but Chrome's Manifest V3 makes them tricky: background workers get suspended, timers stop, and storage has limits. Our own Random URL Reloader runs a separate reload schedule in every tab and keeps working when Chrome suspends its background worker.
We build extensions for teams and products — internal tools, companion extensions for a SaaS, and productivity tools — and handle Web Store publishing and review.
What you get
- Chrome extensions (Manifest V3)
- Firefox and Edge versions
- Companion extensions for your web app
- Sync with your backend or account system
- Chrome Web Store listing and review

Frequently asked questions
Do you handle the Chrome Web Store review?
Yes — the listing, permissions justification and review process, which is where many extensions get stuck.
Do I own the code?
Yes. You own the source code, designs and accounts from day one — repositories, app store listings and cloud projects are set up in your name, not ours.
