HIRE DEVELOPERS / CHROME EXTENSION DEVELOPERS
Most Chrome extensions get built once and slowly break — a permissions change here, a service worker timeout there, a Manifest V3 requirement nobody planned for. We build extensions for enterprise clients and consumer products that keep working past launch, not just past the demo.
Background service workers, content scripts, popup UIs, options pages, cross-origin messaging — the full architecture, not just the popup. Manifest V3 by default, Web Store submission handled end to end, built to pass Google's policy review the first time.
Manifest V3 architecture, service worker lifecycle, content script injection, Chrome APIs — every developer we vet gets tested on all of it, plus a track record of extensions that actually cleared Web Store review.
A short match process gets a developer embedded in days — the rest of the six-week hiring cycle just doesn't happen here.
A full product extension needs full-time. Ongoing Chrome updates need part-time. A Web Store rejection or an MV3 migration needs a few billed hours. Whichever one it is, that's the model.

Manifest V3 migration, service worker limits, cross-origin restrictions, CSP, Web Store rejection — extension development gets hard exactly where most teams haven't looked yet. Ours have already been through all of it on real, published extensions.
One Chrome extension developer, full-time, owning everything from architecture to Web Store submission inside your standups. Right for a team where the extension is the product, not a side feature.
Contact us for pricingTwenty hours a week, sized for a published extension that needs Chrome version updates, maintenance, and the occasional new feature — not a full-time seat.
Contact us for pricingWeb Store rejection, an MV3 migration, a service worker bug, a content script question — billed by the hour, for exactly the problem in front of you.
Contact us for pricingMatch this to how your team already builds extensions, or tell us and we'll pick.
MV3 architecture, build, testing, Web Store submission — all ours to run. You review progress and steer what features come next.
You've already got the product. What's missing is a Chrome extension developer who slots straight into your existing workflow to build or maintain it.
Backend APIs and product calls stay with your team. Service workers, content scripts, permissions, and store review become ours.
Strong web and systems engineering backgrounds, not just JavaScript hobbyists — here's what actually goes into a secure, maintainable extension.
Core APIs for tabs, storage, scripting, and the extension lifecycle itself.
The current manifest standard: service workers, declarativeNetRequest, and the permission model Google now requires.
The cross-browser standard behind extensions that run on Chrome, Firefox, and Edge alike.
Firefox packaging and review, for teams distributing beyond Chrome.
Microsoft Edge publishing through Partner Center, riding on the same Chromium compatibility.
