Looking to hire Chrome extension developers who understand Manifest V3 and not just the old way of doing things? Our extension engineers build content scripts, service workers, and polished popup UIs that work across pages, survive the migration to MV3, and pass Chrome Web Store review on the first submission.
Browser extensions look simple until you hit the real constraints: service workers that go idle, content scripts that need to talk to the page without breaking it, permission warnings that scare users away, and a review process that rejects anything overreaching. Our developers know how to architect message passing, scope permissions tightly, and handle cross-origin requests cleanly so your extension is both approved and trusted.
Whether you need a productivity tool, a data capture extension, a SaaS companion, or a cross-browser build for Chrome, Edge, and Firefox, we offer flexible engagement models to match your scope and budget.

Why Hire Through Us
Benefits of hiring developers through Hevcode
Pre-Vetted Extension Experts
Every developer is tested on Manifest V3 internals and has published extensions that passed Chrome Web Store review, not just local prototypes.
Quick Onboarding
Start working with your extension developer within 48 hours. Share your idea or existing extension and build begins fast.
Flexible Engagement
Hire hourly to fix a rejected submission or full-time to build and maintain a feature-rich extension. Scale to match your roadmap.
Direct Communication
Work directly with the developer building your extension. No middle layer between you and the person handling permissions and review.
Timezone Overlap
We ensure 4+ hours of overlap with your timezone so review feedback and browser update breakages get addressed in real time.

Frequently Asked Questions
Common questions about hiring developers
What is the experience level of your Chrome extension developers?
Our extension developers have 3-8+ years of JavaScript and TypeScript experience and have published multiple extensions to the Chrome Web Store. They are fluent in Manifest V3, content scripts, service workers, message passing, and the review policies that get extensions approved.
How quickly can an extension developer start on my project?
We can have a developer onboarded within 48 hours of selection. Once you share the spec or your existing extension, work can often begin the same day. For urgent fixes we can expedite to 24 hours.
What if the developer or extension isn't a good fit?
We offer a 1-week risk-free trial. You see a working build first. If the extension does not behave as needed or the developer is not the right fit, we replace them at no cost or provide a full refund.
Do your developers work in my timezone?
We ensure a minimum 4-hour overlap with your working hours. This matters because Web Store review feedback and Chrome updates can break an extension at any time, and you want it handled live rather than the next day.
How do you ensure quality and Web Store approval?
Our developers scope permissions to only what is needed, justify every host permission, isolate content script styles, write clean message passing, and test across builds. They prepare the submission to match Chrome Web Store policy so it passes review the first time.
Can you migrate my old extension or build for multiple browsers?
Yes. We handle Manifest V2 to V3 migrations and can build cross-browser extensions for Chrome, Edge, and Firefox from a shared codebase. We can also scale into a full team with design and QA for larger extensions.
