We hand-pick your matches
A matching expert picks people by your stack, domain and time zone, and tells you why each one fits.
We handle the paperwork
We handle contracts, NDAs and invoices. You pay Lemon.io, and we pay your developer.
We stay after you hire

The lemon tea
A Chrome extension lives inside every page your users visit, so permissions and performance matter. Our developers build Manifest V3 extensions that pass Web Store review.
Minimal permissions
Candidates who ask for access to all sites by default fail. We pass developers who scope permissions and understand service workers.

Your channel, your developer
Your extension developer works in your team chat and tracker, without a go-between.

If you are looking to hire Chrome Extension developers, you can start with specialized developer communities like GitHub, where developers advertise their work by contributing to open-source projects. Next in line is LinkedIn, where you can directly connect with experienced professionals or freelance platforms if you are considering short-term or project-based employment. Yet, if you want to save time from detailed job descriptions, application screening, candidate interviews, and competency checking, consider Lemon.io. We can connect you with a pre-vetted Chrome Extensions developer within 48 hours.
Lemon.io gives you a chance to see how well a Chrome Extensions developer fits your team for as long as 20 hours of no-risk paid trial. If you like the results, you can either subscribe or hire them directly. If you are not satisfied, we’ll find another specialist to replace the previous one. Yet, such cases in Lemon.io are noticeably rare.
Yes, there is a huge demand for Chrome Extensions developers. This could be fuelled by the fact that Chrome is used as the most popular web browser, and hence, its extensions are pretty useful in enhancing productivity, customizing user experiences, and making integrations with other services. Specifically, Chrome Extensions are highly requested in domains like productivity tools, cybersecurity, ad-blocking, and e-commerce and social media browser-based applications. As businesses move toward the ease of integrated browser solutions, the demand for professional developers who can build and maintain such extensions only increases.
Lemon.io will match you with the best available Chrome Extension developers within 48 hours. We will set up a few calls between you and the candidates you’d like to meet face-to-face. We select only the most competent and trustworthy professionals for our platform. Each candidate has to go through a very serious selection process, which includes checking their profile, soft skills, and hard skills. Only 1% of all applicants are accepted to Lemon.io. Thus, you get the highest quality talent.
Lemon.io is a fast and cost-effective way to find contractors. We save you time by providing you with 1-2 pre-screened developer profiles in just two days. Our contractors undergo an in-depth screening process where we review profiles and assess soft and hard skills. Also, you can find flexibility with subscription or direct hire models, with a no-risk, paid 20-hour trial, work monitoring, and replacement if needed. Yet, replacements are quite uncommon at Lemon.io.
