I will develop a custom chrome extension for your business


About this gig
I build custom Chrome extensions that save time and add useful features to websites. Explain the result you want in plain language. No technical brief is required. You receive a working extension tested on the latest Chrome version, full source code, a simple installation guide, and revisions based on your package. I built Chainless Maps, a complete Chrome extension with a settings panel, seven languages, and a server-verified license system. It is currently in Chrome Web Store review. My process is simple: I confirm the scope, price, and deadline, then I build, test, and deliver the extension. Please message me before ordering if your project uses an external API, a third-party website, or Chrome Web Store publication. I do not build social-media bots, security bypasses, or tools that collect private personal data. The service is provided by a minor under an account owned by the parents of Mael and managed by them.

FAQ
Can you publish the extension on the Chrome Web Store?
I can prepare it for submission and guide you. Publication uses your own Chrome Web Store developer account, so you retain control.
What do you need to start?
A short description of the result you want, the website URL, and any example or screenshot. Plain words are enough.
What is included in the Basic package?
One clearly defined feature for one website. If your project needs more, I will recommend the right package before you order.
What projects do you refuse?
I do not build social-media bots, security bypasses, paywall or login circumvention, or tools that collect private personal data.
What if the target website changes later?
Extensions depend on the target website. A later website redesign may require an update. Defects within the agreed delivery scope are included.
