About this gig
Need a Chrome extension that actually works the way you need it to?
I build custom Chrome extensions using Manifest V3 clean, functional, and ready to use. I've built STOFUS, a fully working productivity extension with scheduled website blocking, keyword filtering, timed blocks, and a friction page system. That's the standard I deliver.

FAQ
What kind of Chrome extensions do you build?
I build frontend-focused Chrome extensions using Manifest V3, including productivity tools, utility extensions, popup interfaces, options pages, content scripts, website enhancements, and custom browser features.
Can you modify or fix an existing Chrome extension?
Yes, I can add features, fix bugs, and improve the UI of existing extensions.
Do you develop backend features or authentication systems?
No. This gig focuses on frontend Chrome extension development. Backend APIs, databases, Firebase, Supabase, Google authentication, payment systems, and other server-side integrations are outside the scope of this service.
Will I receive the source code?
Yes. All packages include clean source code with the final delivery.
Can you publish my extension to the Chrome Web Store?
I can assist with Chrome Web Store submission if your package includes publishing and you already have a Chrome Developer account. Approval is ultimately handled by Google and cannot be guaranteed.
What do you need before starting?
Please provide a clear description of the extension, the features you need, reference examples (if any), wireframes or designs (optional), and any branding assets such as icons or logos.
Should I contact you before placing an order?
Yes. If your project has multiple features or you're unsure which package fits your requirements, please message me first so we can confirm the scope before the order begins.
