You will get a Chrome extension | Manifest V3, browser extension, Web Store ready
Project details
A browser extension puts your tool one click away - inside the browser your team and customers already use. But extensions have rules of their own: Manifest V3, store review policies, permissions that must be justified. Get them wrong and Chrome rejects it.
We are MiKiTech, a registered software company (not a solo freelancer). We build Chrome extensions that pass Web Store review: popups, content scripts, options pages, API and backend integrations. We also revive old Manifest V2 extensions that Google switched off.
How to pick your tier:
• One core feature: a popup tool or page tweak - Starter
• Up to 3 features with options page + API integration - Standard
• Full product + Web Store submission help + Edge/Firefox version - Advanced
Why new clients pick us:
• Full source code and install guide at EVERY tier - no paid unlock
• Built on Manifest V3, written to pass store review
• Launch pricing while we build our Upwork track record - same senior team
• 100% async, no meetings - replies under 12h (GMT+7)
Message us with what your extension should do - we reply with an honest scope and a fixed price.
