Hey, it's Michael
I've shipped multiple Chrome extensions from scratch.
Along the way, I wasted weeks on the same problems every time. Wiring up payments, fighting Google OAuth, getting rejected by the Chrome Web Store.
So I built the starter kit I wish I had.
ExtensionFast gives you everything you need to go from idea to a published, monetized extension. No need to repeat my mistakes.
If you've been sitting on an extension idea, is your shortcut to getting it live and earning.
One price. Everything you need to ship and get paid.
Love it or your money back, 30-day guarantee.
