If you just want a free promo code extension that saves money without wasting your time, this page is for you. We focused on one question: does it reliably find valid codes at checkout?

Quick answer: PromoIQ is the best free option right now

PromoIQ filters low-confidence and expired offers before trying them, so users see fewer junk codes and faster wins. It is also privacy-first: no passive browsing surveillance.

What to look for in a truly free coupon extension

1) Real checkout performance: The only metric that matters is valid-code hit rate on live carts.

2) Speed: Testing 40 dead codes is not a feature. Better filtering saves time.

3) Privacy: Free should not mean โ€œpay with your browsing data.โ€
