The Hidden 30% Off Mountain Duck Code

How I found a working Mountain Duck coupon (2025)

I started as a trial user ready to buy Mountain Duck but couldn’t find any discount code that worked. Even after emailing support, I was told promo codes were only available for Cyberduck license owners. After days of searching, I discovered a working 30% off Mountain Duck coupon through a verified coupon extension — and it still works as of November 2025.

I was on the final day of my Mountain Duck trial and ready to buy.

I emailed their support team asking for a small one-time discount, since the site only grants discounts to Cyberduck or competing-product owners.

After 11 days, I got a polite reply — but no promo codes available.

So I kept digging. Google showed nothing. Then I tested a coupon-finder Chrome extension, and out of around 12 expired codes, one actually worked — 30% off any bundle, from 1 to 50 users.

Verified on mountainduck.io/buy as of November 2025.

Still working as of Nov 2025 — may expire anytime.

Independently verified by a real user. No expired codes or spam — just tested deals that work.

How I Found It

I used a Chrome extension that scans and tests promo codes automatically. Most were dead, but this one slipped through. I’ll post verified working codes like this occasionally — no spam, no expired junk.

No spam — I'll only send verified deals.
