Hi everyone!
I’ve recently launched Sniffit - Product Finder & Price Checker and wanted to share it with the Firefox community.
The Problem:
Online shopping is full of overpriced resellers, “dropshippers,” and misleading social media ads. It’s often hard to know if you’re getting a fair price or just paying a 300% markup on a product available elsewhere.
How Sniffit helps:
Sniffit is a “quiet” assistant that works in the background. The moment you land on a product page, it analyzes the item and checks for cheaper versions or direct-from-manufacturer sources (like AliExpress or Amazon).
Key Features:
-
Instant Markup Alerts: Tells you if the item you’re looking at is being sold at a significantly higher price than elsewhere.
-
Visual Search: Finds visually similar products at fair prices with zero extra clicks.
-
Quiet & Lightweight: It doesn’t clutter your browser; it only appears when it finds a better deal.
-
Supported Platforms: Works on Shopify stores, fashion sites, and items found via Instagram/TikTok ads.
Proudly Optimized for Firefox Android 
One thing I’m particularly proud of is that Sniffit isn’t just for desktop. While mobile extensions are often overlooked or simplified, I’ve worked hard to ensure a full-featured experience on Android.
Shopping often happens on the go (scrolling through social media ads), so having the same “price sniffing” power in your pocket was a priority for me. If you’re a Firefox Android user, I’d love for you to give it a spin!
Why I’m sharing this here:
I built Sniffit to make online shopping more transparent. I’d love to get feedback from the Mozilla community on:
-
How accurate you find the price comparisons.
-
Any specific stores where you’d like to see better integration.
-
General UI/UX improvements.
