About Dupie
Stop overpaying for the same ingredients.
Scan a beauty product — or just type its name — and Dupie shows you cheaper alternatives with a similar ingredient composition. Every suggestion comes with a number you can check, not a vibe.
HOW IT WORKS
1. Scan or search
Point your camera at the barcode. No barcode on the box? Search by name — it covers the whole catalogue, not just scannable products.
2. See the match
We compare the published ingredient lists (INCI) and score how close the two formulas really are — shared actives, the base formula by label order, and overall overlap.
3. Save the difference
See the price range across shops, the price per 100 ml, and exactly which ingredients the two products share and where they differ.
WHERE THE NUMBER COMES FROM
A match score is a claim about someone's product, so we only show one when we can back it up — and we always say which kind it is:
• Our calculation — we hold the full ingredient list for both products.
• Published by a source — an independent ingredient database compared them. We show their number and label it as theirs.
• No number, words instead — for makeup the shade decides and for fragrance the scent does, and neither can be read from an ingredient list. There we show agreement between independent sources instead.
We never invent a percentage to fill a gap.
WHAT'S INSIDE
• 22,000+ products with cheaper alternatives
• 92,000+ alternative suggestions
• 97,000+ products searchable by name
• 104,000+ barcodes recognised
• Ingredient-level comparison: what both share, what only one has
• Price ranges from real shop listings — never an invented price
• Your shelf: keep the dupes you liked
• Watchlist: we'll tell you when something you scanned finally gets a dupe
• 70 languages, right-to-left included
HONEST BY DESIGN
Dupie compares publicly available ingredient lists. A high match means the compositions are similar — not that two products are the same, and not that they will feel or perform identically on your skin. Where we don't have the data, we say so instead of guessing.
No account needed. Scan your first product straight away.
