Gluten-Free Scanner: Scan Any Barcode to Check Gluten & Celiac Safety

If you live with celiac disease or eat gluten-free, every shopping trip means turning packages over and reading fine print. Gluten hides in obvious places like bread and pasta, but also in sauces, seasonings, malt flavouring, and some processed meats — and a recipe can change without the front of the package changing at all.

SkanSure’s gluten-free scanner works right in your browser, with no app to install. Point your camera at a barcode (or type the number in), and SkanSure pulls up the product record from Open Food Facts, the open crowdsourced food database, then checks two things: the product’s declared allergen information, and its full ingredient list, screened against known gluten sources — wheat, barley, rye, oats that aren’t certified gluten-free, malt, and the less obvious ingredient names gluten hides behind.

You get one of three plain answers. Gluten-Free means the product carries a gluten-free label or has a complete ingredient list with no gluten found. Contains Gluten means a gluten allergen is declared or a gluten ingredient was found, and the result names it. Unknown — check the label means the data is too thin or contradictory to decide. If a record mentions possible traces (“may contain”), the result is never shown as simply gluten-free — traces always downgrade it.

That “Unknown” answer is deliberate. Product data is crowdsourced and can be incomplete or out of date, so when the record isn’t good enough, SkanSure says so instead of guessing — a wrong “safe” is the worst result a scanner can give someone with celiac disease. Every result names its source and shows when the record was last updated, and the exact rules are written out on our methodology page.
