Most crackers on the “keto” shelf are fine on fat and protein but quietly heavy on starch. We pulled the current panels and kept only products whose nutrition numbers are all sourced. We rank by ketoside net carbs, never by price, and where we haven’t checked a price yet we say so, and the list will grow as we verify more labels.
Net carbs here = total carbohydrate minus fiber, minus allulose and erythritol in full, minus half of other sugar alcohols such as maltitol. Glycerin is not subtracted. “Net carbs” isn’t a term the FDA defines, and the American Diabetes Association recommends counting total carbs, so we show both. How we calculate net carbs.

None of these lists sugar alcohols, so ketoside net carbs here = total carbs minus fiber.
Not keto-friendly despite the marketing: Simple Mills Almond Flour Crackers (Fine Ground Sea Salt) come to 16 g net carbs per 17 crackers (18 g total carbs, 2 g fiber). Tapioca and cassava are the main carbs. [5]
Cheese crisps vs seed crackers vs almond-flour crackers
- Almond-flour crackers: HighKey Cheddar is 6 g total carbs and 2 g fiber per about 12 pieces (28 g), so 4 g net. [4]
- Cheese crisps are just baked cheese, so they’re the lowest in carbs in our table. Whisps Parmesan shows 0 g total carbs per 28 g on the current 2.12 oz bag; the brand page and an older 1 oz label say 1 g, and since US labels may show less than 0.5 g as 0 (21 CFR 101.9), both can be right. [1] ParmCrisps Original (Parmesan only) is 1 g total carbs and 13 g protein per 19 crisps (28 g), with 370 mg sodium, per the brand’s Original panel. [3]
- Seed crackers: Flackers Sea Salt is flaxseed-based: 10 g total carbs, 9 g fiber, 1 g net per 8 crackers. [2]
Low carb pretzels
We haven’t verified a low carb pretzel panel from a US source yet, so none are ranked.

HighKey Gluten Free Cheddar Almond Flour Crackers are the cheddar-cracker swap in our data: 6 g total carbs, 2 g fiber, 4 g ketoside net carbs and 7 g protein per about 12 pieces (28 g); the label also claims 4 g net. [4]

How we check
Each product record links to the nutrition panel we used (retailer or brand page), with the store and price where we checked one, and the date we checked it. We only list products whose required fields are all sourced; anything else stays off the tables until it is. Where sources conflict, we say which one we used. We haven’t taken our own label photos yet; that waits on a US tester. We re-check labels at least every 28 days.
