Dealophant vs Keepa
Keepa is a price history tool, usually run as a browser extension, for an Amazon product you already have open. Dealophant is a free website that ranks every listing in a category by price per unit before you pick one, and checks whether a deal is a real 90-day low. Keepa tells you if the listing you chose is at a good price for that listing. Dealophant tells you which listing to choose.
Quick verdict
If you are on a product page and want a detailed long-term chart, Keepa is the right tool. If you have not picked a listing yet and want to know which pack size or brand is cheapest per ounce or per unit, Dealophant is the right tool. Many careful shoppers use both: Dealophant to pick, Keepa to time the buy.
When Dealophant is the better fit
- You have not picked a listing yet and want the cheapest price per unit across brands and pack sizes.
- You want price per unit calculated for you, with no charts to read.
- You want a free website with no extension, no account and no paid tier.
- You want a quick yes or no on whether today's price is a 90-day low.
When Keepa is the better fit
- You already know the exact product and want multi-year price history.
- You want price-drop alerts on specific products at a target price.
- You are an Amazon seller or researcher who needs sales rank, offer counts or an API.
- You shop categories where timing matters more than pack size (electronics, tools).

FAQ
- Is Keepa free?
- Keepa has a free tier with price history charts and a limited number of tracked products. Full data, such as sales rank history and its API, needs a paid subscription. Dealophant is completely free with no paid tier.
- Is Dealophant a Keepa alternative?
- For shoppers, partly. Keepa charts the history of one product you already picked. Dealophant ranks every listing in a category by price per unit so you pick the right product first, and it checks prices against their 90-day low. Sellers who need Keepa's sales data should keep Keepa.
- Does Dealophant have price history charts like Keepa?
- Yes, for the last 90 days, at /price/ASIN for any product Dealophant tracks. Keepa keeps years of history. Dealophant's main job is the price-per-unit ranking across a category.
- Does Keepa show price per unit?
- No. Keepa tracks the price of each listing, not the price per ounce, roll or pod. Two pack sizes of the same product are separate listings in Keepa, so it cannot tell you which is cheaper per unit.

- No. Dealophant is a website. Search a category or paste an Amazon link at dealophant.com/check, with no extension and no account.
- Keepa or CamelCamelCamel: which is better?
