Disclosure and short answer
We make Complimus, so read this as a vendor’s comparison. Every fact about the other apps comes from their own Shopify App Store listing or linked documentation, checked on 3 November 2026. Where a listing is silent we write “Listing does not say”, not “no”. All four apps show the lowest price of the last 30 days. What Complimus states on top: a daily price record per variant and per market, a rule you set per EU country, bulk fixes of wrong compare-at prices, EU hosting, and GPSR, the guarantee notice and the withdrawal button on every plan. What the others state that we do not: B2B catalogs (Omnibus Insight), 22 storefront languages, Shopify Flow triggers and a 30-day trial (Omnibus Owl), and lower paid plan prices (all three).

Complimus
Records every variant’s price every day, per market, and lets you set the rule per EU country, for example Poland’s reset at every price change. You choose which discount codes count, fix wrong compare-at prices in bulk and get email alerts on Business. GPSR, the guarantee notice and the withdrawal button are on every plan, including Free. Hosted in Germany, EU data only. Plans are on the pricing page.
How to choose
- If you need only the 30-day price and want the lowest bill, all three alternatives start below our Business plan.
- If you sell in several EU markets with different rules, ask each vendor how it handles Poland’s reset and per-market prices.
- If you also need GPSR, the guarantee notice and the withdrawal button, check which plan includes each.
- Ask every vendor the ten questions in our guide to choosing an Omnibus app, and get a worked example for a progressive discount.
