The short version

  • Only Algopix has a free tier, so it costs nothing to try first.
  • Each has a real cost: Algopix the demand and competition figures are modelled estimates built from sampled marketplace data rather than numbers the marketplace reports, so they rank candidates usefully but should never be treated as a forecast for one product you are about to buy in quantity.; Mollie non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • They diverge on capability: Algopix covers Multi-marketplace comparison, Mollie covers Local payment methods.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Algopix

  • The demand and competition figures are modelled estimates built from sampled marketplace data rather than numbers the marketplace reports, so they rank candidates usefully but should never be treated as a forecast for one product you are about to buy in quantity.
  • Profitability calculations depend on a stored marketplace fee schedule, and marketplaces revise referral and fulfilment fees regularly, so a margin figure computed against a stale schedule can be optimistic in exactly the categories where margin is thinnest.
  • Marketplace coverage depends on API access that the marketplaces control, so the set of sites and regions a tool like this supports can narrow without notice and the comparison you subscribed for may not be the one you get in a year.
  • It says nothing about supply, so a product that screens as profitable can still be unsourceable, subject to a minimum order you cannot meet, or restricted on the marketplace to approved sellers only, and none of that appears in the analysis.
  • It is a subscription that produces no asset, so unlike a listing tool or a storefront there is nothing left when you cancel, and the ongoing cost has to be justified against the incremental margin of decisions you would otherwise have made by hand.

Mollie

  • Non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • Coverage is built around European methods, so if you expand into Latin America or Southeast Asia you will need a second processor and a second reconciliation process rather than extending Mollie.
  • The in-person Pro plan requires a one-year contract and charges 20 pounds a month per additional terminal, so a shop with four tills pays 80 pounds a month in terminal fees before any transaction cost.
  • Mollie offers no interchange-plus option publicly, so large merchants cannot see or benefit from falling interchange the way they could on a cost-plus contract with an acquirer.
  • The developer tooling and reporting are lighter than the largest processors, so finance teams that want detailed fee breakdowns or granular reconciliation exports often end up building that layer themselves.

Answered from the vendors’ own pages

Algopix: Is this a selling platform?

No. It informs the decision about what to sell. Listing, order management and fulfilment all happen elsewhere.

Mollie: Does Mollie charge a monthly fee?

Not on the online payments plan. You pay only per successful transaction. In-person Pro is 20 pounds a month.

Algopix: How accurate are the demand numbers?

They are estimates inferred from marketplace signals, not marketplace-reported sales. Use them to rank a list, not to forecast a single product's volume.

Mollie: Is iDEAL really a flat fee?

Yes, 30p per transaction regardless of the amount, which is why it is cheaper than cards on high-value baskets.

Algopix: What should I check before subscribing?

Which marketplaces and which country sites are covered right now, and whether they are the ones you actually sell on. Coverage is the variable that decides whether the tool is useful to you.

Mollie: Can I use Mollie outside Europe?

You can accept non-European cards but at 3.25% plus 20p, and merchant accounts are aimed at European businesses. It is not a global processor.

Algopix: Does it account for marketplace fees?

It nets estimated fees and shipping off the sale price, but the fee schedule it uses is only as current as its last update, so verify the fee assumptions for your category before trusting a thin margin.

Mollie: Does Mollie do interchange plus?

Not publicly. The published rates are blended, so falling interchange does not flow through to you automatically.
