Lasso vs CrispCheckout vs Pendym
A fair side-by-side of the three tools that put a Whop-powered checkout on a Shopify store: how each connects, pricing as published, setup effort, custom domains, subscriptions and languages.
Updated 19 September 2026 · 7 minute read
Three tools put a Whop-powered checkout in front of a Shopify store: Lasso, CrispCheckout and Pendym. We make one of them, so read this knowing that. To keep it fair, every cell about a competitor comes from that company's own public pages or from Whop's documentation, checked on 19 September 2026, and where we could not verify something the cell says "not published" instead of guessing.
A note on sources. Lasso's own website did not load when we checked on 19 September 2026, so nothing here is taken from it. What follows comes from the integration guide for Lasso that Whop published in its documentation. That page has since been removed from Whop's docs, so we read the copy archived in April 2026, which is linked at the end. Details may have changed since then. Confirm anything that matters with Lasso directly.
The comparison table

When Lasso is the better choice
Lasso is the integration Whop itself documented, with Whop staff involved in onboarding. Whop's archived guide described negotiated terms for stores with high volume and low dispute rates. If you run a large store, want a direct relationship with Whop's team, or want to route between several processors and not only Whop, Lasso is built for that and Pendym is not.
When CrispCheckout is the better choice
CrispCheckout lets you build and test the whole checkout for free before paying, and its builder lists conversion blocks such as timers, testimonials and raw HTML. It lists Apple Pay and Google Pay, and its subscription plan lists free trials and a self-serve customer portal. If those are central to how you sell, it has them on its feature list today.
When Pendym is the better choice
- You do not want a monthly fee. At $10,000 a month in sales, 0.5% is $50 and that is the whole bill from Pendym.
- You sell subscriptions and do not want them on a higher plan.
- You sell in more than one language. The checkout is translated into 18 and follows the buyer's storefront language.
- You want pricing at the checkout to be Shopify's own: live shipping rates, tax, discount codes and Markets currencies.
- You want to try it without committing. Nothing changes for buyers until you paste the theme line, and one switch in Settings turns it off.
What all three have in common
Whichever checkout you pick, the money runs through Whop, and Whop has its own rules. It publishes a list of prohibited and restricted businesses, it reviews accounts at several points including first payment and first payout, and it can place a rolling or fixed reserve on an account it considers risky. No checkout tool in front of Whop changes that, and none is a way to sell something a processor does not allow.
All three also replace the checkout page and do not add a gateway inside Shopify's checkout, which means anything that lives on Shopify's checkout page stops applying. With Pendym specifically, the Shop Pay, PayPal and Google Pay express buttons in the cart are hidden while it is on, and Shopify gift cards cannot be redeemed at the checkout.
If Pendym is the one that fits, setup is four steps and there is no monthly fee.
