Why Shopify stores look for a Monk alternative

Monk (4.9 from 600 reviews) is a Built for Shopify app combining free gift with purchase, BOGO, cart upsells and a tiered progress bar across product page, cart, checkout and post-checkout. The most common reasons stores look elsewhere:

• Priced by total store orders. $49 a month up to 1,000 orders, then $149 — the price follows your order count, not upsell results.
• Gift and BOGO focus. Stores that want deeper checkout customizations, subscription upgrades or holdout testing look elsewhere.
• Newer pricing offer. The $1 first month is a promotion; ongoing plans start at $49 a month.

For free gifts, BOGO and cart upsells in one well-reviewed app, Monk is still a strong choice — its 4.9 rating is among the highest here.

The 5 best Monk alternatives

1. UpsellPlus

Choose it over Monk if: You want free gifts, cart upsells and rewards bars plus Shopify Plus checkout offers, post-purchase funnels and subscription upgrades, priced on upsell revenue rather than store orders.

Rating: 5.0 (146) on the Shopify App Store.

• Offers chosen by hand, from collections or tags, or automatically by ShopBrain (similar, complementary, subscription upgrade, size upgrade, complete the set, clearance and more)
• Upsells to subscriptions with Shopify Subscriptions, Recharge, Appstle, Seal, Skio, Stay AI and other selling-plan apps

No commission on sales; 14-day free trial on paid plans.

Watch out for: Checkout placements need Shopify Plus, as with every app that offers checkout upsells (a Shopify restriction).

2. iCart

Rating: 4.7 (451) on the Shopify App Store.

Pricing: Free for the first 100 orders (lifetime). Then $9 (0–100 orders), $19 (101–200) and $29/month (201–500).

Watch out for: Cart-focused; checkout and post-purchase offers aren't listed.

3. Monster Cart Upsell

Choose it over Monk if: You want cart upsells, free gifts and one-tick add-ons on a free or low-cost plan.

Rating: 4.7 (537) on the Shopify App Store.

Pricing: Free up to 50 orders (launch offer). Starter $9.99 (51–200 orders), Scaler $14.99/month and up. 10-day free trial.

4. Upcart

Choose it over Monk if: You want a fully customizable slide cart with upsells and a rewards bar from a larger vendor (Rokt).

• Upsells and add-ons modules
• Rewards module with a free-shipping bar

• Custom HTML and CSS

Pricing: $29.99/month up to 200 monthly store orders, then $34.99, $54.99 and higher as orders grow. 14-day free trial.

Watch out for: Priced by total store orders, and it covers the cart only, so checkout and post-purchase need another app (such as Aftersell).

Rating: 4.8 (677) on the Shopify App Store.

How to switch from Monk

1. List your live Monk offers and how much revenue each brings in.
2. Rebuild the top earners first in the new app, on the same placements.
3. Turn off Monk's offers when the new ones go live, so shoppers don't see duplicates.
4. Compare upsell revenue and AOV against your old baseline; a holdout test shows what the new offers actually add.
