Best Free Upsell Apps for Shopify (2026)
The best free upsell app for Shopify in 2026 is Libautech AI Post Purchase, our own app, because it is free as its pricing model rather than a limited trial: Claude reads each order and shows a one-click post-purchase upsell automatically, with no funnel building, no order caps and no revenue share. It is new, so weigh that. For the strongest free plan, Essential Upsell & Cross Sell is a 5.0 across thousands of reviews; Selleasy is free to install; Upsell.com (formerly ReConvert) has a free plan with deep post-purchase; Wiser is free to install with email recommendations; and Shopify Bundles is Shopify's own free native bundler.
Key takeaways
- "Free" on the App Store means three different things: free forever, a free plan with caps, and a free trial. This list is explicit about which is which, because the difference decides whether your setup survives your first good sales month.
- We make Libautech AI Post Purchase and rank it first because it is free forever, not a capped plan, which is the truest fit for "best free." It is new with few reviews yet, and it is post-purchase only, so we say so plainly.
- The most-proven genuinely free options are Essential (a 5.0 free plan across 2,000-plus reviews) and Selleasy (free to install, 4.9 across 2,478). If public proof matters most, start with those.
- Do not build your average order value system on a free plan with a low order cap. Re-platforming during your first successful month is the worst possible time.

What "free" actually means in upsell apps
Three models hide behind the same word, and the difference is the whole story.
Free forever. The app's business model does not charge you for the core product. Libautech AI Post Purchase and Shopify's own apps work this way. There is no order cap tied to a subscription and no revenue share, so the app does not become a bill as you grow.
Free plan. A capped tier, usually limited by monthly orders or features, designed to convert you to paid as you scale. Most cart, bundle and upsell apps offer one. It is a genuine way to start, but building your core offers on a 50-order cap means re-platforming during your first good month.
Free to install. No monthly fee to install and run, but you may pay a usage or revenue-share fee as the app generates sales. Selleasy and Wiser sit here. The fee is invisible at launch and grows with success, so price it at your real volume.
None of these is bad. But "best free" should mean the model you will not outgrow the moment it works, which is why we lead with free forever.
Who each free option is for
| Your situation | Best free pick | Why |
|---|---|---|
| Want revenue with zero ongoing cost | A free-forever app | No cap, no revenue share, nothing to outgrow. |
| Want the most proof behind a free plan | A high-rated free plan | Thousands of reviews on a genuine free tier lower the risk. |
| Fine paying only as you scale | A free-to-install app | Nothing upfront; a fee arrives with the sales it makes. |
| Want free pre-purchase bundles | Shopify's native app | First-party, free forever, real product bundles with inventory sync. |
How we ranked these, and a word on bias
The disclosure first. We make Libautech AI Post Purchase, and we rank it first, so read this with that in mind. We rank it first on one specific axis: it is free forever, with no order cap and no revenue share, which is the truest reading of "best free upsell app." Being straight about the trade-offs: it is a new app with few reviews yet, and it does one thing, post-purchase, so it has none of the product-page or cart coverage the others carry. If public proof or breadth matters more to you than the pricing model, Essential and Selleasy are the stronger picks, and we say so in the best free app for each situation section. Our figures are read from the live App Store listing, same as everyone's.
The criteria we score on: which kind of free it is and whether you will outgrow it; how much it actually covers for free; the depth of public proof; and whether a fee arrives at volume. Ratings and review counts are from the Shopify App Store as of August 2026.

1. Libautech AI Post Purchase
AI Post Purchase (our app) is free with no order caps tied to a subscription and no revenue share. Install it, approve which products may be offered, and Claude selects one upsell per order, shown between payment and the thank-you page, where accepting is a single click with no card re-entry. Because the offer fires after payment, it cannot hurt the conversion that already happened.
Strengths: genuinely free forever, no funnel building, and zero risk to the sale because it runs post-purchase.
Watch-outs: we will be straight, it is a new app with few reviews yet, so it has none of the public proof the specialists carry, and it is post-purchase only, with no product-page or cart placements.
Best for: stores that want a free-forever post-purchase upsell live in minutes, with no ongoing cost.
2. Essential Upsell & Cross Sell
Essential (5.0 across more than 2,199 reviews, Built for Shopify) pairs a genuine free plan with the highest rating on this list, covering product page, cart and post-purchase upsells.
Strengths: the strongest free plan on the list, near-perfect rating, and full-journey coverage for a store that wants breadth without paying upfront.
Watch-outs: the free tier is capped, so heavy use pushes you to a paid plan as you grow.
Best for: stores that want the most-proven free plan with room to grow. Free plan, then from $9.99 a month.
3. Selleasy
Selleasy (4.9 across roughly 2,478 reviews, Built for Shopify) is free to install and covers frequently bought together, add-ons and in-cart upsells, so a growing store can run real upsells before paying a monthly fee.
Strengths: excellent value and a deep, positive review base across the core upsell surfaces.
Watch-outs: free to install is not free forever; paid plans arrive as you scale, so check the tier that matches your volume.
Best for: value-focused stores fine with paying as they grow. Free to install, paid plans from $9 a month.
4. Upsell.com (formerly ReConvert)
Upsell.com (4.8 across more than 2,700 reviews, Built for Shopify) is the most-proven app here and has a free plan, with its depth on the thank-you page, where one-click post-purchase offers run after payment at zero risk to the sale.
Strengths: the deepest track record on this list, and a free plan into the strongest post-purchase toolkit.
Watch-outs: the free plan is capped by orders, and some paid tiers add a fee on generated revenue.
Best for: stores that want a proven free post-purchase start. Free plan, then from $4.99 a month.
5. Wiser
Wiser (4.9 across 513 reviews) is free to install and combines product-page recommendations with email recommendations and recently-viewed widgets.
Strengths: useful when you want free on-site upsells that also follow the shopper into email.
Watch-outs: free to install rather than free forever, and it does not build finished offers or carry the Built for Shopify badge.
Best for: stores investing in retention alongside free on-site upsells. Free to install, then from $9 a month.
6. Shopify Bundles
Shopify's own bundles app (2.8 across 543 reviews) creates fixed bundles and multipacks straight from the admin, on every plan, at no cost. Each bundle becomes its own product with its own price and SKU, and component inventory syncs automatically.
Strengths: first-party, free forever, and the cleanest zero-cost way to raise order value before checkout.
Watch-outs: fixed bundles only, no cross-sell recommendations or post-purchase, and the modest rating reflects merchants wanting more flexibility.
Best for: stores that want free, native, pre-purchase bundles with reliable inventory.

Which free upsell app is right for you?
Every option here is genuinely free. Pick what matters most and we will name the best fit, and say which kind of free it is.
Common mistakes with free upsell apps
Building on a low order cap. A free plan capped at 50 orders forces a migration during your first good month, the worst possible time. Prefer free forever, or a plan whose cap you will not hit soon.
Ignoring the revenue-share fee. Free to install can still cost a percentage of the sales it makes. Price it at your real volume, not today's.
Confusing a free trial with free. A 7 to 30 day trial of a paid product is not a free app. Read the pricing tab, not the "free" tag.
Stacking free apps that each inject scripts. Three free apps for product page, cart and post-purchase still add three scripts. Fewer apps across the journey is lighter.
What a free upsell is worth
Even a free post-purchase upsell adds real revenue. Put in your monthly orders, the share who accept, and what an accepted offer adds, to size it.
Extra revenue a month
$1,000
Extra revenue a year
$12,000
That is about 50 accepted offers a month at $20 each, all of it added after the sale is already won, so it carries no risk to the original order. It is gross added revenue before any offer discount. You can run the post-purchase offer free with Libautech AI Post Purchase.
