Best Free Shopify Discount App 2026: Full Comparison

Most "free" discount apps cap features fast. Here's what's actually free, what isn't, and where a Shopify Functions app changes the math.
"Free plan available" shows up next to almost every discount app in the Shopify App Store. What that free plan actually includes varies wildly, capped campaigns, capped monthly discounted revenue, features locked behind a paid tier the moment you need them.
This breaks down what "free" really means across the category, and where a discount app built on Shopify's newer Functions framework changes what free can include.
What should a free Shopify discount app actually include?
A genuinely useful free discount app should cover automatic discounts (no code required), at least one advanced discount type beyond basic percentage-off, and real-time application at checkout, without a monthly discounted-revenue cap that forces an upgrade the moment a promotion works. That last part is where most "free" plans quietly stop being free. Several established discount apps cap free-tier discounted revenue around $1,000/month, meaning a successful promotion is exactly what triggers the upgrade prompt.
Common free-plan restrictions across the category: limited active campaigns (often 1-3), development-store-only free access with paid plans required for live stores, and feature gating that reserves advanced targeting (customer tags, segments, multi-condition logic) for paid tiers. Shopify's own App Store discounts category lists over a thousand apps under Marketing and Conversion → Discounts, most advertising a free plan, so the volume alone makes it hard to tell which "free" is actually free without checking each one's fine print.
Why do so many "free" discount apps still cost money eventually?
Most discount apps built before Shopify Functions became standard rely on separate backend infrastructure to run their logic, and that infrastructure has real operating costs the app has to recover somewhere, which is why free tiers are usually capped by revenue, campaign count, or feature access. Apps built directly on Shopify's Discount Function API have a structurally different cost profile: the discount logic runs on Shopify's own infrastructure rather than the app's separate servers, which is part of why some Functions-based apps can offer a fuller free tier without the same infrastructure cost pressure.
This isn't true of every Functions-based app, plenty still charge, but it's worth understanding as context for why pricing varies so much across apps that look similar on the surface. Shopify's own collection of discount apps built on the Functions framework lists 30 apps at last count, with pricing ranging from fully free to subscription tiers well past $50/month, all running on the same underlying infrastructure.
What does Flowly include on its free plan?
Flowly: Discount Functions is free with no revenue cap, covering all three discount classes (product, order, shipping), all four discount actions, and all 12 condition types, since the app doesn't have a paid tier at all. It's a Subscribfy app built specifically as a no-code layer over Shopify's Discount Function API. That means:
Product, Order, and Shipping discount classes — covering cart line items, order subtotals, and delivery options in one builder.
Four actions — Percentage Off, Fixed Amount Off, Free Shipping, and Buy X Get Y (bundles and free gifts without a separate coupon system).
Twelve condition types — cart subtotal, item count, line quantity, line price, product tag, product vendor, collection, variant SKU, delivery country, customer segment, customer tag, and order count, combinable through AND/OR/NOT logic.
Selection strategies — First, All, Maximum, or Minimum, to control what happens when more than one rule could apply to the same cart.
It launched specifically to give merchants a way to rebuild Shopify Scripts-style logic after Scripts stopped executing on June 30, 2026, without paying a monthly fee for something that used to be free (if you had a developer).
How does the category compare?
The free-Shopify-discount-app category splits into three real groups: apps with a genuine no-cap free tier for basic discount types, apps with a capped or limited free tier that pushes toward a paid plan quickly, and Functions-based no-code builders where the free tier covers the underlying logic itself rather than a merchandising layer. Established names in the space, apps like Kite, FAD Automatic Discounts, and Bundle-focused tools, generally fall into the first two groups: solid free entry points for BOGO, bundles, and volume discounts, with storefront widgets (progress bars, tier tables, badges) as a differentiator, often gated to paid tiers once usage climbs.
Flowly sits in the third group. It doesn't do storefront merchandising, no cart-drawer widgets or on-page pricing tables, it's the discount logic layer. If you want both the logic and the visual merchandising, pairing Flowly's rule-building with a display-focused app, or choosing an all-in-one paid app if budget allows, covers more ground than either alone.

FAQ
Is Flowly really free, or is there a hidden paid tier?
Flowly is free to install from the Shopify App Store, with all discount classes, actions, and conditions available without a separate paid plan.
Do free Shopify discount apps work on Shopify Plus?
Most do, since app-based Functions work across every Shopify plan, not just Plus, per Shopify's own documentation on Functions distribution. Plus-exclusive advantages generally apply to custom-built Functions, not app-based ones.
What's the real difference between a free discount app and a paid one?
Usually storefront presentation (widgets, tables, badges), advanced analytics, and customer support responsiveness. The underlying discount mechanics, percentage off, BOGO, tiered pricing, are increasingly available free once built on Shopify's Functions infrastructure rather than older, separately-hosted logic.
Do free discount apps affect checkout speed?
Not meaningfully, if they're built on Shopify Functions. Shopify's own performance documentation confirms discount functions execute in a tightly controlled window regardless of which app delivers them, since the logic runs on Shopify's infrastructure rather than a separate server the app maintains. Older, non-Functions discount apps that rely on theme scripts or external API calls don't carry the same guarantee.
Can I use more than one free discount app at the same time?
Technically yes, but running multiple discount apps increases the risk of conflicting rules and unintended stacking, since Shopify's discount combination rules apply regardless of which app created each discount. Consolidating logic into fewer apps generally reduces that risk.
"Free" is doing a lot of work in most discount-app marketing. Check what the free tier actually covers before assuming it matches your use case. Download Flowly directly from the Shopify App Store to test the free plan yourself, or book a call with Subscribfy's team if you want help figuring out whether the logic gap is worth a paid app instead.
