Free Shopify Apps to Increase Sales: 11 Genuinely Useful Free Tools (+ 1 Paid Pick)

Most "free" Shopify apps are bait. The free tier is a glorified trial that limits the app to uselessness, pushing you to upgrade within days. A few apps, however, offer free plans that are genuinely useful for small and growing Shopify stores: apps you can install, leave on the free tier indefinitely, and get real conversion value from.

This guide covers 12 such free Shopify apps, including Eevy AI (which we include because merchants searching for "free conversion tools" almost always also ask "is there a free way to optimize how my reviews display?"), and since Eevy added a permanent free plan, the answer is yes. Each entry covers what the free plan actually includes, the limitations, and when (if ever) the upgrade is worth it. For paid-tier picks ranking the best conversion app for Shopify and best CRO app for Shopify, see those companion pieces with honest comparisons across price tiers.

How "Free" Actually Works on Shopify

Three patterns are common in Shopify app pricing:

1. Genuine free plans: full functionality at zero cost up to a usage cap (orders, contacts, sessions). When you exceed the cap, you upgrade or stop using the feature.
2. Free trials disguised as free plans: the "free plan" is so limited it is unusable, designed to force upgrade within the trial period.
3. Freemium with paywalls: basic display works for free, but anything that actually drives conversion (analytics, customization, integrations) requires a paid plan.

Apps 1-11 below are all in category 1, limited but functional free plans that small stores can run indefinitely. App 12 (Eevy AI) also belongs in category 1 now: its free plan includes every feature up to 25,000 monthly visitors, which covers most small stores indefinitely.

The 12 Free Apps Worth Installing

1. Judge.me (Reviews)

Free plan includes: Unlimited review requests via email, photo reviews, basic widget, Google Shopping rich snippets, review import from other apps.

Limitations: Single review form, basic widget styling, no video reviews, limited customization.

Why it is genuinely useful: Reviews drive 15-30% conversion lift. Judge.me's free plan covers the full collection-and-display loop, which is rare in this category. Most other review apps cap free plans at a few hundred reviews or require an upgrade for any meaningful display widget.

Realistic impact: Same as any review app. 10-25% conversion lift once you have 5+ reviews per top product.

2. Hextom Free Shipping Bar

Free plan includes: Unlimited shipping bars, geolocation targeting, schedule rules, full customization.

Limitations: None significant for the core feature.

Why it is genuinely useful: Free shipping bars increase both AOV and conversion rate. Hextom's free plan is fully functional, not a trial.

Realistic impact: 5-10% lift in revenue per visitor when properly configured (set the threshold just above your current AOV).

3. Klaviyo (Email Marketing)

Free plan includes: Up to 250 contacts, all email marketing features (campaigns, automations, segmentation, abandoned cart, welcome series).

Limitations: 250-contact cap. Once you exceed it, the cheapest paid plan is $20/mo.

Why it is genuinely useful: Email marketing pays for itself many times over. Abandoned cart automation alone typically generates 5-15% revenue lift. Free for stores with under 250 customers means you can build the full email infrastructure before paying anything.

Realistic impact: 10-20% revenue lift from email automation, especially abandoned cart and welcome series.

4. Shopify Email

Free plan includes: 10,000 free emails per month, then $1 per 1,000 additional. Built into Shopify directly.

Limitations: Less sophisticated automation than Klaviyo. Limited segmentation.

Why it is genuinely useful: Zero setup friction (already in your Shopify dashboard), generous free tier, integrates seamlessly with product and customer data. Good starting point if Klaviyo feels like overkill.

Realistic impact: Lower than Klaviyo for sophisticated stores, but the simpler interface means many stores actually use it (vs setting up Klaviyo and never sending campaigns).

5. Smile.io (Loyalty)

Free plan includes: Points program with up to 200 monthly orders, basic referral program, customer dashboard.

Limitations: Capped at 200 monthly orders, limited customization, Smile.io branding visible.

Why it is genuinely useful: Loyalty programs increase repeat purchase rate by 20-40% for stores that have any repeat-purchase behavior at all. Smile.io's free plan is enough to validate whether loyalty drives real lift before paying.

Realistic impact: Best for stores with consumable or replenishment products. Effectively zero lift for one-time-purchase categories.

6. Privy (Email Capture + Pop-ups)

Free plan includes: Email capture popups, signup forms, basic email automation, up to 100 contacts.

Limitations: 100-contact cap is very tight. Branding visible. Limited templates.

Why it is genuinely useful: For stores that want to test whether email capture popups work without committing to a paid tool, the free plan covers the basics. Most stores outgrow it within weeks.

Realistic impact: Email capture rates of 2-8% on visitors, depending on offer and timing.

7. Trust Hero (Trust Badges)

Free plan includes: Unlimited trust badges, payment method icons, security badges, full customization.

Limitations: None significant.

Why it is genuinely useful: Trust badges in the cart and checkout area lift conversion 2-4% for unknown brands. Trust Hero's free plan is fully functional.

Realistic impact: 2-4% lift, diminishing rapidly past 3-4 badges.

8. Plug In SEO (SEO Audit)

Free plan includes: Basic SEO audit, on-page recommendations, broken link detection.

Limitations: No automated fixes, limited reporting.

Why it is genuinely useful: Identifies obvious SEO issues (missing meta descriptions, broken links, oversized images) without paying for an SEO platform. Most small stores discover 20-50 fixable issues on first audit.

Realistic impact: SEO improvements compound over months. The audit itself does not lift conversion immediately, but the fixes drive long-term organic traffic.

9. Shopify Inbox

Free plan includes: Unlimited customer chat, automated responses, integration with Shopify customer data.

Limitations: Limited to Shopify Inbox channel (no multi-channel inbox). No advanced chatbots.

Why it is genuinely useful: Live chat lifts conversion 3-8% when staffed. Inbox is built into Shopify, integrates with order data, and is genuinely free. The catch: you have to actually respond to messages.

Realistic impact: Only as good as your response speed. Worthless if you cannot respond within 5 minutes during business hours.

10. Page Speed Optimizer (Free Version)

Free plan includes: Basic image lazy-loading, JavaScript deferral, Core Web Vitals reporting.

Limitations: Advanced optimizations require upgrade.

Why it is genuinely useful: Page speed lifts conversion measurably. Even basic lazy-loading and JS deferral can recover 1-2 seconds of load time on a typical Shopify store.

Realistic impact: 5-10% conversion lift for stores currently failing Core Web Vitals.

11. Shopify Forms

Free plan includes: Email signup forms, popup forms, integration with Shopify Email and customer data.

Limitations: Less sophisticated than dedicated form apps.

Why it is genuinely useful: First-party form data flows into Shopify customer profiles automatically, no integration setup needed. Better than third-party forms for stores already on Shopify Email.

12. Eevy AI (Free Up to 25,000 Monthly Visitors)

Eevy AI has a permanent free plan covering stores up to 25,000 monthly visitors, every feature included, no credit card required to install. We are including it here because it answers the most common follow-up question merchants searching for "free Shopify apps" ask: "is there a free way to optimize how my reviews display?" The answer is now yes, for any store under the visitor cap.

Free plan includes: Full self-optimizing review section, all 22+ layout types, the genetic algorithm active from day one, free import from Judge.me / Loox / Yotpo / Stamped / Reviews.io.

Above 25K monthly visitors: Paid plans start at $99/mo (Starter), each with a 14-day free trial.

Why it is genuinely useful: Most review apps stop at "display reviews." Eevy AI layers a genetic algorithm on top that continuously tests display configurations against your real traffic. The free plan is enough to see whether automated layout optimization moves your conversion rate, at $0, indefinitely, until your traffic outgrows it.

Realistic impact: 5-15% additional lift on top of standard review display, compounding as the algorithm learns from your traffic.

What "Free" Stack Actually Looks Like

The most leveraged free Shopify stack for a new store:

1. Judge.me: reviews (foundation)
2. Klaviyo or Shopify Email: abandoned cart and welcome series
3. Hextom Free Shipping Bar: AOV and conversion lift
4. Trust Hero: checkout trust signals
5. Shopify Inbox: chat (if you can respond)

Total monthly cost: $0. Combined expected lift: 15-30% conversion improvement vs an unoptimized baseline.

When you eventually need to upgrade, pick the upgrade that addresses your biggest remaining gap, not the most-talked-about app. The best Shopify apps to increase conversion rate full ranking covers paid options by impact tier. For very small stores still on the free stack, the conversion apps for small stores guide is more directly applicable.

What Free Apps to Avoid

Some categories of free apps are common but not worth installing:

• Free "AI optimization" apps that require massive traffic to function: they will not work at small scale.
• Free heatmap apps with severely limited session capture: you cannot draw conclusions from 50 sessions.
• Free chatbots with unhelpful default flows: they damage trust more than they help.
• Free cross-sell apps with basic algorithms: typically worse than Shopify's native product recommendations.

The best free apps solve a clearly defined problem with a sensible default. The worst free apps try to do something complex (AI, automation, personalization) and need paid features to actually work.

FAQs

Are free Shopify apps actually free, or just trials?

Mix of both. The apps in this guide all have genuine free tiers, with usage caps but no time limit. Many other "free" apps are 14-day trials labeled as free plans.

Will free apps make my store look unprofessional?

Some free apps display vendor branding (Smile.io, Privy at the lowest tier). For most stores, this is fine. For premium brands where visible third-party branding clashes with positioning, the cheapest paid tier usually removes it.

How many free apps can I run before page speed suffers?

The same rules as paid apps. Each app adds JavaScript and CSS. Five or six well-built apps will not noticeably slow your store; ten poorly-built apps will. See Shopify apps that hurt conversion for the diagnostic checklist.

When should I upgrade from free to paid?

Upgrade only when you have evidence the app is producing measurable lift AND the next-tier features will produce further measurable lift. "It feels like time to upgrade" is not a reason. "We have hit 80% of the free tier cap and need to either upgrade or accept losing functionality" is.

Are free Shopify apps safe?

The apps in the official Shopify App Store undergo basic vetting. Stick to apps with 100+ reviews, 4+ star ratings, and recent updates. Avoid apps with no reviews or that have not been updated in 12+ months, even if they are free.
