If you're Googling "Rebuy alternative," you probably already know what Rebuy does well. You're here because something isn't working, and for most merchants, that something can be their AI not working out for you or their pricing being too high for the value they provide.
Rebuy's modular pricing structure means costs stack up fast. Need recommendations, checkout upsells, and search? That's three separate packages, each scaling with your order volume. A mid-size store can easily hit $300-$500/month before adding premium support ($499/month extra). For merchants doing $100K-$500K/month in revenue, that math starts looking uncomfortable, especially when you're not sure how much of the attributed revenue would have happened anyway.
We build PersonalizerAI, a Rebuy competitor in the recommendation and search space, so we know this category well. This post covers five alternatives worth evaluating, with honest pros and cons for each. We'll tell you where each one beats Rebuy and where it falls short.

1. PersonalizerAI
Best for: DTC brands doing $50K-$2M+/month who want recommendation quality and search in one app, with pricing that scales to actual results.
PersonalizerAI combines AI-powered recommendations and AI search in a single platform. Each store gets bespoke models trained on its catalog structure, order history, and customer behavior patterns, rather than generic collaborative filtering that treats every store the same.
Pricing: $29.99/month base plus a commission on AI-attributed revenue, tiered down as revenue grows (5% on the first $1,999, down to 2% on everything above $10,000). If the AI generates $5,000/month in additional revenue, you pay roughly $250 total. If it generates $200, you pay about $40. The commission is calculated on click-only attribution verified in Shopify analytics, not inflated view-through numbers.
What it does well: 11+ recommendation widget types across every store page (personalized, similar, bought together, complete the look, checkout, post-purchase). The AI search replaces Shopify's default with semantic understanding and visual search, cutting zero-result searches by up to 40%. Setup takes about 30 minutes. Every merchant works directly with the founding team.
Where it falls short: Younger product than Rebuy, so the integration ecosystem is smaller. No standalone smart cart drawer (integration within cart available) with tiered progress bars and gift-with-purchase logic like Rebuy offers. Merchants who prefer building granular manual merchandising rules rather than letting AI handle decisions may find the approach too hands-off.
Why merchants switch from Rebuy: Performance-based pricing eliminates the risk of paying $249-$999/month for results you can't verify. The AI models are trained per-store instead of relying on generic patterns, which shows up in recommendation relevance, especially for niche or complex catalogs.

Key metrics: 23-34% average AOV lift, 20-40x measured ROI, 10-25% search conversion increase.
2. Selleasy
Best for: Stores doing under $50K/month that need reliable upsell and cross-sell without a big monthly commitment.
Selleasy has the largest install base in the Shopify upsell category, with over 42,000 stores and 2,100+ reviews. The reason is simple: they've made upselling affordable and easy to set up.
Pricing: Free for stores with up to 50 orders/month. Paid plans start at $9/month (up to 500 orders) and scale to $29/month for 1,000+ orders. Pro ($49/month) and Enterprise ($99+/month) tiers add AI-powered recommendations and dedicated support.
What it does well: Frequently bought together bundles, product add-ons, cart upsells, post-purchase offers, and checkout upsells. The interface is clean, setup is fast, and you can see exactly what you'll pay at each tier. For a store that wants to add 10-15% to AOV without overthinking it, Selleasy delivers.
Where it falls short as a Rebuy alternative: The recommendation logic is primarily rule-based. You're manually building product associations rather than letting AI learn from customer behavior. There's no AI search, so you're still stuck with Shopify's default keyword matching. Merchants with catalogs over a few hundred products will hit the ceiling on what manual rules can do.
Verdict: A solid Rebuy alternative if your primary concern is cost and you don't need deep AI personalization. Not a replacement if you chose Rebuy specifically for its AI capabilities or smart cart.
3. ReConvert
Best for: Stores that want to maximize post-purchase revenue specifically, rather than replacing Rebuy's full recommendation suite.
ReConvert is a post-purchase funnel builder, not a full product discovery platform. If you're leaving Rebuy and want a complete replacement, ReConvert only covers one piece of the puzzle. But it covers that piece well, and at a fraction of the cost.
Pricing: Starts at $4.99/month for up to 50 orders, scaling to $79.99/month for up to 1,000 orders. Custom pricing above 2,000 orders. 14-day free trial on all plans.
What it does well: ReConvert places one-click upsell pages between checkout and the thank-you page, so customers can add products without re-entering payment details. The drag-and-drop funnel builder is easy to use, and the app includes thank-you page customization, birthday collection, reorder buttons, and basic product recommendations. Merchants report adding $5-$50 to their AOV. With 2,800+ reviews and a 4.8 rating, the track record is solid.
Where it falls short as a Rebuy alternative: ReConvert only handles post-purchase. No homepage recommendations, no PDP widgets, no AI search, no in-cart upsells. If you're looking for a full Rebuy replacement, you'd need ReConvert plus another app for on-site recommendations, which means managing two tools and two bills.
Verdict: Consider ReConvert as part of a stack rather than a standalone Rebuy alternative. It pairs well with a lighter recommendation app if you want to split the job across specialized tools instead of paying for one expensive platform.
4. LimeSpot
Best for: Mid-size stores that want a range of recommendation types with a mix of AI and manual control.
LimeSpot offers 12+ recommendation types across two products: Turbo (their core recommendation engine) and Max (a full personalization suite with audience segmentation, A/B testing, and email/SMS personalization).
Pricing: LimeSpot Turbo starts at $9.99/month. LimeSpot Max starts at $50/month and scales with monthly revenue ($150/month for stores doing up to $50K/month). 15-day free trial.
What it does well: Wide variety of recommendation placements with a hybrid approach that blends AI suggestions with manual merchandising rules. The Max product adds audience segmentation for showing different recommendations to different customer groups. For merchants who want more personalization control than Selleasy offers but aren't ready for enterprise pricing, LimeSpot sits in a reasonable middle ground.
Where it falls short as a Rebuy alternative: No AI search product. The Max tier pricing scales with your store's revenue, which can get expensive at higher volumes, similar to the problem that pushed you away from Rebuy in the first place. LimeSpot also has a legal history worth noting: In April 2023, Pantastic sued LimeSpot and its CEO/founder, alleging they misrepresented the capabilities of their AI-driven personalization technology. While this might not affect the product's functionality today, some merchants factor company stability into long-term platform decisions.
Verdict: A viable Rebuy alternative at the mid-tier level. The Turbo product is affordable and functional. Be cautious with Max pricing at scale; run the numbers against what you'd pay for Rebuy or a performance-based alternative.
5. Nosto
Best for: Shopify Plus merchants with dedicated ecommerce teams who need enterprise-grade personalization and have the budget for it.
Nosto is an enterprise personalization platform that covers product recommendations, site search, content personalization, and merchandising intelligence. They're the closest to Rebuy in terms of feature breadth, but positioned higher up the market.
Pricing: Custom, contact-sales-only. No public pricing. Nosto describes their model as performance-based (pay for conversions, not traffic), but the specifics are opaque until you talk to their team. Merchants report it's significantly more expensive than mid-market alternatives.
What it does well: Full-stack personalization including AI search, content personalization, and business intelligence tools that go beyond what most recommendation apps offer. The platform integrates with Shopify Markets for multi-market personalization. Merchants who need personalization across email, on-site, and merchandising in one platform will find Nosto covers a lot of ground.
Where it falls short as a Rebuy alternative: If you're leaving Rebuy because of pricing, Nosto will likely cost more, not less. The platform has a steep learning curve, and some merchants report needing developer resources for setup and customization. With only 72-88 reviews on the Shopify App Store compared to thousands for other apps on this list, the Shopify-specific adoption is relatively limited. Some user reviews cite difficulty canceling contracts and unexpected price increases.
Verdict: Nosto makes sense if you're a large Shopify Plus operation that has outgrown Rebuy's capabilities and needs enterprise personalization. If you're leaving Rebuy to save money, Nosto is probably the wrong direction.
How to choose the right Rebuy alternative
The right replacement depends on why you're leaving.
If pricing is the main issue, PersonalizerAI's performance-based model eliminates the fixed-cost risk. Selleasy is the budget option if you don't need AI depth. Run the math on what you paid Rebuy last quarter versus what you'd pay each alternative at your current volume. Factor in the revenue attribution method, because inflated numbers make expensive tools look cheaper than they are.
If recommendations feel too generic, PersonalizerAI's per-store AI models address this directly. LimeSpot's hybrid approach gives you more manual control. Selleasy and ReConvert won't solve a recommendation quality problem.
Too much complexity? PersonalizerAI and Selleasy both prioritize fast setup and low maintenance. Nosto will add complexity, not reduce it.
Only need part of what Rebuy offers? ReConvert for post-purchase, Selleasy for basic cross-sells, or PersonalizerAI for recommendations + search.
