Swish (formerly Wishlist King) vs. Swym Wishlist Plus: An In-Depth Comparison

Introduction

Choosing the right wishlist app can feel deceptively simple: the feature appears small, but the wrong choice creates technical debt, fragmented customer data, and missed revenue. Merchants must weigh setup, customization, integrations, reporting, and ongoing costs — not just the initial install.

Short answer: Swish (formerly Wishlist King) is an excellent choice for merchants who want a fully customizable wishlist with hands-on onboarding and unlimited wishlist volume, while Swym Wishlist Plus is a stronger fit for stores that need flexible APIs, built-in price/restock alerts, and a free entry point. For merchants who want to avoid tool sprawl and capture long-term value from loyalty, reviews, referrals, and wishlist in one place, a consolidated platform like Growave often delivers better value for money than assembling several single-purpose apps.

This post provides an in-depth, feature-by-feature comparison of Swish (formerly Wishlist King) and Swym Wishlist Plus to help merchants choose the best fit for their store. The analysis covers core capabilities, customization, notifications, integrations, performance, pricing, support, and recommended use cases. After the direct comparison, the article explains how an integrated retention platform can reduce complexity and improve lifetime value.

Swish (formerly Wishlist King) vs. Swym Wishlist Plus: At a Glance

Feature Comparison

Core Wishlist Capabilities

Both apps deliver the baseline merchants expect from a wishlist: shoppers can save items, return later, and be nudged to convert. Yet their philosophies differ.

Swish focuses on an unlimited experience. Every plan includes unlimited wishlists and saved items, which removes the worry of hitting usage caps as a store grows. The product messaging emphasizes a fully customizable and conversion-driven wishlist that fits across a shopper’s journey.

Swym is built around flexibility and breadth. It supports multiple wishlists per customer, anonymous wishlists, and strong sharing capabilities (email, SMS, socials, links). Where Swym stands out is the built-in alerting (price drops, restocks, low stock), which turns saved intent into timely trigger-based outreach.

How that translates into outcomes:

• Swish reduces the risk of throttled customer activity by offering unlimited saves, which is important for catalogs with high repeat save behavior or heavy social traffic.
• Swym converts saved intent via alerts. The price/restock alerts are designed to shorten the distance between interest and purchase, which can help recover otherwise lost intent.

Customization & Theming

Swish positions customization as a core strength. The offering includes a free setup and customization service across plans, with white-glove onboarding available for Plus merchants. The emphasis is on matching store aesthetics, making the wishlist feel native rather than bolted-on.

Swym emphasizes a frictionless install with theme integration that can be live in minutes. It provides APIs for deeper customization and a new Customer Accounts extension that centralizes wishlists and recent views. For merchants focused on speed and developer-driven customization, Swym’s API approach is compelling.

Practical implications:

• Merchants without developer resources who want a polished, on-brand wishlist will likely appreciate Swish’s free setup service.
• Stores with in-house development teams seeking to extend wishlist behaviors or integrate wishlists into headless experiences may favor Swym’s API access and fast initial setup.

Notifications & Conversion Triggers

Turning wishlists into purchases requires smart, timely notifications.

Swish supports highly personalized and automated wishlist notifications and lists integration with Klaviyo, GA4, and Meta out of the box. The product messaging indicates that notifications are part of the conversion workflow, but specifics on system-level alert types (e.g., price drop) are less prominent than Swym.

Swym explicitly includes email alerts for low-stock, restock, and price drops, and ties those alerts into popular ESPs. The platform’s API-first design makes these triggers programmable and enables retailers to build custom flows around alerts.

Which approach converts better depends on the merchant’s marketing stack:

• Brands already orchestrating lifecycle flows in Klaviyo and wanting simple integrations may find Swish’s prebuilt integrations efficient.
• Merchants looking to automate alerts with built-in behavior and minimal configuration will likely find Swym’s native alerting more turnkey.

Analytics & Reporting

Swish promotes "advanced analytics" and wishlist curation. The app aims to provide meaningful insights into what customers save and how those saves convert, which supports merchandising and email segmentation.

Swym provides detailed reports on shopper behavior and wishlist usage. With a larger user base and mature reporting, Swym’s analytics are built for operational visibility (e.g., which items trigger price alerts, sharing metrics).

For merchants that rely on wishlist data to inform merchandising and paid campaigns, both apps give usable reporting; Swish puts parity on curated insights and in-app consultative setup, while Swym emphasizes operational reporting and event-driven triggers.

APIs, Headless & Developer Support

Swish explicitly supports Hydrogen, headless stacks, and offers Shopify Plus exclusives on higher plans. The Plus plan adds priority support and dedicated account management for complex implementations.

Swym has REST and JavaScript APIs available on higher tiers (Premium), and Pro has retargeting & Shopify Flow integrations. Swym’s long track record and broad marketplace-ready integrations make it a natural fit for developers building bespoke experiences.

Developer considerations:

• Headless or Hydrogen stores that want a vendor to support headless architectures without custom extra work may prefer Swish’s headless-focused Plus plan.
• Teams that prefer to build custom wishlist behaviors and integrate closely with other systems will appreciate Swym’s API access and established developer docs.

Integrations & Ecosystem

Integrations determine how wishlist data feeds broader lifecycle and advertising systems.

Swish lists Klaviyo, GA4, and Meta as available out-of-the-box—and supports Customer Accounts and Hydrogen. The app’s integration list is curated toward marketing analytics and personalization.

Swym provides an extensive integration matrix: Klaviyo, Yotpo, Mailchimp, Postscript, Attentive, Tapcart, PageFly, Listrak, Omnisend, Hubspot, and more. This breadth matters for merchants using diverse ESPs, POS systems, or headless storefront builders.

Operational takeaway:

• Stores already standardized on a small set of marketing tools may prefer Swish’s focused integrations and white-glove setup.
• Merchants with an established multichannel tech stack or that plan to experiment with multiple vendors will likely gain more flexibility from Swym’s large integration footprint.

Performance & Scalability

Performance and quota management vary significantly.

Swish’s pricing model provides unlimited wishlists and sessions across plans, which simplifies forecasting and removes the need to monitor action limits.

Swym uses action-based tiers. The free plan includes 500 lifetime wishlist actions (no reset). Paid tiers start at 1,000 wishlist actions per month and scale up to 25,000. For high-touch or high-traffic stores, these action caps can require careful monitoring or higher-tier plans.

Impact on scale:

• High-traffic stores with heavy wishlist engagement will benefit from Swish’s unlimited model to avoid surprise overage behavior.
• Stores that can predict or control wishlist action usage and want to optimize spend by volume may find Swym’s tiered model more cost-efficient—until their action needs grow.

Pricing & Value

Neither app is free of trade-offs. Focus on the commercial model rather than the headline price.

Swish pricing is tied to Shopify plan tiers: $19 (Basic) / $29 (Shopify) / $49 (Advanced) / $99 (Plus). The notable selling point is that all plans include the same feature set plus free setup & onboarding, and unlimited wishlists/sessions. This model delivers cost predictability as shoppers and wishlists grow, which can be an important element of value for growing merchants.

Swym’s pricing ranges from a Free plan to $99.99/month. The free plan is useful for testing and small operations (500 lifetime actions). Paid plans include Starter ($19.99/mo), Pro ($59.99), and Premium ($99.99) with increasing monthly action limits and access to APIs. For smaller stores, Swym’s free and low-cost tiers provide a low barrier to experimentation; at scale, action limits make cost forecasting more complicated.

Value-for-money considerations:

• For merchants who value predictable and unlimited usage, Swish represents better value for money at scale because features are not gated by usage caps.
• For merchants who prioritize a free entry point, flexible APIs, and pay-as-you-grow control, Swym represents better value for early-stage setups.

Setup & Onboarding Experience

Swish offers a consultative onboarding experience and free setup across plans, which reduces the merchant’s lift, especially for stores that want the wishlist to match store design and customer experience precisely.

Swym emphasizes rapid installation and "get going in less than 5 mins" messaging. For teams that want immediate surface-level functionality and iterative customization, Swym’s speed-to-live is advantageous.

Which approach suits the store:

• Merchants without internal design or development resources who want a polished integration will appreciate Swish’s setup service.
• Merchants with developers who want to launch quickly and iterate will prefer Swym’s instant install and API approach.

Support & Customer Satisfaction

Support and responsiveness matter for conversion-critical tools.

Swish has high customer satisfaction signals: 272 reviews with a 5.0 rating suggest excellent support and product fit among its users. The Plus plan adds priority support and a dedicated account manager.

Swym has a larger review footprint—1,408 reviews and a 4.8 rating—indicating broad adoption and generally positive sentiment, especially given the higher review count. Swym’s support model includes assistance across plans and documented integrative help with popular platforms.

Interpreting ratings:

• Swish’s perfect rating (5.0) against fewer reviews suggests an intensely satisfied user base, possibly reflecting the positive impact of free setup and customization.
• Swym’s high rating across a much larger base demonstrates consistent performance and scalability, with slightly broader user diversity.

Security, Privacy & Compliance

Both platforms integrate with customer accounts and support anonymous wishlists. The key merchant considerations are data ownership and exportability, especially when integrating with CRMs or ESPs.

Swish and Swym both integrate with major email and analytics platforms to move wishlist events into owned systems. Merchants should confirm data retention, export formats, and GDPR/CCPA support during onboarding.

Migration, Implementation & Operational Considerations

Switching wishlist providers is common during a store’s growth. Key migration checkpoints:

• Data migration: Can wishlists and customer associations be exported/imported? Swish's free setup may help with migration mapping. Swym’s APIs can automate migration workflows but may require dev resources.
• Front-end continuity: How will theme-level wishlist UI be preserved to avoid UX regression? Swish’s customization service can replicate on-brand components. Swym's quick install may require additional theme work to match prior styling.
• Marketing automation: What flows must be recreated in Klaviyo or other ESPs? Both apps integrate with Klaviyo, but merchants should map triggers (save item, price alert, restock, purchase) and confirm how events are named.
• Cost forecasting: Swym's action quotas can be an operational surprise if not monitored. Swish’s unlimited model removes that variable but contains other costs if advanced services are required.

Practical checklist for a migration:

• Export wishlist data from the current app.
• Confirm import format and API endpoints with the destination app.
• Recreate automation flows in the ESP and test triggers end-to-end.
• Validate anonymous wishlist linking to customer accounts.
• Test high-traffic scenarios and sharing links on social platforms.

Real-World Use Cases

Below are neutral recommendations about which merchants will find each app a stronger fit.

Swish is best for:

• Brands that require a cohesive, on-brand wishlist tied into merchandising and conversion analytics.
• Merchants that prefer predictable costs and infinite wishlist capacity as they grow.
• Stores without dedicated frontend developers that want vendor-managed setup and configuration.
• Shopify Plus or Hydrogen/headless merchants who want vendor support for complex experiences and white-glove onboarding.

Swym Wishlist Plus is best for:

• Merchants who want a free entry point to test wishlist behavior and sharing.
• Stores that value built-in price drop, restock, and low-stock alerts to reactivate intent.
• Teams with developers who want API-first platforms to integrate wishlist events into custom flows.
• Merchants running diverse marketing stacks who need broad third-party integrations.

The Alternative: Solving App Fatigue with an All-in-One Platform

Wishlist apps solve an important conversion problem, but adding a single-purpose tool for every lifecycle need creates app fatigue. App fatigue includes rising monthly costs, fragmented customer signals, multiple integrations to maintain, and increased complexity for headless or enterprise stores.

Common problems from using multiple specialized apps:

• Fragmented Data: Wishlist events live in one tool, loyalty points in another, reviews in a third, making cohesive segmentation and personalization difficult.
• Integration Overhead: Each app introduces connectors to ESPs, CRMs, and analytics, increasing the risk of broken data syncs.
• Cost Creep: Multiple subscriptions and action-based pricing create unpredictable monthly bills.
• Technical Debt: Theme customizations, script tags, and headless hooks stack up and complicate updates.

"More Growth, Less Stack" is a practical alternative: consolidate retention functions into a single platform to manage loyalty, reviews, wishlists, and referrals together. An integrated approach simplifies data ownership, reduces monthly vendor overhead, and accelerates time-to-value from cross-product use cases (for example, rewarding wishlist saves with loyalty points or embedding reviews into post-purchase wishlist follow-ups).

Growave positions itself around that idea. It bundles Wishlist with Loyalty & Rewards, Referrals, Reviews & UGC, VIP Tiers, and more into a single retention suite. For merchants evaluating whether to add a wishlist or to rethink their tool set, the benefits of consolidation include:

• Unified customer profiles: Wishlist saves, review activity, referral behavior, and loyalty points feed the same customer record, which enables precise segmentation.
• Less integration work: One platform integrates with common ESPs and CRMs so syncing is centralized rather than scattered.
• Predictable growth: Consolidated plans can be more cost-effective than multiple single-use subscriptions as a store scales.
• Faster experimentation: Tools like loyalty and wishlist interoperate out of the box, enabling campaigns that combine mechanics (e.g., reward a wishlist save during a product launch).

Growave’s positioning is built on those principles. Merchants interested in assessing an integrated approach can review plans and cost comparisons to estimate consolidated spend and ROI by visiting Growave’s pricing page for plan details and trial options. For merchants who want to evaluate app installation via the Shopify ecosystem, Growave is available on the Shopify App Store.

How Growave maps to function gaps highlighted in the Swish vs. Swym comparison:

• Onboarding & Customization: Growave provides guided onboarding and customization options that reduce the setup lift of multiple vendors. For merchants that valued Swish’s white-glove setup, Growave’s onboarding can deliver similar benefits while covering more retention touchpoints.
• Alerts & Automation: Growave’s ecosystem integrates with email and SMS partners to support alerting strategies similar to Swym’s price/restock flows, but within the same data model that powers loyalty and referral campaigns.
• Integration Breadth: Growave connects with the major ESPs and storefront builders that merchants rely on, centralizing events that are otherwise split across multiple apps.

For merchants seeking evidence of how customers use integrated solutions, Growave shares customer stories and real brand examples that demonstrate cross-product strategies and outcomes.

If the key objective is to consolidate retention features and minimize app overhead, merchants can:

• Evaluate how wishlist data is currently consumed by marketing and merchandising teams.
• Map the lifecycle flows that would benefit from an integrated data model (e.g., reward wishlist activity, use wishlist data to send targeted review requests).
• Compare the combined monthly cost of single-purpose vendors to an integrated plan and include estimated labor savings from lower integration overhead.

For a quick assessment, merchants can consolidate retention features and compare how much would be saved by moving wishlist, reviews, and loyalty into one platform. For stores that prefer installing from the Shopify marketplace, Growave’s app listing is available on the Shopify App Store to simplify the onboarding step.

How Growave Replaces Multiple Point Solutions

Growave replaces several single-purpose apps by offering:

• Loyalty and rewards programs tied to behavior and purchases.
• Wishlist functionality that integrates with loyalty and lifecycle automation.
• Referrals and affiliate mechanics built into the same customer model.
• Reviews and social proof workflows to capture and publish UGC.
• VIP tiers to prioritize high-LTV customers.

Merchants can explore how to build loyalty and rewards that drive repeat purchases and how to collect and showcase authentic reviews without installing multiple integrations.

Integration Strategy and Practical ROI

An integrated platform reduces the number of connectors and scripts that must be maintained. Real ROI often arrives from better-targeted email flows and fewer lost data points when segmentation and personalization pull from a single customer record.

Merchants can evaluate ROI by:

• Calculating the incremental revenue from converting wishlists with automated alerts or loyalty nudges.
• Estimating monthly savings from consolidating subscriptions.
• Valuing the time saved by having one platform for support, updates, and design changes.

For enterprise or Shopify Plus brands, Growave offers Plus-level support and custom launch planning, similar to Swish’s Plus plan, but across a wider product set. Merchants that need Plus-level services for retention across loyalty, reviews, wishlist, and referrals will find that a single vendor reduces coordination time and often accelerates campaign launches.

Growave’s presence on the Shopify App Store makes it straightforward to install, or merchants can review plans directly to estimate fit on the pricing page. For merchants who prefer to see live examples, Growave publishes customer stories from brands scaling retention that highlight cross-product strategies.

Implementation Scenarios and Migration Tips

For merchants convinced to move from single-purpose wishlists to an integrated approach, practical steps include:

• Audit current vendor list and map overlapping features.
• Export wishlist, loyalty, and review data where possible.
• Plan a phased migration to minimize disruption: import wishlists first, then switch loyalty and review capture.
• Communicate customer-facing changes, especially if wishlist URLs or sharing links will change.
• Test end-to-end flows, including email/SMS triggers for price changes, loyalty rewards, and referral flows.

For merchants exploring Growave, reviewing the pricing page and the Shopify App Store listing provides the path to trials and installation. If a tailored walkthrough is preferred, a demo can clarify how existing wishlist events map into combined retention strategies.
