SWishlist: Simple Wishlist vs. Sirius Wish: An In-Depth Comparison

Introduction

Choosing the right wishlist app is a small decision with outsized consequences. A wishlist feature can deepen engagement, reduce cart abandonment, and surface product demand—but a poorly chosen app introduces technical debt, extra monthly costs, and fragmented customer data. Merchants must weigh ease of use, customization, data limits, integrations, and long-term value when comparing single-purpose tools.

Short answer: SWishlist: Simple Wishlist is a strong pick for merchants looking for a lightweight, low-cost wishlist that scales predictably and includes meaningful localization options. Sirius Wish appears positioned as a more session- and usage-oriented tool but lacks visible social proof and clear integrations today. For merchants who want more than a single-purpose wishlist—wanting retention, reviews, referrals, and loyalty bundled together—an integrated platform can offer better value and fewer apps to manage.

This article compares SWishlist: Simple Wishlist (SoluCommerce) and Sirius Wish (Sirius Boost LTD.) feature-by-feature, plan-by-plan, and from the perspective of merchant outcomes. After a fair and detailed comparison, Growave will be introduced as an alternative for merchants who want to reduce tool sprawl and consolidate retention features.

SWishlist: Simple Wishlist vs. Sirius Wish: At a Glance

Deep Dive Comparison

This section compares the two apps across meaningful merchant criteria: core features, customization, pricing and value, integrations and technical fit, analytics and reporting, support and implementation, and ideal use cases.

Core Features and User Experience

Wishlist basics: Add, remove, share

SWishlist and Sirius Wish both focus on the basic wishlist mechanics merchants expect: customers can add and remove favorites, manage lists, and in SWishlist’s case share lists with friends. The core UX outcomes to evaluate are speed, friction of adding items, and how wishlists appear to customers across devices.

• SWishlist highlights:
  • Seamless add-to-wishlist interactions.
  • Sharing capability for wishlists — useful for gifting and social sharing.
  • Front-end supports multiple languages (up to 20 on Premium), which matters for multi-language stores.
• Sirius Wish highlights:
  • Described as supporting add/remove/manage workflows and claimed to reduce cart abandonment.
  • Plan language emphasizes sessions and wishlist actions rather than languages or sharing features.

Practical takeaway: For stores that rely on social sharing or have multilingual audiences, SWishlist’s explicit language support and sharing mention are clear advantages. Sirius Wish may still support these features, but the public description does not emphasize them.

Customization and visual integration

Customization dictates whether the wishlist feature feels native to the storefront or tacked-on. Merchants should check whether the app:

• Injects theme code or uses app blocks/sections
• Adapts to store typography, button style, and mobile/responsive breakpoints
• Allows layout changes for product, collection, cart, and quick-view templates

SWishlist advertises “Customize everything to perfectly match your store,” and offers free setup for up to two themes on the Free plan. That suggests a focus on making the feature look native without heavy merchant effort. Sirius Wish states “effortlessly integrate with your Shopify store for a cohesive user experience,” but concrete customization promises (theme setup, number of themes, developer support) are not visible in the app summary.

Practical takeaway: Merchants wanting guaranteed theme setup and visual parity should favor the vendor that documents free setup and theme support (SWishlist). For Sirius Wish, request specifics about theme compatibility and setup assistance before installing.

Wishlist persistence and accounts

Key decisions for merchants:

• Does the wishlist persist across devices?
• Is the wishlist tied to customer accounts or session cookies?
• Are there mechanisms to convert wishlist activity into marketing signals (email capture, abandoned wishlist flows)?

Neither app description details wishlist persistence strategies explicitly. This is a critical question merchants must ask pre-install: session-only wishlists are lighter but fragile (lost when cookies clear), while account-linked wishlists persist and can be tied to retention programs.

Practical advice: Before choosing, confirm whether saved items persist to customer accounts and whether wishlist events can be exported or exposed to third-party marketing tools for follow-up.

Pricing and Value

An app's sticker price is only one axis—value is the outcomes the app generates relative to cost, plus long-term maintenance and developer support expectations.

SWishlist pricing details and what they imply

• Free plan (Free)
  • 300 wishlist additions per month
  • 2 storefront languages
  • Free setup for up to 2 themes
  • Support within 24–48 hours
• Basic ($5/month)
  • 7,000 wishlist additions per month
  • 7 storefront languages
  • All Free features
  • Support within 12–24 hours
• Premium ($12/month)
  • Unlimited additions per month
  • 20 storefront languages
  • Unlimited stats
  • Priority support

Interpretation:

• Low entry cost makes SWishlist accessible to new stores.
• Clear scaling of limits (300 → 7,000 → unlimited) lets merchants forecast costs based on wishlist activity.
• Language support is a differentiator for stores with multilingual shoppers.
• Fast priority support at $12/mo is attractive for merchants needing quick fixes.

Sirius Wish pricing details and implications

• Free plan (Free)
  • 6,000 sessions
  • 100 wishlist actions
• Starter ($14.99/month)
  • 12,000 sessions
  • 1,500 wishlist actions
• Pro ($49.99/month)
  • 60,000 sessions
  • 15,000 wishlist actions
• Premium ($89.99/month)
  • 110,000 sessions
  • 60,000 wishlist actions

Interpretation:

• Plans are session- and action-based, which may align with stores that track volume by traffic. However, the relationship between sessions and revenue is indirect—many merchants prefer direct action-based limits.
• Free plan offers 100 wishlist actions but allows 6,000 sessions—this mismatch may be confusing when traffic spikes.
• Paid tiers climb quickly; mid-size stores may find the Pro tier necessary, which is more expensive than SWishlist’s Premium.

Value comparison

• SWishlist: Better for tight budgets and merchants who want predictable, unlimited additions at low cost ($12/mo). Strong multi-language positioning increases ROI for cross-border shops.
• Sirius Wish: Targeting stores that measure scale in sessions and prefer action quotas; value depends on conversion rates and how many wishlist actions convert to sales.

Practical takeaway: Evaluate your store’s wishlist action volume and traffic profile. For predictable low-cost unlimited wishlist behavior, SWishlist appears better value for money. For high-traffic stores that want usage-based segmentation, Sirius Wish may be useful but confirm what happens if thresholds are exceeded mid-month and whether overage billing is pro-rated.

Integrations and Technical Fit

Integrations determine how wishlist data flows into marketing and analytics systems—critical for monetization.

SWishlist integrations

• Works with API (explicit)
• Free setup across themes suggests some level of hands-on integration
• Multi-language support indicates attention to localization and potentially Shopify Markets compatibility

An exposed API offers pathways to export wishlist data or trigger events in external systems (email providers, CDPs, CRM). Merchants should confirm whether the API exposes events like wishlist-add, wishlist-remove, and wishlist-share, and whether webhooks are available for near-real-time automation.

Sirius Wish integrations

• “Works With:” field blank in the provided data
• No explicit API or integration claims publicly shown in the app description data provided

This absence of visible integration details is not definitive proof of lack, but it requires merchants to ask pointed pre-install questions: Is there an API? Are there webhooks? Does the app integrate with Shopify Flow, Klaviyo, or popular automation tools?

Practical takeaway: If integrating wishlist events into email flows and analytics is important, SWishlist’s explicit API mention reduces risk. For Sirius Wish, request integration documentation and ask for a sample of how wishlist events can trigger abandoned-wishlist emails or be exported to analytics.

Checkout, POS, and storefront compatibility

• SWishlist’s explicit theme setup offering indicates closer storefront integration.
• For Sirius Wish, absence of documentation means merchants should validate compatibility with checkout extensions, Ajax carts, and mobile-first themes before committing.

Analytics, Reporting, and Merchant Intelligence

Wishlist features are only as valuable as the insights they produce. Knowing which items accumulate interest helps with merchandising, restock priorities, and personalized outreach.

• SWishlist: Premium plan includes “Unlimited access to all statistics.” That suggests tiered reporting, with the ability to see comprehensive stats only at higher price points.
• Sirius Wish: The description mentions providing “valuable insights into customer preferences,” but plan details focus on session/action counts rather than reporting depth.

Practical takeaway: Merchants should ask both vendors for sample dashboards and export formats. For teams that need to connect wishlist demand directly to inventory and CRM systems, confirm whether exports or API endpoints contain customer identifiers, timestamps, and product metadata.

Support and Merchant Experience

Support is an operational risk. Delays in fixing a broken wishlist widget can directly impact conversion.

• SWishlist support SLAs are explicit:
  • Free: 24–48 hours
  • Basic: 12–24 hours
  • Premium: top priority / fastest support
  • Free setup for up to 2 themes on Free plan
• Sirius Wish public support details are not provided in the supplied description.

Practical takeaway: When evaluating smaller apps, documented support response times matter. SWishlist’s published support timeline reduces uncertainty. If Sirius Wish appeals feature-wise, verify SLA, response channels (email, chat, live), and whether onboarding help is included.

Implementation, Performance, and Site Speed

Wishlist widgets live in the storefront and can affect performance.

• Evaluate how each app injects code:
  • App blocks and Shopify Online Store 2.0 sections are the preferred modern approach—they allow merchants to add/remove the widget without editing theme code.
  • Inline script injection can increase page load times or conflict with lazy-loading and other front-end optimizations.
• SWishlist’s free theme setup implies the vendor modifies theme files or uses theme-specific integration to ensure compatibility.
• For Sirius Wish, merchants should ask whether the app uses asynchronous scripts, whether it supports app blocks, and how much additional render-blocking JavaScript is introduced.

Practical takeaway: Prioritize apps that provide clear technical documentation about how the widget is added and how much JavaScript is loaded. Run lighthouse or RUM checks after install to monitor real impacts.

Security and Privacy

Wishlist apps may collect product selections linked to customer emails or accounts. Confirm:

• How data is stored and who owns it
• Whether data is exportable or locked behind the vendor
• Compliance with GDPR and other data protection frameworks

Neither app’s brief descriptions included privacy certifications or export promises in the provided data. Merchants should request terms that clarify data ownership, export tools, and data deletion processes.

Scalability and Long-Term Costs

Wishlist features may seem inexpensive initially, but costs can grow with traffic and engagement.

• SWishlist: Pricing is very predictable—free entry, modest mid-tier, and clear unlimited top tier at $12/month.
• Sirius Wish: Pricing scales with sessions and wishlist actions and becomes materially more expensive at higher tiers.

Merchants should forecast wishlist actions per month and map them to plans to estimate monthly costs at scale, while factoring in potential overage rules. Also consider the operational cost of managing multiple vendors as app count grows.

Public Proof and Vendor Credibility

Vendor credibility matters for long-term stability.

• SWishlist: 106 reviews, 4.9 rating — strong social proof that many merchants have used and rated the app positively.
• Sirius Wish: 0 reviews, 0 rating — absence of reviews is a red flag for many merchants because there is no visible merchant feedback. This could indicate a new app, private distribution, or limited adoption.

Practical takeaway: For mission-critical UX components, prefer apps with public merchant reviews and documented case studies unless the new vendor can provide reference stores and technical documentation.

Pros and Cons Summary

SWishlist: Simple Wishlist

• Pros:
  • Excellent public rating (4.9) across 106 reviews.
  • Low-cost tiers and a $12/month unlimited additions plan.
  • Clear multi-language support and theme setup.
  • API support is indicated.
  • Published support SLAs.
• Cons:
  • Wishlist-only solution, which means adding another app for loyalty, referrals, or reviews.
  • Advanced analytics available only on premium plan.

Sirius Wish

• Pros:
  • Usage-focused pricing may suit traffic-driven stores.
  • Appears to emphasize insights around customer preferences.
• Cons:
  • No public reviews in app store data provided.
  • Integration and support details not visible—needs merchant verification.

Who Each App Is Best For

• Best fit for SWishlist: Merchants who want a low-risk, low-cost wishlist that supports multiple languages, providing predictable limits and simple setup. Good for stores that value quick support and a high degree of localization.
• Best fit for Sirius Wish: Merchants who prefer a sessions- and action-based pricing model and are comfortable validating integration and support before installing. Potentially suited for traffic-heavy stores that track session volumes and want tiered capacity.

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

Adding a single-purpose wishlist app can be the right tactical choice, but the strategic reality is that merchants quickly accumulate multiple single-purpose tools: a wishlist, a loyalty app, a reviews app, and a referral app. This creates "app fatigue": more admin overhead, overlapping features, higher combined monthly cost, multiple points of failure, and fragmented customer data.

Merchants seeking to reduce complexity while driving retention outcomes should evaluate integrated platforms that consolidate complementary retention features. Growave’s philosophy—More Growth, Less Stack—illustrates this approach: combine loyalty, referrals, reviews, wishlists, and VIP tiers into a single retention stack so merchants can focus on outcomes, not maintenance.

Important integrated outcomes to consider:

• Unified customer profiles that map wishlist activity to loyalty points, referral conversions, and review authorship.
• Fewer vendor contracts and a single support channel for interdependent features.
• Easier cross-feature campaigns: reward customers for wishlist actions, incentivize reviews with loyalty points, or trigger referral offers from wishlist shares.

Growave bundles these capabilities. Merchants can see how an integrated stack simplifies operations and amplifies lifetime value by centralizing retention features rather than adding point solutions.

• For merchants who want to consolidate retention features and understand pricing in one place, consider how to consolidate retention features into a single investment instead of paying for separate wishlist, review, and loyalty apps.
• To add Growave to a Shopify store with the convenience of the App Store, the fastest route is to install from the App Store.

Growave’s integrated feature set (how it reduces app sprawl)

Growave combines several tools that frequently exist in separate apps. This consolidation addresses the most common causes of app fatigue.

• Wishlist (part of a retention suite)
  • Wishlist behavior becomes a signal that can be leveraged across other retention tools.
• Loyalty and Rewards
  • Merchants can create programs that reward wishlist actions, purchases, and referrals.
  • See how merchants build loyalty and rewards that drive repeat purchases without wiring multiple apps.
• Reviews and User-Generated Content
  • Collect and display reviews and curated UGC to improve conversion.
  • Tools to collect and showcase authentic reviews tie into rewards and referral campaigns.
• Referrals and VIP Tiers
  • Built-in referral campaigns and VIP programs increase LTV by rewarding top customers.

Each of these components is interconnected. For example, a merchant can incentivize wishlist shares with loyalty points and then surface those shared products in reviews campaigns or referral landing pages. That kind of cross-feature orchestration is either impossible or expensive with disconnected single-purpose apps.

Integrations, scale, and enterprise fit

Growave supports enterprise and scaling merchants with integrations beyond the storefront—covering checkout, subscriptions, and customer support systems. For merchants on Shopify Plus or planning to scale, consolidated solutions reduce implementation complexity and ensure a consistent brand experience across channels.

• For merchants evaluating enterprise readiness, Growave offers solutions for high-growth Plus brands with advanced customization and dedicated support.
• To assess how other merchants use the platform, review customer stories from brands scaling retention for real-world context.

Growave’s platform is designed to reduce the number of apps and point solutions a merchant needs. That lowers total cost of ownership and the cognitive load of maintaining multiple vendor relationships.

Pricing transparency and decision-making

Compare the total monthly cost of running separate best-of-breed single-purpose apps against the cost of an integrated platform. When comparing, include:

• Direct app fees
• Implementation and maintenance time
• Duplicate features across multiple apps
• Data export and reconciliation costs
• The opportunity cost of not acting on consolidated insights

Growave publishes plan comparisons so merchants can model the total cost. For merchants who want to evaluate the bundled approach visually and compare plan features, review how to consolidate retention features in one place.

Support and onboarding — one vendor versus many

App fatigue increases support complexity. With multiple vendors:

• Time is spent coordinating fixes between developers.
• Bug investigations can become a blame game between apps.
• Onboarding each app takes additional time.

Consolidation reduces these operational frictions. Growave’s higher-tier plans include more hands-on onboarding and a dedicated manager for larger merchants, reducing implementation risk and accelerating time-to-value. Merchants that need a walkthrough can book a personalized demo to see how an integrated retention stack improves merchant workflows and buyer lifetime value.

When to choose a single-purpose app versus an all-in-one platform

• Opt for a wishlist-only app when:
  • Budget is extremely tight and the sole priority is enabling simple favorites.
  • The merchant wants to test demand on a small subset of items before investing in a broader retention strategy.
  • Quick installation and minimal configuration are required.
• Choose an integrated platform when:
  • Long-term retention and customer lifetime value are strategic priorities.
  • Merchants want to reduce monthly app count and eliminate duplicate features.
  • Cross-feature campaigns (reward wishlist actions, incentivize reviews) are planned.
  • There is a desire for consolidated analytics and fewer integration points.

Growave positions itself as the practical path to consolidation—merchants can compare bundled plans to determine which offers the best value by counting the features that would otherwise require separate subscriptions.

How an integrated approach affects merchant KPIs

Integration changes how metrics translate to business outcomes:

• Conversion rate: Reviews + wishlist cues + loyalty nudges often convert more effectively together than in isolation.
• Repeat purchase rate: Loyalty programs that reward meaningful actions (reviews, referrals, wishlist behaviors) increase repeat purchasing frequency.
• Average order value: VIP tiers and targeted rewards can nudge basket size up when combined with wishlist-driven product recommendations.

Merchants that measure and act on consolidated signals tend to see compounding returns from coordinated retention strategies.

Implementation Checklist: What Merchants Should Ask Before Installing Any Wishlist App

When evaluating either SWishlist or Sirius Wish, and before considering an integrated alternative, run through this checklist:

• Will wishlist items persist across devices and customer accounts?
• Does the app provide webhooks or API endpoints for wishlist events?
• Are theme setup and customizations included or billed separately?
• What is the app’s support SLA and what channels are available?
• Are there public reviews or case studies from similar stores?
• How does the app impact site speed and what performance optimizations are included?
• How are data portability and privacy handled? Can wishlist data be exported?
• If usage limits are exceeded, how is overage handled?
• How easy is it to extend wishlist events into email or automation workflows?

Answering these questions will help merchants choose the right technical and commercial fit.

Conclusion

For merchants choosing between SWishlist: Simple Wishlist and Sirius Wish, the decision comes down to priorities. SWishlist is an excellent choice for merchants who need a simple, focused, and low-cost wishlist with strong localization and transparent support SLAs—backed by strong social proof (106 reviews, 4.9 rating). Sirius Wish presents a session- and action-oriented pricing model that can be appealing for high-traffic merchants, but the lack of visible public reviews and integration details requires careful validation before adoption.

Beyond choosing between two wishlist specialists, merchants should consider whether a single-purpose app meets long-term retention goals. App fatigue—multiple subscriptions, fragmented data, and duplicate feature overhead—can erode margins and slow growth. An integrated retention platform removes those frictions by centralizing wishlists, loyalty, referrals, reviews, and VIP tiers into one suite. Merchants who want to reduce tool sprawl and focus on retention outcomes can compare bundled options and pricing to see the total value of consolidation and how it aligns with growth goals.

FAQ

How do SWishlist and Sirius Wish differ in terms of merchant adoption and trust signals?

SWishlist shows established merchant adoption with 106 reviews and a 4.9 rating, which suggests solid product-market fit and reliable vendor support. Sirius Wish has no visible reviews in the provided data, which increases due diligence requirements. Merchants should request references or demo stores from newer or less-reviewed apps.

Which app offers better value for merchants who need multilingual support?

SWishlist explicitly lists multi-language support across plans (2 languages on Free, 7 on Basic, 20 on Premium) and includes free theme setup, making it the stronger choice for merchants with multilingual storefronts. Sirius Wish’s public description does not emphasize language support.

How does an all-in-one platform compare to specialized wishlist apps?

An all-in-one platform trades the simplicity of a single feature for the strategic benefits of consolidation: unified customer data, coordinated retention campaigns, fewer vendor relationships, and often better long-term value. If retention—repeat purchases, LTV, and cross-feature campaigns—is a priority, integrated solutions typically outperform a patchwork of single-purpose apps.

If a merchant chooses Sirius Wish for its session-based pricing, what should they confirm first?

Confirm integration capabilities (API, webhooks), support SLAs, theme compatibility, and overage policies. Because Sirius Wish’s pricing is tied to sessions and actions, ensure the vendor provides clear scaling behavior and that the app can export or surface wishlist events for marketing automation.
