Smart Wishlist vs. Sirius Wish: An In-Depth Comparison

Introduction

Choosing the right wishlist app is one of the small decisions that can have outsized effects on retention, average order value, and long-term customer value. Shopify merchants face dozens of wishlist options, and the wrong pick can mean extra monthly fees, fragile theme code, or a feature gap that blocks a growth tactic.

Short answer: Smart Wishlist is a focused, lightweight wishlist with a low monthly price and simple setup, while Sirius Wish offers tiered usage limits with a free entry plan but currently lacks public reviews and visible traction. For merchants who need more than a single-purpose wishlist and want to reduce tool sprawl, an integrated retention platform is often better value for money than picking separate one-off apps.

This article provides a feature-by-feature, data-driven comparison of Smart Wishlist (Webmarked) and Sirius Wish (Sirius Boost LTD.). The aim is to give merchants a clear sense of each app’s strengths, limitations, and best-fit use cases, and then show how a single integrated retention platform can eliminate common trade-offs that specialist wishlist apps impose.

Smart Wishlist vs. Sirius Wish: At a Glance

Deep Dive Comparison

This section compares Smart Wishlist and Sirius Wish across the dimensions that matter for merchant outcomes: features, pricing and value, integrations, implementation & performance, analytics & reporting, user experience, support & reliability, and compliance.

Features

Core Wishlist Capabilities

Smart Wishlist positions itself as a modern wishlist solution designed for one-click saving, with a strong emphasis on guest use (no login required) and shareable lists. Its public feature set highlights:

• Wishlist button on product, collection, search result, and cart pages
• Support for both guests and logged-in users
• Unlimited wishlists
• Javascript and REST APIs for advanced customizations
• Lightweight payload and “doesn't break your theme upon uninstall”

These features make the app appealing for merchants looking for a low-friction way to let visitors save items and share lists with friends or between devices.

Sirius Wish claims a robust wishlist experience focused on curated lists and reducing cart abandonment. Public claims include:

• Create and manage personalized wish lists
• Cohesive store integration
• Reduce cart abandonment by saving products for later

Sirius Wish’s public information is lighter on implementation specifics. The feature bullets are standard wishlist capabilities but lack explicit mentions of guest usage, APIs, or uninstall safety. The app uses a session-and-action quota model across plans, which implies the app tracks interactions and needs to limit usage for performance or pricing reasons.

Key takeaways for features:

• Smart Wishlist emphasizes one-click, guest-friendly behavior and technical hygiene (lightweight payload, APIs).
• Sirius Wish emphasizes the value of wishlists for engagement but is less transparent about developer tools and uninstall behavior.

Advanced Marketing & Growth Features

Smart Wishlist focuses narrowly on wishlist functionality. It does not advertise built-in loyalty, referral, or review functionality. For merchants, that means additional apps are needed to build rewards programs, collect social proof, or run referral incentives tied to wishlist activity.

Sirius Wish similarly markets wishlist-focused value, including insights into preferences, but does not claim additional retention features like loyalty or referral mechanics.

Practical implication: both apps are purpose-built wishlist tools. Expect to add separate apps for loyalty, reviews, referrals, or VIP tiers if the merchant wants a broader retention strategy.

Customization & Developer Access

Smart Wishlist provides JavaScript and REST APIs. That’s a meaningful advantage for stores that require bespoke behavior — for example, syncing wishlists to a CRM, exposing wishlist events to email automations, or building cross-device continuity beyond basic share URLs.

Sirius Wish does not list APIs or developer hooks publicly. That could be adequate for stores that want a plug-and-play wishlist without customization, but it limits advanced integration options.

Pricing & Value

Pricing affects not just monthly cost but the long-term total cost of ownership and the flexibility to scale.

Smart Wishlist Pricing

• Standard: $4.99 / month

Smart Wishlist’s published price is simple and low. For merchants whose only wishlist requirement is basic saving and sharing, $4.99 per month is a clear value. The single lower-cost plan reduces complexity when evaluating monthly expenses.

Things to consider:

• A single low-cost plan is attractive, but hidden caps (if any) should be confirmed with the developer.
• Because Smart Wishlist is a specialist tool, adding other needs (loyalty, reviews, referrals) will add additional monthly app costs.

Sirius Wish Pricing

• Free: Free (6000 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)

Sirius Wish uses a usage-based pricing model that ties cost to sessions and wishlist actions. Advantages and drawbacks:

• Advantage: Free tier lets merchants test basic wishlist functionality with capped usage.
• Advantage: Clear scaling path with higher usage tiers.
• Drawback: Session/action quotas introduce complexity and potential overage risk; merchants must monitor usage to avoid unexpected limits.
• Drawback: Pricing may become less attractive for stores with high traffic or large catalogs compared with flat-rate options.

Value-for-money assessment:

• For stores with limited traffic and experimentation budgets, Sirius Wish’s free tier can be a low-stakes way to validate wishlist demand.
• For stable stores that want predictable monthly costs, Smart Wishlist’s flat low-fee approach may be simpler and better value for money.
• Important: neither app includes loyalty, referrals, or reviews, so the full retention stack cost will be higher if those features are needed via additional apps.

Integrations & Ecosystem

Integrations determine how wishlist events feed into email automations, CRM, customer support, and analytics.

Smart Wishlist lists integrations with SendGrid and ShareThis. It also advertises API access for custom integrations. These are practical signals:

• SendGrid integration helps with wishlist share emails or transactional communications.
• API access enables deeper connections with automation platforms such as Klaviyo or Omnisend (though direct, pre-built connectors are not listed).

Sirius Wish does not list third-party integrations publicly on the app listing. That lack of disclosed integrations makes it less clear how easily wishlist data can trigger automations or route to a merchant’s stack.

Integration implications:

• Smart Wishlist is more transparent and appears more developer-friendly.
• Sirius Wish may still have integration capabilities, but merchants should verify integration options before committing.

Implementation & Performance

Theme Compatibility & Uninstall Safety

Smart Wishlist explicitly claims a lightweight payload and that it "doesn't break your theme upon uninstall." That is important: apps that inject heavy JavaScript can slow pages or leave orphaned code when uninstalled.

Sirius Wish provides no public promises about payload size, theme safety, or uninstall behavior. Merchants must test it on a staging theme to confirm.

Speed & Front-End Impact

Portals that add wishlist buttons across product, collection, search, and cart pages can impact perceived site speed. Smart Wishlist’s emphasis on lightweight code implies a smaller performance footprint. Sirius Wish’s lack of messaging here leaves the merchant uncertain.

Recommendations for merchants evaluating both apps:

• Test each app on a staging environment and measure page load times and Lighthouse metrics.
• Check uninstall behavior by installing and uninstalling on a copy of the theme to ensure no residual code remains.

Analytics & Data

Data visibility determines whether wishlist usage can be turned into targeted email flows, product prioritization, or inventory planning.

Smart Wishlist offers APIs that can expose wishlist events to analytics systems. That suggests merchants can capture:

• Items saved per customer
• Share events and referral paths
• Movement from wishlist to cart (if linked via email or user session)

Sirius Wish mentions "valuable insights into customer preferences" generally, but does not clarify the depth or format of analytics (raw event exports, dashboard, or integration with BI tools).

Merchants focused on data-driven retargeting and personalization will prefer an app that provides easy exports or direct connectors to analytics services.

UX & Design

A wishlist’s user experience affects conversion and repeat visits.

Smart Wishlist highlights one-click saving and shareable lists. One-click behavior reduces friction, especially for mobile users. Guest support reduces barriers: when a visitor wants to save for later but doesn’t want to create an account, guest wishlists can keep them engaged.

Sirius Wish emphasizes personalization and curated lists. If the implementation is polished, curated lists can boost social sharing and discovery. However, without public reviews or demos, the actual polish is uncertain.

Design considerations:

• Look for consistent button styling across product and list pages.
• Confirm mobile flows: does saving, viewing, sharing, and converting a wishlist item work smoothly on small screens?
• If the merchant wants wishlists as marketing triggers, ensure the app includes or exposes clear conversion signals.

Support & Documentation

Support responsiveness and documentation quality are critical, particularly for merchants without in-house developers.

Smart Wishlist’s public listing shows 81 reviews and a 3.6 rating. The volume of feedback indicates a moderate user base; merchants can scan reviews for common support themes. A 3.6 rating suggests mixed experiences — likely a mix of successful installs and some support or feature gaps.

Sirius Wish shows 0 reviews and a 0 rating on the public listing. That absence of reviews creates uncertainty about support quality, responsiveness, and bug resolution cycles.

When choosing an app with limited public feedback, merchants should ask:

• What are the support hours and channels (email, live chat, phone)?
• Is there a public changelog or roadmap?
• Are developers accessible for custom integrations?

Security, Privacy, and Compliance

Wishlist apps typically capture product IDs and sometimes user emails. Handling these data safely and in compliance with privacy laws is essential.

Smart Wishlist’s support for guest lists and APIs requires merchants to confirm whether any personal data is stored offsite, how long wishlists persist, and whether the app supports data deletion requests.

Sirius Wish’s public materials do not state data retention or privacy practices. Merchants should request documentation on:

• Data storage location and encryption
• Privacy policy and GDPR/CCPA compliance
• Data export and deletion procedures

Reliability & Trust Signals

• Smart Wishlist: 81 reviews, 3.6 rating. The presence of many reviews is a trust signal; the score suggests some merchants had friction but many used it successfully.
• Sirius Wish: 0 reviews, 0 rating. No public social proof makes it harder to estimate real-world reliability.

Merchants buying into a mission-critical front-end feature (like wishlisting) should prefer apps with evidence of ongoing maintenance and public feedback.

Comparative Pros & Cons

Below are concise pros and cons to make the trade-offs clearer.

Smart Wishlist — Pros

• Low, flat monthly price ($4.99).
• One-click saving and guest support reduce friction for customers.
• Shareable lists encourage social proof and referral-style sharing.
• JavaScript and REST APIs enable custom integrations.
• Claims to be lightweight and theme-safe on uninstall.

Smart Wishlist — Cons

• Narrow functionality (wishlist-only) — additional retention features require other apps.
• Mixed reviews (3.6) suggest inconsistent experiences across stores.
• Only a single plan publicly listed; pricing transparency for higher usage is limited.

Sirius Wish — Pros

• Free tier gives merchants a low-risk way to test wishlist features.
• Tiered pricing allows scaling with usage (sessions and wishlist actions).
• Pitches wishlist value for reducing cart abandonment and generating insights.

Sirius Wish — Cons

• No public integration list or API disclosure.
• Session/action quotas add complexity and may limit high-traffic stores.
• Feature descriptions are high-level; less technical transparency.

Use Cases & Recommendations

This section translates feature differences into practical recommendations for merchants with different goals.

Best for merchants who want a simple, low-cost wishlist

Smart Wishlist suits stores that want a fast, easy wishlist with minimal monthly cost and the ability to customize via APIs if needed. Ideal merchants include small catalogs, boutiques, and stores where one-click saving and shareable lists will meaningfully increase conversions.

Best for merchants experimenting on a tight budget

Sirius Wish’s free tier is attractive for merchants who want to test wishlist ideas without committing money. For early-stage stores or stores with limited traffic, the free plan can validate whether wishlists generate engagement.

Not a single app fit for merchants who want full retention stacks

Neither Smart Wishlist nor Sirius Wish provides loyalty, referrals, reviews, and VIP tiers as part of a single package. Merchants that need an integrated approach to retain customers, increase LTV, and manage promotions will find adding multiple apps creates complexity, duplicate billing, and integration overhead.

When to prefer an integrated retention platform

If a merchant plans to run loyalty programs, referrals, curated wishlists tied to rewards, and automate review collection and email flows, consolidating these capabilities into one platform can significantly reduce monthly app costs, cut development time, and improve cross-feature analytics.

Real-World Checklist Before Installing Either App

• Test on a staging theme to measure page load and uninstall behavior.
• Confirm whether guest wishlists persist across devices or only via share links.
• Ask about API access, webhooks, and how wishlist events can be exported.
• Verify support channels and expected response times.
• For Sirius Wish, monitor session and wishlist action usage to avoid reaching plan limits.
• For Smart Wishlist, confirm whether the $4.99 plan has hidden caps or if enterprise settings exist.

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

Multiple single-purpose apps can deliver narrow wins, but they often introduce hidden costs: duplicated tracking, inconsistent customer experiences, mounting subscription fees, and heavier maintenance. This problem is commonly called "app fatigue" — a point where the administrative and technical overhead of dozens of apps outstrips their incremental value.

An alternative is to consolidate retention and engagement tools into a single integrated platform that covers loyalty, referrals, social proof, wishlists, and VIP tiers. Growave’s positioning focuses on this exact outcome under the principle of "More Growth, Less Stack."

Why app fatigue matters

• Administrative overhead: Multiple invoices, different dashboards, and disparate customer data sources make day-to-day operations harder.
• Fragmented customer experience: When wishlists, loyalty points, and review prompts come from different vendors, the UX can feel inconsistent, reducing conversion rates.
• Integration gaps: Using separate apps often requires custom middleware or manual exports to connect wishlist events with email workflows or loyalty rules.
• Higher total cost: Even if individual apps are low-cost, the combined monthly expense of several specialist apps often exceeds the price of a unified platform that covers the same needs.

How Growave addresses these problems

Growave bundles wishlist functionality with additional retention tools so merchants can run more cohesive campaigns without stitching together multiple vendors.

• Growave includes wishlist functionality alongside loyalty and rewards, referrals, reviews & UGC, and VIP tiers. That means wishlist events can be natively tied to rewards and referral incentives without extra engineering.
• For merchants who want to build loyalty and rewards that drive repeat purchases, Growave offers customizable programs that integrate directly with wishlist behavior.
• Growave also lets merchants collect and showcase authentic reviews within the same platform, which streamlines review request flows after wishlist-to-purchase events.
• To evaluate fit, merchants can install Growave from the Shopify App Store or review subscription tiers to see how consolidation compares with a multi-app approach. Many merchants find it useful to consolidate retention features into a single plan to reduce complexity and centralize reporting.

Practical examples of consolidated benefits

• A wishlist save can automatically trigger a personalized email flow that includes a small rewards incentive after a set time — no separate Zapier or middleware required.
• Wishlists that sync with loyalty points allow merchants to run promotions like "Earn points when you add items to your wishlist" to incentivize retention behaviors.
• Review requests can be tied to purchases that originated from wishlist conversions, improving review relevance and conversion rates.

Technical and operational advantages

• Unified analytics: Having wishlist, loyalty, referral, and review data in one place enables clearer attribution and easier cohort analysis.
• Reduced integration burden: Native connectors (e.g., to email platforms and CRMs) mean fewer custom integrations and fewer moving parts to monitor.
• Simplified billing and vendor management: One vendor relationship reduces administrative time and vendor negotiation.

How Growave fits different merchant profiles

• For merchants who want enterprise-grade support and customization, Growave offers dedicated plans suitable for high-volume stores and Shopify Plus with checkout extensions and API/SDK capabilities. Merchants on enterprise paths can explore solutions for high-growth Plus brands and view customer examples to validate the fit.
• For smaller merchants, Growave’s entry-level plan can replace multiple single-purpose apps, delivering loyalty, wishlist, and reviews under one monthly cost — a way to get more growth with less stack.

Walkthrough of Growave features (contextual links)

• Loyalty & Rewards: Implement tiered programs, points-for-actions, and custom reward rules with minimal development. Merchants can build loyalty and rewards that drive repeat purchases and tie those rules to wishlist events for higher retention.
• Reviews & UGC: Automate review requests, collect UGC, and display social proof across product pages. Growave makes it easy to collect and showcase authentic reviews without relying on a separate app.
• Wishlist: Native wishlist functionality works together with loyalty and referral mechanics, making it possible to incentivize wishlist saves and convert saved items more reliably.
• Referrals & VIP Tiers: Run referral campaigns and reward advocates while creating VIP tiers that unlock exclusive perks — all in a single dashboard.
• For merchants evaluating the platform, a practical step is to install Growave from the Shopify App Store to review live feature behavior in the store environment and to compare costs with the existing app stack.
• To see real-world outcomes, merchants can read real customer stories that demonstrate how consolidation reduces friction and improves retention metrics.

Required interlinking compliance (practical placement)

• The platform’s pricing page allows merchants to compare monthly plans and identify whether consolidation is a better choice financially. Many merchants calculate their combined app spend and then use the consolidate retention features page to model savings.
• The Shopify App Store listing helps merchants test the app in a live environment: browsers can install Growave from the Shopify App Store to run a hands-on evaluation.
• To evaluate loyalty capabilities, merchants can review the loyalty and rewards that drive repeat purchases page.
• For review automation, the collect and showcase authentic reviews page explains how reviews and UGC integrate with other features.

Practical evaluation steps when considering consolidation

• Map current monthly spend for wishlist, reviews, loyalty, and referral apps and compare against the consolidated pricing tiers on Growave’s pricing page to evaluate ROI.
• Run a short pilot by installing Growave from the Shopify App Store and mapping one wishlist-to-email automation to measure conversion lift.
• Use customer case studies and feature docs to validate that Growave’s capabilities align with the merchant’s roadmap; view real customer stories for feature-specific examples.
• If a merchant needs a demo walk-through, they can book a personalized demo to see how wishlist functionality is linked with loyalty and reviews in practice.

When a Specialist App Still Makes Sense

Consolidation is powerful but not always necessary. There are situations where a specialist wishlist tool remains the right choice:

• Very small stores with a single wishlist need and tight margins may prefer Smart Wishlist’s $4.99/month flat fee.
• Experimental merchants who want to validate wishlist demand at near-zero cost may prefer Sirius Wish’s free tier.
• Stores with unusual technical requirements that demand a custom, headless implementation may prefer specialist apps that explicitly provide APIs and developer support; Smart Wishlist offers APIs for custom work.

Transition Checklist: Moving from Multiple Apps to a Consolidated Platform

For merchants considering moving wishlist functionality and other retention features into a single platform, the following checklist helps avoid migration pitfalls:

• Audit current app functionality and identify feature overlaps.
• Export wishlist data and user lists from current apps (confirm formats like CSV or JSON).
• Confirm data import paths and mapping rules into the consolidated platform.
• Test key automations in a staging store before enabling them in production.
• Monitor performance and customer KPIs (repeat purchase rate, LTV, email click-throughs) for the first 60 days post-migration.

Conclusion

For merchants choosing between Smart Wishlist and Sirius Wish, the decision comes down to simplicity versus a usage-tiered, experimental approach. Smart Wishlist (Webmarked) is a lightweight, low-cost tool that supports guest saving, shareable lists, and developer APIs; it has 81 reviews and a 3.6 rating that provide observable social proof. Sirius Wish (Sirius Boost LTD.) offers a free tier and tiered pricing based on sessions and wishlist actions, which is useful for early experiments, but it currently shows 0 reviews and 0 public rating — a signal to validate support and integration capabilities before production deployment.

If the merchant’s goal is purely to add basic wishlist functionality with a minimum budget and predictable billing, Smart Wishlist is a strong candidate. If the merchant wants to test wishlist demand with limited commitment and is willing to watch usage quotas, Sirius Wish’s free tier can be a sensible choice.

For merchants who want to stop juggling multiple single-purpose apps and instead build sustainable retention — combining wishlists with loyalty, referrals, and reviews in a single platform — consolidation is a better value-for-money approach. Growave’s "More Growth, Less Stack" philosophy addresses app fatigue by bundling wishlist, loyalty & rewards, referrals, reviews & UGC, and VIP tiers in one platform. Merchants can evaluate how consolidation compares to their current stack by viewing the options to consolidate retention features and by installing Growave to test features firsthand on Shopify: install Growave from the Shopify App Store.

FAQ

How do Smart Wishlist and Sirius Wish differ on pricing predictability?

Smart Wishlist provides a simple flat price ($4.99/month) that is easy to budget for. Sirius Wish uses session and wishlist-action quotas across multiple tiers (including a free tier), which reduces upfront cost but introduces variability as usage grows. Merchants that value predictable monthly expense typically prefer the flat-fee approach, while experimental stores may prefer the free or tiered options until usage stabilizes.

Which app is better for non-technical stores that want a plug-and-play wishlist?

Smart Wishlist markets itself as super-easy to set up with no coding required and emphasizes safe uninstall behavior. That makes it a strong fit for merchants without developer resources. Sirius Wish may also work plug-and-play, but its public materials are less explicit about ease of setup and uninstall safety. Merchants should validate installation steps and uninstall behavior in a test environment.

How important are APIs and integrations for wishlist functionality?

APIs and integrations matter when wishlist events should trigger email flows, loyalty points, or custom reporting. Smart Wishlist lists JavaScript and REST APIs, making it easier to connect wishlist behavior to a merchant’s marketing stack. Sirius Wish’s integration capabilities are not publicly clear, so any merchant with automation needs should confirm APIs and webhook availability before choosing it.

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

An all-in-one platform reduces administrative overhead, avoids duplicate functionality, and enables richer cross-feature automation (for example, awarding loyalty points for wishlist actions or automating review requests after wishlist-to-purchase conversions). Consolidation often produces better long-term ROI compared with separate specialist apps, especially when a merchant needs loyalty, referrals, reviews, and wishlists working together. Merchants considering consolidation can evaluate plans and expected savings on the consolidate retention features page and test the app by installing Growave on Shopify: install Growave from the Shopify App Store.
