The honest assessment
What Nosto does well and where it falls short
Nosto is a solid commerce experience platform. Its AI-powered recommendations, category merchandising, and A/B testing tools are well built, and its customer success team is consistently well rated. For B2C merchants on Shopify with well established behavioral histories and relatively simple product catalogs, Nosto delivers measurable lift.
The reasons merchants switch come from three specific friction points:
- Commission-based pricing that scales against you.Nosto’s pricing model charges a percentage of revenue attributed to its platform, typically 2.5% to 4% of attributed sales. As your revenue grows, so does your Nosto bill, regardless of whether Nosto’s contribution to that growth is marginal or central. For merchants with strong existing brand loyalty and high repeat purchase rates, a significant portion of Nosto’s attributed revenue would have been converted anyway.
- Integration complexity on non-Shopify platforms. Nosto’s Shopify integration is clean and widely used. On Adobe Commerce and Shopware, the integration is more complex, requiring technical teams to sync data, maintain compatibility across platform updates, and troubleshoot edge cases. The operational overhead is higher than the marketing materials suggest.
- The inference ceiling. Nosto personalizes by observing behavioral signals, what shoppers have browsed, clicked, and purchased, and using those signals to populate recommendation widgets. This works well for shoppers with predictable, consistent purchase patterns. It misses consistently for new visitors with no history to learn from, gift shoppers buying for someone else, and B2B buyers sourcing outside their usual categories. The algorithm gets smarter, but the ceiling of inference from behavior is fixed.
If you are switching from Nosto because the recommendations feel generic for too many of your shoppers, particularly B2B buyers, new visitors, or gift purchasers, a different recommendation engine will have the same ceiling. The constraint is the model, not the vendor.
A different model
What Webscale’s AI Shopping Assistant does instead
Webscale’s AI Shopping Assistant replaces the inference model with a dialogue model. Instead of observing what shoppers have done and guessing what they want, it creates a conversation where shoppers express what they actually need and receive an immediate, accurate, relevant response grounded in live first party data.
For merchants on Adobe Commerce and Magento specifically, this is meaningful in ways that a recommendation widget cannot replicate:
What the conversation model enables that inference cannot:
- Natural language discovery. A shopper who says “I need a gift for a cyclist who already has everything” gets relevant, curated results, not generic bestsellers from the cycling category. The assistant understands the use case, not just the category.
- Conversational context. ‘Show me options under $100’ builds on the prior query. ‘Does any come with free shipping?’ narrows the same set. The assistant never loses the thread.
- B2B account context. For B2B merchants on Adobe Commerce, the assistant has access to contract pricing, approved catalog access, and account purchase history through the Webscale CDP. A procurement buyer sees products they can actually buy at prices that actually apply to their account automatically, without requiring them to navigate catalog restrictions manually.
- Cold-start handling. New visitors and first time buyers, who Nosto’s algorithm handles poorly, are guided through natural language discovery. No behavioral history required. The assistant asks the right questions and surfaces relevant options from the first interaction.
- Order management in the same conversation. A shopper who asks about a product and then asks where their previous order is gets both answered in the same interaction. No support channel switch, no separate help center.

The Adobe Commerce and Magento angle
Why the advantage is most pronounced for Adobe Commerce and Magento merchants
Nosto’s Magento integration syncs your catalog to Nosto’s platform on a schedule and places recommendation widgets on your storefront through a module. The integration works. It also inherits all the constraints of a bolt on tool. It operates on a snapshot of your catalog, not live data. It has no access to your Magento customer accounts, contract pricing, or shared catalogs. Every platform update creates compatibility risk that your technical team has to manage.
Webscale manages the infrastructure layer for Adobe Commerce and Magento storefronts through its Agentic Commerce OS. The AI Shopping Assistant is not an integration. It is a native capability that runs inside the same managed environment as your storefront. This means:
- Live catalog access. Product data is current at the moment of the shopper’s query, with no sync lag
- Live inventory. The assistant knows what is actually in stock right now, including backorder status and lead times
- Adobe Commerce customer group context. B2B shared catalogs, customer specific pricing, and purchase approval rules are surfaced automatically
- No module maintenance. The assistant is managed by Webscale as part of the infrastructure, not by your technical team as a third party module
For B2B merchants on Adobe Commerce specifically, where catalog complexity, account specific pricing, and multi buyer approval workflows are the norm, the Webscale AI Shopping Assistant is the only option that handles all of this without requiring shoppers to navigate these constraints manually.
| The key distinction for Adobe Commerce B2B Nosto’s recommendation engine does not have access to Adobe Commerce customer groups, shared catalogs, or contract pricing. A B2B procurement buyer using a Nosto powered storefront sees recommendations based on their browsing behavior, not their account’s approved products or negotiated pricing. This creates personalization that is irrelevant at best and misleading at worst. |
When Nosto still makes sense
When you should stay with Nosto or choose a different alternative
Webscale is not the right answer for everyone evaluating Nosto alternatives. Here is when Nosto, or a similar recommendation platform, remains the better choice:
- You are on Shopify or BigCommerce. Webscale’s infrastructure native advantage is specific to Adobe Commerce, Magento, and Shopware. If your storefront runs on Shopify or BigCommerce, Webscale is not the right infrastructure partner for you.
- Your primary personalization need is multi channel, email, SMS, paid media, not on site discovery. Nosto’s platform includes email personalization and cross channel recommendations. Webscale’s AI Shopping Assistant is focused on the storefront experience. If cross channel orchestration is the priority, a platform like Bloomreach, Insider, or Klaviyo may be a better fit.
- Your shoppers have very predictable, consistent purchase patterns and the inference model works well. If your recommendation widget CTR is above 5% and your attach rate is growing, Nosto is doing its job. Do not switch a tool that is working.
- You need A/B testing infrastructure across your entire marketing stack. Nosto includes A/B testing for recommendations and personalization. Webscale’s AI Shopping Assistant does not include a standalone A/B testing framework.
Frequently asked questions
Frequently asked questions
Is Webscale a direct Nosto replacement?
A category upgrade, not a like for like replacement. Nosto is a recommendation and personalization platform that surfaces behavioral inference through widgets across your storefront. Webscale’s AI Shopping Assistant is a conversational product discovery layer that handles discovery, comparison, Q&A, and order management in a single conversation, grounded in live first party data, including B2B account context that Nosto cannot access. If you are switching from Nosto specifically because recommendations feel generic for too many shoppers, Webscale addresses the root cause. If you are switching because of cost or multi channel limitations, other platforms in the Nosto category may serve you better.
How does Webscale handle the commission pricing problem?
Webscale’s AI Shopping Assistant is included in the Agentic Commerce OS, a platform that is priced based on the merchant’s infrastructure and product tier, not on a percentage of attributed revenue. As your revenue grows, your Webscale cost does not automatically scale with it. This predictability is particularly meaningful for merchants whose strong brand loyalty and high repeat purchase rate inflate Nosto’s attributed revenue metrics.d revenue metrics.
Can Webscale handle Nosto’s recommendation widget use cases?
Yes, and more. Webscale’s AI Shopping Assistant handles product discovery, comparison, and guided recommendations in a conversational interface. It also handles order management, product Q&A, and personalization grounded in full behavioral history from the Webscale CDP. What it does not replicate is Nosto’s email recommendation widgets or pop up personalization. Those are part of Nosto’s multi-channel marketing layer. If email recommendations are a core requirement, you may want to run both: Webscale for on site conversational discovery and a platform like Klaviyo for email personalization.
Does Webscale work for both B2B and B2C merchants on Adobe Commerce?
Yes, with a meaningful advantage for B2B. For B2C Adobe Commerce merchants, Webscale provides conversational discovery grounded in live catalog and behavioral data. For B2B Adobe Commerce merchants, the advantage is more significant. The AI Shopping Assistant has access to Adobe Commerce customer groups, shared catalogs, contract pricing, and account purchase history through the Webscale CDP. B2B buyers see products they can actually purchase at prices that actually apply to their account without navigating catalog restrictions manually. This is the use case where the gap between Nosto’s inference model and Webscale’s infrastructure native approach is most visible.
How long does migration take?
For merchants already on Webscale’s managed infrastructure for Adobe Commerce or Magento, deploying the AI Shopping Assistant is an additive capability. No migration is required and it is typically live within a few weeks. For merchants not yet on Webscale infrastructure, a full platform onboarding is typically completed in 8 to 12 weeks. Webscale handles infrastructure migration, and the process does not require removing existing Nosto widgets before the AI Shopping Assistant goes live. Both can run in parallel during a transition period.
