Pricing
CustomNosto does not publish fixed public pricing; it is quote-based and tailored per merchant via a demo request. Historically, Nosto started with a pay-on-performance model (charging only on conversions from recommendations), then moved to a fixed monthly license fee scaled to merchant revenue, and later introduced modular 'Build Your Own' plans letting merchants select and pay for specific products (recommendations, search, merchandising, A/B testing, etc.) rather than a single bundled tier. Enterprise features, professional services, and Huginn AI agent access are typically part of custom enterprise contracts. Merchants must contact Nosto's sales team or book a demo to receive a specific quote.
FreemiumKlevu uses custom, usage-based pricing scaling with domains, sessions, and SKU count, billed annually with no permanent free plan, though a 14-day free trial is available to test the platform. On Shopify, published starting prices include $449/month for the Recommendations module (500K impressions), $549/month for Category Merchandising, and $649/month for Site Search, with combined or larger-catalog plans ranging from $799 to $1,499+/month depending on traffic and product count. Third-party review sites also list a general starting price around $499/month per user for the base Klevu platform. Pricing for non-Shopify platforms, including Magento, BigCommerce, and custom storefronts, requires a fully custom quote from Klevu's sales team based on catalog size, traffic volume, and which modules (Search, Merchandising, Recommendations, Personalization, Klevu Moi) are needed. Enterprise customers with very large catalogs or complex multi-region requirements should expect pricing at the higher end of or above the published ranges.

Nosto Pros & Cons

Pros

  • Full-stack Commerce Experience Platform covering recommendations, search, merchandising, testing, and UGC in one system
  • Modular 'Build Your Own' pricing lets merchants pay only for the products they actually use
  • Huginn AI agent network adds genuinely new agentic capabilities beyond typical rules-based personalization
  • Strong enterprise track record: 1,500+ brands across 100+ countries with well-documented case study results
  • Native integrations with all major commerce platforms (Shopify Plus, Salesforce Commerce Cloud, Adobe Commerce, BigCommerce, Shopware)
  • Designed to have no negative impact on site speed, addressing a common concern with personalization tools

Cons

  • No public pricing — requires a demo and sales conversation to get a quote, which slows evaluation for smaller merchants
  • Pricing is based on merchant revenue, meaning costs scale up automatically as a store grows, which can surprise fast-growing brands
  • Enterprise-grade platform aimed at mid-market and larger retailers; likely overkill and cost-prohibitive for small independent stores
  • Full value requires clean, well-instrumented first-party data, so stores with messy product or customer data need setup work before seeing strong results
  • Deep feature set (personalization, search, merchandising, A/B testing, agentic AI) means a real learning curve for teams new to CXP-style tools

Klevu Pros & Cons

Pros

  • Semantic AI search genuinely understands vague and misspelled queries better than basic keyword search
  • Klevu Moi's conversational shopping assistant is a differentiated feature most search competitors don't yet offer
  • Strong, consistent review ratings: 4.8/5 on the Shopify App Store and 4.4/5 across broader platforms
  • Search Insights dashboard gives merchandising teams actionable data on zero-result searches and conversion gaps
  • Well-documented APIs and SDKs make integration straightforward across Shopify, Magento, and BigCommerce

Cons

  • Fully custom, quote-based pricing with no free tier, only a 14-day trial, making upfront budgeting difficult
  • Entry pricing around $449-$499/month puts it out of reach for very small stores or those just starting out
  • Now owned by Athos Commerce following its January 2025 acquisition, alongside Searchspring and Intelligent Reach, which may mean product direction shifts over time
  • Best value requires a large enough catalog and search volume to justify the premium price point
  • Non-Shopify platform pricing (Magento, BigCommerce, custom storefronts) requires a fully custom quote rather than published tiers
