The practical differences
| Decision factor | Klevu | Nosto |
|---|---|---|
| Best for | mid-market and enterprise online merchants looking for unified site search, merchandising, and customer personalization | mid-sized and enterprise ecommerce brands wanting unified on-site search, category merchandising, and automated personalization |

| Pricing | At the review date in September 2026, public pricing is not listed on the official website. Prospective buyers must contact the sales team directly for quotes. | Nosto does not publish public plan pricing. Pricing is custom and requires booking a sales demo to discuss store requirements as of review date (2026-09-08). |
| Key difference | Now part of Athos Commerce, Klevu combines its product search and merchandising capabilities with Searchspring and Intelligent Reach to connect retail shoppers with products onsite and offsite. | Nosto unifies predictive recommendations, intent-driven semantic search, rule-based category merchandising, and shoppable UGC under a single commerce platform backed by Huginn AI agents. |
| Overall rank | #614 | #428 |
| Review verdict | Klevu is designed for online retailers seeking enterprise discovery, merchandising, and personalization tools backed by a broader retail software group. Smaller merchants needing standalone, self-serve software with transparent public pricing may prefer alternative storefront discovery plugins. | Nosto suits mid-market and enterprise ecommerce retailers seeking an all-in-one platform for site search, recommendation carousels, and visual merchandising. Smaller shops with simple inventory needs or restricted budgets may find its enterprise demo-only sales model unnecessary. |
