Klevu alternative · One-time license · Self-hosted

The Klevu alternative where typo tolerance isn’t a subscription.

Klevu's pitch has always been AI-powered search that understands what shoppers mean. Dartfind gets to the same customer-facing result — typos, partial part numbers and glued words landing on the right product — through matching math that ships inside a binary you buy once and own. No NLP cloud, no per-tier AI features, no vendor to keep paying for the engine to keep understanding.

Built for distributors, wholesalers and e-commerce with large catalogs — from 10,000 to 100 million records.

Why teams go looking for a Klevu alternative.

The merger

Klevu is becoming Athos Commerce

Klevu merged with Searchspring and Intelligent Reach in 2025 under a private-equity owner, and the combined Athos platform is the future roadmap. New company, new priorities, migration ahead — renewal time is when people look around.

The model

Intelligence you rent

Klevu's NLP runs in Klevu's cloud, on Klevu's subscription. The moment you stop paying, your search stops understanding. Tolerance to how customers actually type shouldn't be a service — it should be a property of the engine you own.

The data

Your queries train someone else's cloud

Every search your customers type flows through vendor infrastructure. For B2B catalogs where queries reveal pricing interest, stock questions and customer intent, that stream is worth keeping inside your own walls.

When Klevu is still the right choice.

A comparison table where one column wins every row is an ad. Three cases where we’d tell you to stay put:

If your traffic is catalog queries — part numbers, SKUs, product names typed fast and badly — and you'd rather own the engine than rent the intelligence, that's the profile where Dartfind wins the comparison.

Switching is two connections.

A sync script feeds your catalog into the engine — from a database or a plain export — and keeps it updated on schedule. A query endpoint answers searches; your storefront calls it instead of Klevu. Works alongside Adobe Commerce, SAP Commerce, Oro, BigCommerce, Shopify or fully custom builds, because it sits behind an API rather than inside the platform. For most stacks this is days of work — and the free pilot skips integration entirely.

Those are numbers from a live deployment: an auto-parts retailer runs Dartfind as its counter and catalog search, fed with broken part numbers every day. Full case on the main page.

Don’t take the table’s word for it. Free pilot.

Send a catalog export — real or fake. Two days later you have a working search box in your infrastructure, next to your current Klevu setup. Type your customers’ worst queries at both. Then decide.

Klevu alternative — questions people actually ask.

What does the Athos Commerce merger mean for Klevu customers?+
Klevu merged with Searchspring and Intelligent Reach into Athos Commerce in 2025, and the combined platform is the stated future. Current features keep working, but roadmap, pricing and migration timing now belong to the new PE-backed company. A one-time license removes that class of uncertainty entirely: you own the binary, and your stack changes only when you decide.
Klevu's AI understands typos. How does Dartfind match that without AI?+
The customer-facing result is the same — a typo, a partial part number or a glued word lands on the right product. The mechanism differs: instead of an NLP service in a vendor cloud, tolerance is a property of Dartfind's matching math, computed inside the binary on your server. Nothing to subscribe to, nothing that stops working when a contract ends.
What can't it do that Klevu can?+
Honestly: conversational queries. "Something warm for hiking under $100" is intent interpretation, and that's Klevu's territory. Dartfind is built for catalog traffic — part numbers, product names, specs, typed fast and badly. Most distributor and B2B catalogs see almost nothing but that traffic; check your own query logs before deciding which problem you actually have.
What does switching involve?+
Two connections. A sync script feeds your catalog into the engine; a query endpoint answers searches, and your storefront — Magento, Shopify, BigCommerce, custom — calls it instead of the Klevu client. Days of work on most stacks. The free pilot skips integration: send an export, get a working search to compare on your own queries.
How does pricing compare?+
Klevu bills by subscription tier for as long as you want search to work. Dartfind is one payment — typically below a single year of a typical search stack — and afterwards growth in catalog or traffic creates no new bill. The license already covers it.
Where do our search queries go?+
Nowhere. The engine runs entirely inside your network, works with the internet cut off, and makes zero outbound connections. For B2B catalogs, the query stream — what customers search, when, how often — stays yours.
