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.

We tested search at nearly thirty distributors. Here is what breaks.

In July 2026 we ran the same queries against the on-site search of nearly thirty North American electrical and industrial distributors. Four failure patterns stood out.

Some searches return nothing for one wrong letter. A handful of distributors — national names among them, on major commercial search platforms — return a zero-results page for a single transposed letter in "circuit breaker".
More often, the results quietly collapse. One catalog drops from 121 results to 2 on one mistyped letter; another from 79 to 14. No correction offered. The customer concludes the stock isn't there.
Specs get ignored. Search "circuit breaker 20A" and 15- and 30-amp units rank in the top three. One national distributor answers that query with over 50,000 items — and the same catalog returns nearly 100,000 for the misspelled version.
Descriptive queries rank the accessories. Ask for conduit by size and material and the couplings and connectors come back first. This was the weakest query everywhere, on every class of platform.

Buying a search vendor did not predict good search — some of the strongest catalogs we tested ran no commercial search product at all. Reproduce any of these on your own storefront in thirty seconds. Type a part number wrong. Read the full audit →

Dartfind vs Klevu, side by side.

	Dartfind	Klevu
Pricing	One-time license, owned outright	Subscription tiers, forever
What the merger means	Nothing — you own the binary	Migration to the new Athos platform ahead
Typo & intent handling	Built into the matching math, ships in the binary	NLP service in vendor cloud, active while subscribed
Spec queries	“20A”, “5W-30”, “3/4 inch” — the spec in the query ranks the results	Semantic model; spec precision depends on catalog data mapping
Hosting	Your server — on-premise or your own cloud	Vendor cloud only
Data location	Queries never leave your network	Query stream processed on vendor infrastructure
Long-term cost	Fixed. Grow 10x — no new bill	Recurring, scales with usage and tiers

What that looks like in practice.

A query typed the way real customers type — and the result list it lands on.

The letter “o” instead of a zero, no dashes, lowercase — and every result is the right part. Demo catalog shown; the same engine runs your data in the pilot.

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:

You want conversational, intent-level NLP. Klevu's language models handle phrasings like "warm jacket for hiking under $100" — interpreting intent rather than matching catalog fields. Dartfind is built for catalog queries: part numbers, product names, specs. If your shoppers write sentences, Klevu's approach fits that traffic better.
Personalization drives your conversion math. Per-visitor ranking and behavioral recommendations are platform features Athos is consolidating. Dartfind ranks against the catalog, not shopper profiles.
Small Shopify catalog, standard needs. A few thousand SKUs on a stock storefront is what app-based search subscriptions are made for. One-time-license economics favor real catalogs and real volume.

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.

Klevu alternative — questions people actually ask.

What did the distributor field test actually show?+

In our July 2026 field test of nearly thirty North American distributors, four failure patterns stood out. A handful of sites return zero results for one transposed letter in "circuit breaker". More return results that quietly collapse: 121 items to 2 on one mistyped letter, with no correction offered. Spec queries like "circuit breaker 20A" surface 15- and 30-amp units in the top three. And descriptive queries rank accessories above the product almost everywhere. Paying for a search vendor did not predict good search. Any of these takes thirty seconds to reproduce on your own storefront.

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.
