How to choose

Which search method and catalog limit fit your store?

Start with the search method and indexed catalog limit. These fields show how a service handles product discovery and the amount of catalog information it can index.

Check the monthly query limit against expected shopper activity before choosing a paid plan.

Which merchandising and recommendation controls do you need?

Choose a service that lists the merchandising rules, product recommendations, and personalized results your storefront needs.

Compare these fields directly because product discovery can include search controls, suggested items, or results tailored to a shopper.

Which platforms and channels does it need to support?

Match the supported channels to your sales setup. Listings may cover web, API, Android, iOS, browser extensions, or self-hosted use.

A public API can help connect search to other software, while platform labels show where the product is intended to run.

Can you try it before paying?

Check the free-plan and free-trial marks before committing. Algolia, Capella Search, Fast Simon, and Amazon Personalize are examples with a free plan listed; Amazon Personalize and Doofinder list a free trial.

Paid pricing may be a published starting price or pricing on request. Bloomreach Discovery lists a starting price of $3,000 per month, while several listings request a quote.
