7 best Boost AI Search & Filter alternatives for Shopify (2026)

At a glance

Boost AI Search & Filter alternatives at a glance

Not every store has the same search problem. A large catalog may need better filtering and navigation, while another store may be more concerned with search relevance or helping shoppers discover related products.

The comparisons below cover the capabilities, pricing, and practical differences that matter when evaluating alternatives to Boost. Check which features are included in each plan rather than comparing app names alone.

How we picked

How we chose these Boost alternatives

All seven do Boost's core job, search and filters a shopper uses, and publish their prices on their own websites. After Sledge, we ordered them by fit. Boost is more than search, so we counted its other tools too: recommendations, bundles, pre-order, back-in-stock alerts by email or SMS, and a one-tap offer after checkout.

We moved the slider on Boost's pricing page on 23 October 2026. Your plan follows your average sales over the last three months, in tiers: Launch runs $29 to $159 a month up to $50,000, Convert $299 to $599 up to $400,000, and Accelerate starts at $699. Each $1,000 of that average past your tier's limit adds $2, and you cannot move down to a plan below the one your sales set. Say you are on Convert's first tier, $299 for up to $100,000, and your average reaches $120,000: you pay $40 on top of $299.

Alternative 1 · Sledge

Sledge: search and filters that also sell

A shopper finds the right product through search, then leaves with one item or none. Sledge works on that next click, placing offers where the shopper is already looking.

Search catches typos and your synonyms. Switch on “AI-Conversational Search”, the setting that reads a typed sentence, and “running shoes under $50” becomes a product type and a price filter. Filters cover tags, vendor, price, stock status, options and your custom product details, with color or image swatches, range sliders and a separate filter set per collection. A bundle card can sit in instant search, search results and collections, and the cart drawer carries an upsell.

Growth Intelligence turns on when you pick a paid plan. It reads your orders, searches and shopper behavior, names a fix, opens the offer form already filled in for you to review, then measures the result against your sales. Install Sledge on your store and the 14-day free trial runs filters, offers and search; AI search waits for a paid plan too.

Sledge shows no “did you mean” line on a misspelled search, and it has no wholesale catalog sync for B2B buyers. Pro indexes up to 10,000 products and Scale 200,000. Back in stock starts on Accelerate at $199, and Pro keeps 30 days of analytics where Boost's Launch keeps 90. Each plan also caps the sales from Sledge it covers each month, its Monthly Revenue Boost: $8,000 on Pro. Past that cap, Growth Intelligence pauses new suggestions until the month resets. If deep search alone is the job, Globo is the specialist pick.

Pro is $29.99 a month, Scale $89.99, Accelerate $199 and Ultimate $399. Sledge never edits your theme files.

Best for: you want search and filters plus the offers that sell after them, on one monthly plan.

Alternative 2 · Globo Smart Product Filter & Search

Globo: Boost's filter control on a smaller bill

You built a filter tree for each collection in Boost and want that control without a bill tied to sales. Globo matches the setup most closely, and its price follows your catalog size and Shopify plan instead.

Its Basic plan, from $14 a month for 500 products, lists unlimited custom filter trees, swatches with images or a color picker, unlimited search queries, unlimited merchandising campaigns in search, nine kinds of product recommendation, and Year/Make/Model search for parts catalogs. AI search arrives on Professional, from $29. On Shopify Plus the same two plans start at $69 and $99, yearly billing saves 17%, and each starts with a 14-day free trial.

Globo beats Sledge on entry price, spell check and Year/Make/Model search. The limit: the price climbs with your catalog, to $69 a month on Basic at 5,000 products. Basic keeps 90 days of analytics where Boost's top plan keeps 365, and the page lists no bundle offers, so those stay in another app.

Best for: you want Boost's filter depth at a price that ignores your sales.

Alternative 3 · Searchanise

Searchanise: search priced by catalog size

A small catalog rarely needs a big search bill. Searchanise prices by how many products you sell: free up to 25, then $19 a month up to 1,500.

You get instant search with autocorrect and suggestions, filters by size, color, discount and stock, recommendation blocks such as similar items and bestsellers, and reports on top searches and searches with no results. Voice search comes on every paid plan, and banners on search and collection pages start on Essential, $39 up to 7,500 products. Advanced is $89 up to 15,000 and Premium $349 up to 300,000, and a 14-day trial opens every feature.

Its free plan runs on a live store, where Sledge is free only on development stores. The limit: the price climbs with your catalog, and its plans list no bundle offers.

Best for: search and filters on a small catalog and a tight budget.

Alternative 4 · Doofinder

Doofinder: search, recommendations and quizzes on one bill

Boost also handles your product recommendations, so a new search bar alone leaves a gap. Doofinder sells search, recommendations and a quiz builder together, on every plan.

Basic is €61 a month, or €55 billed yearly, with up to 10,000 requests a month for each of the three. It carries AI search, voice search, synonyms, banners and product carousels on the homepage and product pages. Pro, at €186, adds suggestions as a shopper types. Advanced, at €436, adds search by photo, results personalized to each shopper, and Category Merchandising, which sets the filters and order on your collection pages. The free trial asks for no card.

Doofinder offers search by photo and quizzes, and Sledge has neither. The limit: prices are in euros and follow requests, which count each typed search and each indexing of your catalog. A yearly payment is not refundable.

Best for: you want search, recommendations and quizzes from one vendor, with a bill that follows search traffic.

Alternative 5 · Rapid Search

Rapid Search: every feature, priced by visits

When your sales swing but your traffic stays modest, a price tied to visits can cost less than one tied to sales. Rapid Search charges by monthly visits and puts every feature on every plan.

That covers semantic search, typo matching, synonyms, filters by price, color, size, tag or any custom attribute, pinning products to the top and hiding sold-out ones, a sticky search bar, and reports on what shoppers search for and cannot find. Plans start at $14 a month for 5,000 visits, stores under 5,000 products can use a free tier, and every plan includes live chat and a 14-day free trial.

The limit: if a traffic spike passes your plan's visits and you don't move up a plan, your store falls back to its built-in search until the next billing cycle. Its plans list no recommendations or bundles.

Best for: a small catalog with modest traffic that wants every search feature from day one.

Alternative 6 · Sparq

Sparq: deep collection filters from $19

The filter column on your collection pages may be the part of Boost your shoppers use every day. Sparq rebuilds that column on its cheapest plan, priced by products and use instead of sales.

Standard is $19 a month for 2,500 products and 30,000 impressions, and Sparq counts an impression each time a shopper uses its search or filters. It filters by variant, tag, review, discount and your custom product details, with color filters and a price slider, plus search as you type and reports on search revenue. Premium, at $59 for 7,500 products, adds automatic spell correction, banners, search redirects and out-of-stock handling. Enterprise is $299 for 50,000 products, and every plan starts with a 14-day free trial, no card needed.

Sparq starts below Sledge's $29.99, and going past your plan never switches it off: the extra is billed once. The limit: Standard has no spell correction, banners or redirects, and rule-based merchandising still reads “Coming Soon”.

Best for: you mainly need Boost's collection filters, on a small budget.

Alternative 7 · Shopify Search & Discovery

Shopify Search & Discovery: the free baseline

Before paying for any search app, check what Shopify gives you for nothing. Search & Discovery is Shopify's own free app, and it adds filters, boosts and recommendations to a theme that supports them.

Shopify's store search already matches typos and related words. The app adds up to 25 filters, product boosts that tie up to 10 search terms to a product, up to 10 related and 10 complementary products per product page, and a 30-day search summary, with longer ranges in Shopify's own reports. Here is how to set it up.

The limit: one set of filters serves the whole store, collections with more than 5,000 products show no filters, and it carries no bundle offers.

Best for: a small store testing whether better search is worth paying for.
