10 Best Shopify Product Filter Apps of 2026

Smart Product Filter & Search from Globo.io covers the filter types most Shopify stores ask for: price, size, color, tag, vendor, brand, collection and metafields, arranged in a filter tree that can differ by collection. The listing states an unlimited filter tree, smart search with unlimited queries, merchandising, spell check, Year/Make/Model search, real-time sync and 9 product recommendation types on the Basic plan, which starts at $14 a month for up to 500 active products and $19 for up to 1,000. PRO starts at $29 a month and adds AI-powered search, 180-day analytics, 40+ metafields and priority support. It can also display product variants as separate products, which helps fashion stores show each color in the grid. The free tier is limited to development, affiliate and trial stores, and Shopify Plus pricing starts at $69 a month. Its 4.9 rating from 2,419 reviews was the largest review base in this list when we checked.

Searchanise combines an instant search bar with collection filters, product labels and merchandising. Its listing describes unlimited out-of-the-box and custom filters, including tag filters and prefixes, plus personalized AI search and voice search. The Free plan covers development stores and stores with fewer than 25 products, with unlimited queries, advanced filters, real-time sync, AI personalization, analytics and merchandising, but it carries Searchanise branding. Basic costs $19 a month for up to 1,500 products and adds integrations, voice search and 30 minutes a month of visual modifications, and Essential costs $39 a month for up to 7,500 products with banners, an hour of custom client side modifications and priority email support. Shopify Plus stores have a separate Basic for Plus plan at $49 a month. All paid plans have a 14-day trial, and annual billing saves 15% to 16%. Stores with more than 1,500 products should compare its Essential plan with Smart Product Filter & Search and Findter.

Findter from FlintVerse is the low price option in this list, and its plans differ only by product count. Every plan lists unlimited queries and sessions, no branding, free theme customization, Auto Translate, unlimited filter sets, options and values, collection, metafield and sale filters, and partial, synonym and metafield search. Advanced options include Year/Make/Model filters and merged group values, and stores can hide or push out-of-stock products and use Search Booster to promote chosen items. The app is free for stores with fewer than 300 active products. Starter costs $9 a month for up to 3,000 active products, Growth $19 for up to 50,000 and Pro $59 for up to 100,000, each with a 14-day trial and 10% off for annual billing. The listing showed a 5.0 rating from 270 reviews, but the app only launched on August 29, 2025, and it does not list AI search. It suits stores that want many filters for little money.

Rapid Search replaces the theme's search icon with an always-visible AI search bar and adds product and collection filters by price, brand, color, size, metafields and tag. Its listing says it installs with no code and no theme edits and scales to more than 1 million products. Plans are metered by monthly sessions rather than catalog size: the Free plan includes 2,000 sessions, 1,000 products and all features with branding, Basic 1 costs $14 a month for 5,000 sessions, Basic 2 $27 for 12,000 and Basic 3 $39 for 25,000, each covering 100,000 products, unbranded, with email and chat support and a 14-day trial. The listing also advertised 30% off applied after install at check time. Merchandising tools let you pin, boost, demote or hide products, and synonyms can be managed by hand. Because the bill follows traffic, a store with a big catalog and steady traffic pays less here than on product based plans, while a high traffic store can outgrow Basic 3 quickly.

Boost AI Search & Filter goes beyond filters into a broader discovery suite. The Launch plan includes 5 custom filter trees, smart search and AI-powered search, 10 merchandising campaigns, recommendations and bundles, pre-order and back in stock features, a 90-day report and catalog sync up to 3 times a day. Pricing follows online GMV: Launch runs from $29 to $159 a month for stores under $50K monthly GMV, Convert from $299 to $599 for stores under $400K, and Accelerate from $699 to $1,499 for stores under $2.5M, which adds unlimited filter trees, AI personalized search and recommendations, B2B wholesale products and real-time sync. Filters work by tag, metafield and variant, and the app syncs multi-language, currency and Markets data across storefronts. Every plan has a 21-day trial. The listing showed a 4.7 rating from 1,627 reviews. Small stores pay more here than with Globo or Findter, but brands that would otherwise run separate recommendation and back in stock apps get them in one bill.

SoBooster's AI Search & Product Filter covers filters by tag, option, metafield and metaobject, predictive AI search with NLP and typo tolerance, keyword and semantic search, SKU search and Year/Make/Model. Every paid plan lists smart search with unlimited queries, unlimited filters by metafield and option, AI-powered search and synonyms, unlimited merchandising campaigns, real-time indexing and analytics. Merchandising can boost, bury or hide products by campaign or customer group, which is useful for B2B or member pricing. The catch is the item count: Starter costs $14.99 a month for 50 items and Essential $18.99 for 500, while the Shopify Plus plan costs $69.99 a month for 1,000 items with priority support. Variants as products and multilingual search and filter are listed as premium features at extra cost. The free tier is only for dormant, partner test and development stores. The listing showed a 4.7 rating from 436 reviews, and each paid plan has a 14-day trial.

Fast Simon, on the Shopify App Store since February 2014, positions itself as an AI merchandising layer for search, collections and recommendations. Its model weighs shopper intent with catalog, inventory, promotions and business rules, and merchants can still pin, boost and curate products, add badges and promo tiles and set guardrails for AI shopping agents. Search handles questions, typos, SKUs and images, and the app works headless through an API, a JS SDK and Hydrogen. The Free plan includes product filters and AI instant search but only 100 monthly sessions with daily sync. Starter costs $39.99 a month for 2,000 sessions and adds custom product filters, synonyms and hourly sync; Essential at $114.99 for 10,000 sessions adds optimized collection filters and real-time sync; Pro at $299.99 for 30,000 sessions adds merchandising rules, A/B tests and visual collection merchandising. Session based pricing makes it expensive for busy stores that only need filters.

Shopify Search & Discovery is the free baseline every store should try before paying for a filter app. Built by Shopify, it lets you customize the filters shoppers use to refine search and collection results across multiple categories, create synonym groups so product descriptions match the words shoppers type, boost chosen products in search results, and add related and complementary products on product pages. Analytics in the admin show how shoppers use search and discovery. The listing names more than 15 admin languages, including English, French, German, Japanese and Spanish. It costs nothing, but the feature list is shorter than the paid apps: there is no Year/Make/Model search, voice or image search, or per collection filter tree listed. Its 2.6 rating from 514 reviews at check time was the lowest in this list. Stores with simple catalogs can stop here, while stores that need metafield heavy filtering usually add a paid app.

Doofinder is an AI search and discovery platform that adds a conversational AI Assistant on top of search, filters and category merchandising. The listing says it is plug and play with no development required. Basic costs $61 a month and includes AI guided search, custom results, product recommendations and a quiz maker. Pro at $186 a month adds AI alerts, multi-index search, suggestions and dynamic recommendations, and Advanced at $436 adds 1:1 personalized results, AI-powered visual search, recommendation flows control and 365-day analytics. Enterprise pricing is custom. Its feature list includes multi-filter, custom filters, image search, voice search and typo tolerance. Each paid plan has a 15-day trial, and annual billing saves 10%. The listing showed a 4.7 rating from 757 reviews. At $61 a month to start, Doofinder costs more than four times the entry price of Globo or Rapid Search, so it fits stores that want the assistant and analytics, not only filters.

Algolia AI Search & Discovery brings Algolia's search engine to Shopify stores with filters, browse, merchandising and recommendations. Pricing is usage based and billed by Algolia separately from the Shopify invoice. The free tier includes 10K search requests, 50K records, 5K recommendation requests and 5K crawls a month. Grow includes 10K searches a month, then $0.50 per 1K, and 100K records, then $0.40 per 1K, with keyword search, browse, query suggestions, 10 rules per index and manual synonyms. Grow Plus charges $1.75 per 1K searches after 10K and adds 10K rules per index, AI synonyms and ranking, advanced personalization and query categorization. The enterprise tier adds NeuralSearch, real-time personalization, enterprise support plans and professional services. Support on the self-serve tiers is self-service only. The listing showed a 3.7 rating from 45 reviews, the second lowest here. It suits stores with a developer who can tune indexes and rules.
