Does Searchspring require Shopify Plus, or does it work on standard Shopify plans?

What do Athos and Shopify publish about a Plus requirement?

Neither Athos nor Shopify publishes a Plus requirement for Searchspring, now sold as Athos Commerce. The Athos app's Shopify listing is free to install and names no plan requirement (Athos listing, October 2026). Athos's Shopify page pitches control over an "Ecommerce Shopify or Shopify Plus Site" (Athos Commerce, October 2026). Athos's implementation guide compares three ways to build the integration and names no Shopify plan (Athos Commerce, October 2026).

On Shopify's side, the Plus plan page lists checkout, custom apps built with Shopify Functions, extra business-to-business (B2B) features and expansion stores, among other features. It names no search, filter or collection-sorting feature (Shopify Help Center, October 2026). So nothing in what Athos runs on a Shopify store waits on a Plus upgrade.

Which features does Shopify Plus actually gate?

Shopify Plus gates checkout apps, custom Functions apps, unlimited business-to-business (B2B) catalogs and expansion stores, among others, and none of them is search.

Plus costs $2,300 a month on a 3-year term or $2,500 on a 1-year term, and "more complex, higher volume businesses switch to a variable platform fee" (Shopify, October 2026). None of that buys search, so if someone tells you to upgrade to Plus to run a third-party search platform, ask which capability requires it; Athos's own pages name none. If the real question is Plus itself, the Advanced versus Plus answer at $1M a month runs the arithmetic.

Where does your Shopify plan still change the Athos decision?

Your Shopify plan changes the free baseline Athos has to beat, not whether Athos runs. Shopify's semantic search, one of its "AI-powered" search behaviors, needs Grow, Advanced or Plus and a store under 200,000 products, and it does not apply to predictive search (Shopify Help Center, October 2026). So a Basic store compares Athos with Shopify's search without semantic understanding, while a Grow store already has it.

Grow costs $105 a month against Basic's $39 billed monthly, or $79 against $29 billed yearly (Shopify, October 2026). So native semantic search adds $50 to $66 a month in plan fees, before Grow's lower card rates (Deploi arithmetic from the figures above). On Basic, try Grow's semantic search and measure your zero-result rate before an Athos demo, because Deploi's Athos versus native record reads zero-result queries and coarse filtering as the first strain on native search (October 2026). Deploi's answer on the catalog size where Athos's rule engine starts to win covers the other half of that test.

What gates a Searchspring purchase if Shopify Plus does not?

Three things gate buying Searchspring, now sold as Athos Commerce, on any Shopify plan: the quote, the implementation and your theme.

1. The quote. Athos lists Onsite, Offsite and Complete Discovery with "Request Pricing" and calls Onsite and Offsite "standalone annual plans" (Athos Commerce, October 2026). Klevu, Athos's other search app on Shopify, prices by search requests, category page views and recommendation impressions, not by Shopify plan (Klevu listing, October 2026). With no published Athos price, the sales conversation, not a feature flag, decides whether Athos sells to a store your size.
2. The implementation. Athos says "Implementation fees are custom-quoted based on project scope, complexity, and chosen implementation method" (Athos Commerce, October 2026), which ties the fee to the build, not to your Shopify plan. Deploi's answer on how long an Athos implementation takes covers the calendar.
3. Your theme. In an Athos-led build, "the Athos team builds, deploys, and maintains the integration," and "re-theming, re-platforming, or adding custom functionality may incur extra costs" (Athos Commerce, October 2026). So a later theme change, replatform or custom feature can add to the bill on any plan.

When should a merchant skip Searchspring on any plan?

A merchant should skip Searchspring, now sold as Athos Commerce, on any Shopify plan when the catalog is small, nobody will run the console or the only reason is an upgrade pitch.
