Looking for the best alternative to Fast Simon?

Fast Simon has a deep search and merchandising stack. Semantic search and custom ranking controls, the parts that matter most at Plus scale, sit behind a higher tier. We include them on every plan.

Layers punches well above its weight. The platform is powerful and the SDK is easy to use and gives us the flexibility to build any search experience a merchant can imagine. The team's Shopify dev agency roots mean they actually get what dev partners need.

Layers was the first time we were able to create the kind of sort orders we were used to having in Salesforce. We saw a pretty immediate impact on conversion rate.

The difference is clear

You already paid for the AI

We include semantic search, behavioral ranking, and merchandising on every plan, so you never have to decide whether understanding your shoppers is worth an upgrade.

We build for Shopify, nothing else

We read your combined listings, metafields, and Markets catalogs as Shopify objects, not through a cross-platform data feed that flattens your store into a lowest-common-denominator format.

No synonym lists to maintain

We know "lbd" means little black dress because the model reads meaning. Nobody on your team needs a spreadsheet of what shoppers might type.

One index, every market

We serve every Shopify Market, currency, and language from a single index, so adding a region does not multiply what you operate.

Merchandising you can see

You pin, sequence, schedule, and preview against margin, inventory, and return data in one view, and you blend those metrics into ranking without precomputing anything.

Your bill stays predictable

We do not charge per session. A good Black Friday stays a good day for your business, not a billing event.

Save up to $200,000 annually

Switch to Layers and save up to 40% compared to other enterprise platforms, without losing a dollar in revenue.

Cost savings based on real-world onboarding data. Results vary by volume and features utilized.
