Parallel is the best Boost Commerce alternative — an agentic experience platform that runs your search, merchandising, personalisation and CRO, and keeps optimising itself once it's set up.
You set the goals. Parallel does the tuning — continuously, as your catalogue and your shoppers change. No synonym lists to maintain. No filter tree caps. No merchandising rules to keep in sync with the season.
Here's what you get.
Unlimited filter trees, metafields and pins
No cap. Not a higher cap — none. Build the navigation your catalogue actually needs, with every attribute that matters, and stop designing around someone else's limit.
Personalisation that reads the session
A view doesn't always equal interest. Parallel reads what a shopper is doing right now and reorders what surfaces in milliseconds — based on genuine intent, not accumulated click noise. The shopper who arrives with a specific idea gets met where they are, not served last month's bestsellers.
Merchandising that runs itself
Collection order is predicted against the goal you actually care about — clear inventory, protect margin, lift conversion — and it moves as your data moves.
Upsells are stock-aware. When a recommended add-on sells out, the next best option slides in automatically. No dead recommendations. No Monday morning fixing them.
Agentic CRO instead of A/B tests
Stop running one test and shipping a winner that was right for last month's traffic. Parallel tests multiple variations across every stage of intent simultaneously and serves the most effective experience to each shopper in real time — hooking into any app block in the Shopify customizer, no code required.
You set the goal. The agents pursue it, continuously.
Eve: an agent that actually does things
Eve isn't a chatbot bolted onto a search index. In Eve Studio you build custom skills with no code — step-by-step instructions the agent follows — and connect MCP tools so it can take real action.
- Connect Gorgias: Eve collects the customer's details, understands the issue, files the ticket.
- Connect Notion: Eve checks your store information before it answers.
- Connect Firecrawl: build a skill that checks a competitor's live price, validates the claim, and resolves a price-match on the spot — instead of leaving it in a queue for two days.
Build the skill once. Eve runs it from then on.
Analytics that talk back
Parallel measures money, not impressions.
Every experience — predictive search, full search, chat, upsells, personalisation, collections, the recommendation agent — is attributed for the revenue and profit it influenced. Upsell attribution is pair-aware: it only counts when the viewed product and the upsell product are both purchased. No inflated credit.
You get profit per session, calculated from your own cost data. You get cohort economics — new visitors, themed browsers, high intent, repeat purchasers — each with their own PPS and purchase rate, so you can see which cohort is generating traffic and which is generating value.
And the agentic A/B view runs strategy dimensions in parallel — conversion, discount, inventory, product, profit — each with live variants ranked by profit per session and a winner declared.
On Evolve and above, you can just ask it.
"How many users are using chat on the product page?"
"Which cohort is bringing the most revenue?"
"What's my worst-performing collection strategy this week?"
No dashboard to learn. No export to pivot. No analyst to book. You ask the question you'd actually ask a colleague, in the words you'd actually use, and Eve answers from your live data.
That's the difference between analytics you look at and analytics you can interrogate — and it's how you find the thing you weren't looking for.
Analytics ship on every plan. Conversational analytics are Evolve and up.
The best features aren't paywalled
The core AI isn't reserved for the top tier. You get:
- AI-powered automated search that finds the right products without manual optimisation
- Product enrichment — AI key features and product summaries, generated for you
- Eve, the chat agent — the shopping and orchestration agent
- Automated merchandising — collections that reorder themselves against your goals
- Agentic upsells — Eve matches the perfect complementary products to every product in your store, and keeps them stock-aware
Agentic from day one. Not a roadmap item. Not an enterprise add-on. It's running the moment you install.
Pricing that tracks usage, not your revenue
Some search apps price by GMV — the more you sell, the more you pay, whether or not you're using any more of the product.
Parallel prices on usage: your catalogue size, your monthly sessions, and your chat volume. Grow your revenue and your bill doesn't move. Scale your traffic and it scales with you, proportionally, on the resources you're actually consuming.
Make the switch
If you're looking for a Boost Commerce alternative because the tuning never finishes — the alternative is a platform that tunes itself.
You configure Parallel once. It optimises from there.
