Competitor price monitoring apps for Shopify, compared

A rival drops the price on the product you sell most, and you find out a week later from a customer email. Checking their store by hand worked when you watched two shops. It stops working as the list of products you care about grows.

The best competitor price monitoring app for a Shopify store depends on one question more than any other: do you want the app to change your own prices, or only tell you what changed? Prisync, Price2Spy and PriceKit can change prices on rules you set. CompeteTracker changes them when you click. Pick by that first, then by catalogue size and where you sell.

Updated 13 October 2026. Facts checked against the linked sources on 8 October 2026.

Which price monitoring app fits which Shopify store?

Each of the four fits a different store. Prisync fits a store that wants stock tracking and many competitors per product. Price2Spy fits a retailer on more than one platform. CompeteTracker fits a small store that wants a free start inside Shopify. PriceKit fits a seller across marketplaces who wants a free start and repricing rules with a price floor.

Every figure in this table comes from the vendor's own page, read on 8 October 2026.

How was this comparison checked?

On 8 October 2026, each tool's own pricing page, its homepage and, where one exists, its Shopify App Store listing were read in full. Plan names, prices and limits are copied as written. Where a vendor's pages disagree with each other, or leave a figure out, the table says so instead of picking one.

That turned up two things a quick roundup misses.

First, Prisync names the same plan at two prices. As of 8 October 2026, Professional is $99 per month on Prisync's own pricing page and $49 per month on its Shopify App Store listing. Both pages, prisync.com/pricing and the App Store listing, say up to 100 products and unlimited competitors. If you are comparing Prisync with a Shopify-only app, check which page your quote came from.

Second, Price2Spy's pricing page puts no dollar figure on its Starter or Basic plans, and lists Premium as "Price upon request". Its Shopify App Store listing does show prices, under different plan names: "Basic 2K" is $157.95 per month for up to 2,000 product URLs, and "Premium 10K" is $788.95 per month for up to 10,000. If you buy through Shopify, the listing is the page to quote from.

What does Prisync track, and what does it cost?

Prisync tracks competitor prices and stock, for unlimited competitors on every plan. As of 8 October 2026, its URL-based Professional plan costs $99 per month on its own site for up to 100 products, with prices updated three times a day. Its repricing engine starts on Premium.

Prisync's own page offers three ways to buy. "URL Based Competitor Monitoring" lets you "add competitor URLs one by one or simply in bulk per product." "Channel Based Competitor Monitoring" keeps "a particular focus on specific sales channels." "The Hybrid Model" combines the two. On prisync.com:

• URL-based: Professional $99/month (up to 100 products), Premium $199/month (up to 1000), Platinum $399/month (up to 5000).
• Channel-based: Professional $199/month, "Prices are Updated Daily".
• Hybrid: Professional $299/month, "Price Updates up to 3 Times a Day".

Every plan includes "Unlimited Competitors" and a trial: "14 days for free. No credit cards or contracts needed." Professional includes "Stock Availability Monitoring". The "Dynamic Pricing Engine", the part that changes your prices, is listed from Premium up.

The Shopify App Store listing reads differently: Professional $49/month for "Up to 100 Products / Variants" with "Price and Stock Updates 3x Day", Premium $199/month, Platinum $399/month. The listing has been up since June 16, 2015 and shows 4.9 out of 5 stars from 244 reviews. It describes the repricing side as "Set dynamic pricing rules based on product costs and competitive intelligence."

Best if you want to watch as many competitors per product as you like, care about their stock as well as their price, and expect to add repricing rules later.

What does Price2Spy track, and what does it cost?

Price2Spy tracks price, availability and promotions, and syncs with Shopify and six other platforms or feeds. As of 8 October 2026, its own pricing page shows no dollar price for Starter or Basic, and Premium is quoted on request. Its Shopify App Store listing starts at $157.95 per month, with a "14-day free trial".

The Price2Spy homepage names its integrations: "Shopify," "Magento2," "BigCommerce," "ShopWare 6.x," "WooCommerce," "Google Shopping feed," and "PrestaShop". It says it can "Track availability, promotions, ratings, and other AI-enhanced signals shaping buying decisions."

On the pricing page, the three plans are Starter, Basic and Premium. Starter covers "Up to 10 competitors". Premium allows "Up to 8 price checks per day", three user seats and API access. The page does not state a check frequency for Starter or Basic. Repricing is an optional module: "Automate the process of changing your prices. Use rules to create a pricing strategy of your own." Optional modules are priced separately. There is a "TRY FOR FREE" button, with no trial length stated.

The Price2Spy API lets you "manage products, URLs, and pricing data programmatically."

Best if you sell on Shopify and another platform, such as WooCommerce or Magento, and want one price tool for both, with an API your developer can use.

What does CompeteTracker track, and what does it cost?

CompeteTracker is a Shopify app that tracks competitor prices, suggests your own price, and updates your Shopify prices in one click with guardrails. As of 8 October 2026, it has a free plan for 3 competitors, Starter at $19.99/month for 10, and Pro at $49.99/month for 25.

Its Shopify App Store listing says it can "Track competitor prices automatically from any website with full pricing history" and "Update Shopify prices in one click with safety guardrails and audit trail." So a price change happens on a click, not on its own, and the listing pairs it with an audit trail.

Plans:

• Free: $0/month, 3 competitors monitored.
• Starter: $19.99/month, or $180/year, 10 competitors.
• Pro: $49.99/month, or $480/year, 25 competitors.

The listing does not say how often prices are checked. It also launched on January 26, 2026 and had zero reviews when read on 8 October 2026. That means there is no track record yet to read, which is worth knowing before you hand an app the power to change your prices.

Best if you run a small Shopify store, watch a few rivals, and want to try price tracking without paying, keeping a human click between a rival's move and yours.

What does PriceKit track, and what does it cost?

PriceKit tracks competitor prices across Shopify, Amazon, Etsy, Trendyol, Hepsiburada and custom stores, keeps a price history, and alerts you when the market moves. Its Shopify App Store listing adds that it "automatically updates your store's prices based on your custom rules". As of 8 October 2026, it has a free plan for 5 products, and paid plans from $19 to $249 a month.

PriceKit's pricing page lists:

• Free: $0/month, 5 products, 2 competitor URLs per product, 1 pricing rule, daily price checks. "Free forever · no credit card".
• Starter: $19/month, 50 products, 5 competitor URLs per product, 7 days price history, email and in-app alerts.
• Growth: $49/month, marked "Most popular", 250 products, 10 competitor URLs per product, 30 days price history.
• Business: $249/month, 1,000 products, unlimited competitor URLs, "2× daily price checks", 90 days price history.

Paid plans carry a "7-day free trial · cancel anytime". The PriceKit homepage lists "Do you change my prices automatically?" as a question, but no answer text was on the page when read on 8 October 2026. The Shopify App Store listing answers it: it names "Auto-repricing" and "Auto-matching" as features, and lets you "Set custom limits for price changes to secure profits" and "Define custom floor prices to never sell below your cost". The listing launched on January 9, 2026 and had zero reviews when read on 8 October 2026.

Best if you sell beyond Shopify, on Amazon or Etsy for example, and want repricing rules with a floor under them, starting on a free plan.

Do you want an app that changes your own prices?

Decide this before you compare prices. An app that only alerts you leaves every decision with you. An app that reprices you acts on a rival's move, sometimes before you have looked at it. The more of your catalogue you hand over, the more a rule has to be right.

Say you sell swimwear, and a rival marks down the one-piece that looks most like yours. An alert-only tool tells you, and you decide whether to follow, hold, or push a different style. A repricing rule might follow them down straight away. That is fine if their markdown is a clearance of the last sizes. It is not fine if they are starting a sale you would rather sit out.

The four tools sit at different points on this:

• One click, you approve: CompeteTracker, with guardrails and an audit trail.
• Rules that act for you: Prisync's "Dynamic Pricing Engine" from Premium, Price2Spy's separately priced repricing module, and PriceKit's "Auto-repricing", with floor prices you set.

Starting with alerts and adding automation later is easier than the reverse. Rules you have not watched in action are the risky ones.

Is a free plan or a manual check enough?

For some stores, yes. If you watch a handful of rivals and a few hero products, CompeteTracker's free plan (3 competitors) or PriceKit's free plan (5 products) may cover it. A weekly check by hand costs nothing if your rivals rarely change price.

Paying makes sense once the manual check stops happening, or once you need history to see a pattern, such as when a rival runs its sales. PriceKit keeps 7 to 90 days of history by plan, and CompeteTracker keeps "full pricing history". A tool that only shows today's price cannot answer "do they always cut prices in the last week of the month?"

Where does ecvision fit?

ecvision does not reprice your store, and it is not a dedicated price tracker. It reads a rival's prices alongside their catalogue, their Meta ads and their social accounts, in one workspace. It fits a founder who wants the whole picture of a rival, not a pricing robot.

On the plans, as of 8 October 2026, Starter is $20 a month for "Your store plus 5 rivals", "3 months of history" and "Catalogue, prices and social accounts", plus "Every ad they run on Meta"; Growth is $60 a month for "Your store plus 10 rivals" and "6 months of history". Free shows "No new reads of rivals".

How it handles prices:

• A product's price shows as the range the storefront published, from its lowest to its highest price, never a midpoint ecvision worked out.
• The catalogue summary has a "Median" and a "Range" column for each store, with a "Last full read" date at the right of the panel's head, above the table.
• In Settings, "Products and prices" is one row under the columns "Source", "Refreshes" and "Last full read". ecvision sets that schedule; you do not.

What it does not do matters as much. To "Does it touch my Shopify store?" ecvision's answer is "Never. Nothing to install, no Shopify Admin API, no orders, customers or revenue. ecvision reads only the pages any shopper sees." So it cannot change your prices. And to "Is it read every day?" the answer today is "Not yet." If you need a price check several times a day, Prisync or Price2Spy are built for that; ecvision is not, yet.

If a rival's price is one signal among many you want to read, see what ecvision reads and decide whether that fits better than a dedicated tool.

Checklist before you pick one

• Decide first: alerts only, one-click changes, or rules that reprice you.
• Count the products you would track, then match a plan's product limit.
• Check how often the plan you can afford actually checks prices, not the top plan.
• If you sell outside Shopify, check the tool covers those channels.
• Note the date on any price you read, including the ones here. Prisync's own site and its Shopify listing already disagree.
• For a new app with no reviews, start on a free plan before you let it change a price.
