Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Shopify Competitor Monitor — Track Prices, Products, Apps & Tech Stack Track competitor Shopify stores for **app installs, theme switches, price changes, and new products** — automatically. Most Shopify monitors watch prices and stock only. This actor does that **and** fingerprints each store's **technology stack** — which of 30+ apps (Klaviyo, ReCharge, Yotpo, Gorgias…) and which theme a competitor runs, and the moment any of it changes. It's full **Shopify store intelligence**, not just a price tracker, for e-commerce teams, DTC brands, and agencies — at a fraction of the cost of Prisync ($99/mo) or Price2Spy ($58/mo). ### What makes this different from other Shopify price monitors? The Store has plenty of Shopify price/stock trackers. The gap they leave — and what this actor is built for — is **tech-stack and app-install intelligence**: - **Detect installed Shopify apps** — 30+ including Klaviyo, Yotpo, Judge.me, ReCharge, Bold, Loox, Gorgias, Privy, Omnisend, Smile.io, and more. Know a competitor's marketing/reviews/subscription stack — and get alerted the run they add or drop one. - **Identify Shopify themes** — see which theme each store runs (Dawn, Debut, Brooklyn, or custom) and catch redesigns/replatforms as they happen. - **Track the full catalog too** — price increases, price drops, new products, removed products, and stock changes across every variant, so you don't need a second actor for pricing. App and theme change-detection is the wedge pure price monitors don't cover — and it reaches a different buyer: agencies pitching app migrations, app vendors doing competitive intel, and DTC teams benchmarking their stack against rivals. ### How does Shopify competitor monitoring work? This actor reads publicly available data from any Shopify store and detects **what changed since your last run**. Schedule it daily or weekly to build a complete history of your competitors' moves: - **Track competitor prices on Shopify** — price increases, price drops, and discount patterns across every product variant - **Monitor new product launches** — know the moment a competitor adds or removes products from their catalog - **Detect installed Shopify apps** — 30+ apps fingerprinted from the storefront - **Identify Shopify themes** — the theme each store runs, and when it changes - **Track collection changes** — new/removed collections and shifts in product count per collection - **Extract store metadata** — country, currency, payment methods, product count, and plan details ### Shopify Competitor Monitor vs. price-only tools Free and cheap Shopify price trackers exist — but they stop at price and stock. None of them tell you a competitor just installed Klaviyo or replatformed their theme. | Feature | This Actor | Prisync / Price2Spy | Free Shopify price trackers | Manual | |---|---|---|---|---| | Cost for 100 stores/mo (weekly) | **~$26** | $58–99+/mo | $0 | Free (hours of work) | | Price & new-product tracking | ✅ | ✅ | ✅ | Manual | | **App / tech-stack detection** | ✅ **30+ apps** | ❌ | ❌ | ❌ | | **Theme / replatform detection** | ✅ | ❌ | ❌ | ❌ | | Snapshot diff (what changed) | ✅ | ✅ | Some | No | | Whole-catalog, every variant | ✅ | Limited by SKU tier | Limited | No | | No API key required | ✅ | N/A | Varies | N/A | ### What data can you extract from a Shopify store without an API key? Every Shopify store exposes public JSON endpoints that this actor reads — no authentication, no API key, no login required: - **Products** — title, handle, vendor, type, tags, all variants with price, SKU, and availability - **Collections** — name, type (custom or smart), product count - **Store info** — name, country, currency, description, payment methods - **Apps** — detected from script tags and meta tags in the storefront HTML - **Theme** — name and ID from the `Shopify.theme` JavaScript variable ### How to monitor a competitor's Shopify store 1. **Add store URLs** — paste one or more Shopify store URLs (e.g., `https://allbirds.com`, `https://gymshark.com`) 2. **Choose what to track** — products, collections, apps, theme — or all of them 3. **Run the actor** — the first run creates a baseline snapshot of each store 4. **Schedule recurring runs** — daily or weekly. Each run compares current state against the previous snapshot and reports every change 5. **Export results** — JSON, CSV, or push directly to Google Sheets, Slack, or your CRM via Apify integrations ### Pricing Pay-per-event pricing at **$0.065 per store analyzed**. No monthly subscription, no per-SKU tiers. | Stores monitored | Weekly schedule | Monthly cost | |---|---|---| | 10 stores | 4 runs/month | **$2.60** | | 50 stores | 4 runs/month | **$13.00** | | 100 stores | 4 runs/month | **$26.00** | Prisync charges $99/month for 100 products across just 5 competitors. This actor monitors 100 entire stores — every product, every variant, **plus their app stack and theme** — for $26/month. Free price trackers cost nothing but can't see the tech stack at all. Platform compute costs (typically $0.001–0.005 per store) are charged separately by Apify. ### Input example ```json { "storeUrls": [ "https://allbirds.com", "https://gymshark.com", "https://fashionnova.com" ], "includeProducts": true, "includeCollections": true, "detectApps": true, "detectTheme": true, "maxProductsPerStore": 0 } ```` ### Output example Each store produces one dataset item with a summary and detailed changes: ```json { "storeUrl": "https://allbirds.com", "storeName": "Allbirds", "scrapedAt": "2026-07-08T12:00:00Z", "isFirstRun": false, "summary": { "totalProducts": 292, "totalCollections": 45, "detectedApps": 12, "theme": "Dawn", "changesDetected": 7 }, "changes": { "newProducts": [{"id": 123, "title": "Tree Flyer 3", "handle": "tree-flyer-3"}], "removedProducts": [], "priceChanges": [{"productId": 456, "productTitle": "Tree Runner", "oldPrice": "98.00", "newPrice": "89.00"}], "stockChanges": [{"productId": 789, "productTitle": "Wool Runner", "variantTitle": "10", "wasAvailable": true, "isAvailable": false}], "newApps": ["Klaviyo"], "removedApps": [], "themeChanged": null } } ``` ### Use cases - **E-commerce agencies** — monitor client competitors automatically and deliver weekly intelligence reports covering pricing *and* tech-stack moves - **Shopify app & SaaS vendors** — track which competitor apps a target store installs or drops (churn/win signals for your own sales team) - **DTC brands** — track competitor pricing strategies, product launches, and technology stack changes - **Dropshippers** — find trending products early by watching what top stores add and remove - **Market researchers** — analyze Shopify app adoption trends across hundreds of stores - **Brand managers** — MAP compliance monitoring to detect unauthorized price drops by resellers ### FAQ **How do I monitor my competitors' prices on Shopify?** Add your competitor store URLs, run the actor once to create a baseline, then schedule weekly or daily runs. Each run reports exactly what changed — price increases, drops, new products, removed products, and more. **Can I see which apps a competitor's Shopify store uses?** Yes — that's a core differentiator. The actor fingerprints 30+ Shopify apps from the storefront and reports which are installed, plus flags newly added or removed apps between runs. It also identifies the store's theme. **How is this different from a Shopify price tracker?** Price trackers stop at price and stock. This actor adds app-install and theme detection with change alerts, so you catch a competitor adopting Klaviyo or replatforming their theme — signals pure price tools can't see. **How often should I check competitor prices on Shopify?** Weekly suits most categories; daily works better for fast-moving niches like fashion or electronics. The actor is lightweight enough to run hourly if needed. **Can you scrape product data from any Shopify store?** Any store built on Shopify that hasn't disabled its public JSON endpoints — the vast majority of the 4.8 million+ active Shopify stores. Non-Shopify URLs are automatically detected and skipped. **Is it legal to scrape Shopify store data?** This actor accesses only publicly available data through Shopify's standard JSON endpoints (`/products.json`, `/collections.json`, `/meta.json`). No authentication is bypassed and no private data is accessed. **How much does it cost compared to Prisync or Price2Spy?** $0.065 per store per run — about $26/month to monitor 100 stores weekly, versus Prisync's $99/month for 100 products across 5 competitors and Price2Spy's $57.95/month. For bulk monitoring it's 30–100× cheaper, and it adds tech-stack intelligence neither offers. **What Shopify apps can it detect?** Over 30 including Klaviyo, Yotpo, Judge.me, Privy, ReCharge, Bold, Loox, Stamped.io, Oberlo, DSers, PageFly, Shogun, Tidio, Gorgias, Omnisend, Smile.io, LoyaltyLion, Aftership, Hotjar, Zendesk, Intercom, Google Analytics, Meta Pixel, TikTok Pixel, and more. ### Limitations - Only works with Shopify-powered stores (non-Shopify URLs are automatically detected and skipped) - Password-protected stores cannot be accessed - Some stores disable the `/products.json` endpoint — product data will be unavailable for those, but metadata and app detection still work - App detection is fingerprint-based and may not catch every installed app, especially custom or niche ones - Stores behind aggressive Cloudflare protection may require proxy configuration # Actor input Schema ## `storeUrls` (type: `array`): List of Shopify store URLs to monitor (e.g., https://allbirds.com, https://gymshark.com) ## `includeProducts` (type: `boolean`): Extract the full product catalog with prices, variants, and availability ## `includeCollections` (type: `boolean`): Extract store collections and their product counts ## `detectApps` (type: `boolean`): Detect which Shopify apps are installed (Klaviyo, Yotpo, Judge.me, etc.) ## `detectTheme` (type: `boolean`): Identify which Shopify theme the store is using ## `maxProductsPerStore` (type: `integer`): Maximum number of products to scrape per store.
