How to research a competitor's Shopify tech stack
"Tech stack" sounds like something only developers care about, but for a store it just means: which theme, which apps, which platform, and which design choices. Together they describe how a competitor operates and where it's putting its effort. This is a workflow you can repeat on any store in about ten minutes — and end with something you can hand to a client or teammate.
Step 1: Identify the theme and platform
Start at the foundation. Paste the store's URL into the detector and read the theme result first. Is it a free theme (Dawn, Refresh, Craft) or a paid one (Shrine PRO, Impulse, Prestige)? A paid theme signals a store that's invested in its storefront. No theme detected at all usually means a custom or headless build — a sign of a more technical, better-resourced operation.
If the scan comes back "not Shopify," that's still useful: the platform detector will tell you whether it's WooCommerce, BigCommerce, Wix or something else, which reshapes how you read everything that follows.
Step 2: Map the apps
Click "Check the apps on this store." This is the richest layer. Don't just note the names — look at where they cluster. A wall of review and social-proof apps means a store that competes on trust. A stack heavy with page builders and upsell tools means one focused on conversion and average order value. Subscription apps mean recurring revenue; dropshipping and print-on-demand tools mean no held inventory. The app stack is where the business model shows itself.
Start your research
Scan a competitor and map its whole stack.
Step 3: Note the design signals
Run the fonts-and-colours scan. This layer is easy to dismiss but it tells you who the store is for. A restrained two-colour palette with a clean sans-serif is aiming at a premium or professional shopper. A bright, high-contrast palette with a playful display font is chasing a younger, more impulse-driven audience. If your positioning is different from a competitor's, the design signals are often the clearest confirmation of why.
Step 4: Compare, don't just collect
One store in isolation is a data point. The insight comes from contrast. Put the competitor next to your own store — or next to another competitor — using the side-by-side comparison. Now the differences do the analytical work for you: the apps they run that you don't, the theme gap, the different design language. Comparison turns a pile of facts into a short list of decisions.
Collecting facts about one store is trivia. Comparing two is where the strategy appears.
Step 5: Package it so someone can act on it
Research nobody reads is wasted. When you find a comparison or scan worth keeping, use the "Copy share link" button — it produces a URL that re-runs the same result live whenever it's opened. Instead of pasting screenshots into an email, you send a link the client can click and explore themselves. For a team, one link beats a thread of attachments: everyone opens the same view and works from the same facts.
Because the link re-scans live, it also stays current. If the competitor changes its theme next month, the same link reflects the change — so a piece of research you shared doesn't quietly go stale.
Turning research into decisions
The whole workflow should end in a sentence, not a spreadsheet. Something like: "Our top three competitors all run subscriptions and custom landing pages; we run neither — those are our two experiments this quarter." That's the deliverable. The scans, the app lists, the comparison — they're the evidence. The decision is the point.
