What is a tech stack detector?
A tool that inspects public website signals to infer CMS, builders, frameworks, hosting, and related technology—reported with evidence and confidence.

Website Tech Stack Detector
Find out what technology is behind a website. Scan for CMS platforms, page builders, JavaScript frameworks, hosting clues, ecommerce systems, AI development signals, and more.
A tech stack is the combination of tools that delivers the site you see—content system, visual builder, frontend framework, hosting, CDN, plugins, and increasingly AI-assisted workflows. Mapping that stack helps you research competitors, plan migrations, and validate technical claims.

What Is a Website Tech Stack?
In plain English, a tech stack is everything that makes a website work behind the design. It is not one product—it is a layer cake.
- CMS — system managing content (WordPress, Shopify, Webflow CMS)
- Builder — tool shaping layout (Elementor, Webflow Designer, Framer)
- Framework — JavaScript layer (React, Next.js, Vue, Nuxt)
- Hosting — where files run (Vercel, Netlify, shared hosting, platform-native)
- CDN — how assets are delivered globally
- Scripts and plugins — analytics, chat, commerce, forms
- Apps and integrations — storefront apps, marketing automation
- AI development tools — builders and assistants that accelerated the build
Why Tech Stack Detection Matters
Developers use stack detection to estimate maintenance complexity. Marketers use it to understand agility and integration options. Competitors use it to see how rivals ship campaigns. Buyers use it before acquisitions or vendor contracts. Agencies use it to benchmark proposals against reality.
When someone claims 'custom coded' or 'fully AI-built,' a tech stack scan is a fast reality check—always probabilistic, but far better than guessing from a screenshot.
What This Scanner Can Detect
Our library focuses on fingerprints that appear often enough in the wild to be useful—always with confidence labels.
- WordPress, Shopify, Wix, Webflow, Squarespace, Framer
- React, Next.js, Vue, Nuxt, Vite
- Elementor and major WordPress plugin paths
- WooCommerce ecommerce signals
- AI builder and AI-assisted deployment patterns
- Hosting and CDN headers where accessible
Evidence-Based Reporting
Each layer in the report includes evidence items you can audit: asset paths, meta tags, DOM attributes, script names, and hosting clues. Confidence scoring aggregates those items—high when multiple independent signals agree, lower when only weak traces appear.
From Curiosity to Competitive Research
Start with one URL and a question. End with a documented stack hypothesis you can test—view-source, network tab, additional pages, or a conversation with the site owner. The scanner is the first chapter, not the entire investigation.
Frequently asked questions
Can you detect every technology?
No. Obfuscated, headless, or heavily customized stacks may hide fingerprints. We report what we can support with evidence.
Can websites hide their tech stack?
Partially. Teams remove generator tags, proxy assets, or rebuild exports. Detection becomes harder—not impossible, but often lower confidence.
Does this detect WordPress plugins?
Often yes when plugins enqueue public assets with recognizable paths. Not every plugin exposes itself on every page.
Does this detect Shopify?
Yes—Shopify stores frequently reveal cdn.shopify.com assets, theme objects, and storefront patterns.
Does this detect AI website builders?
We look for AI-builder and AI-assisted patterns where public signals exist, framed probabilistically in the AI involvement estimate.
