Detect

How we detect every web technology — one per page

For each technology we can identify, here's the exact list of signals we look at, what they mean, how versioning works, and how to confirm the detection yourself in Chrome DevTools.

Web framework

Detect Next.js

Production-grade React framework from Vercel — the most-used meta-framework on the web.

Detect Nuxt

The Vue framework — SSR, file-based routing and module ecosystem on top of Vue 3.

JavaScript framework

Detect React

The JavaScript library for building user interfaces — the base most meta-frameworks build on.

Detect Vue.js

Progressive JavaScript framework — the most popular alternative to React, especially in Asia and Europe.

Detect Svelte

Compile-time JavaScript framework — no runtime VDOM, components compile to direct DOM operations.

CMS

Detect WordPress

The content management system that powers roughly 40% of the web.

E-commerce

Detect Shopify

Hosted e-commerce platform — the largest Shopify-store dataset on the web.

CSS framework

Detect Tailwind CSS

Utility-first CSS framework — the dominant CSS layer for React/Vue/Svelte apps.
