`GET https://api.deepinfo.com/v1/lookup/technology?url=https%3A%2F%2Freact.dev`

The technologies on react.dev: React, Next.js, Node.js and webpack on Vercel, next to four doubtful matches.

Example 3 of 6 · [Technology Lookup Examples](/reference/lookup/technology/examples/) · endpoint: [Technology](/reference/lookup/technology/)

Tags: `param` `url` · `value` `https://react.dev`

Asks for the technologies on `https://react.dev`.

Eleven technologies. Seven describe a modern JavaScript site: `React` (JavaScript frameworks), `Next.js` (in two categories, Web frameworks and Web servers), `Node.js`, `webpack` and `Vercel` as the web server, plus `Google Tag Manager` and `Google Analytics`. The other four, `RequireJS`, `Prototype`, `Google AdSense` and `Choices`, are reported with `confidence` 100, but they are unlikely on a Next.js site and none of them appears in the page's HTML: check such detections before relying on them.
