# Tech Stack

> Skill `tech-stack` on Faro. 0 sub-skills.

Analyzes any website and returns the technologies it is built with, grouped by category, such as the CMS, JavaScript framework, analytics, CDN, and server. Covers thousands of common web technologies with confidence scores.

**Category:** Web & Search  
**Tags:** tech-stack, technologies, cms, frameworks, analytics, competitive-analysis  
**Use when:** You want a per-site profile of the client-observable technologies one or more websites are built on.  
**Not for:** Finding companies that use a given technology, reading hidden backend databases or languages, historical adoption trends, or pages behind a login.  
**Returns:** information — Returns one profile per site, each listing the detected technologies (name, category, confidence), a grouped-by-category view, the web server, and whether the site responded successfully. Not a downloadable file.

## How to run
Skills run through one gateway with your Faro token. Hand it an `intent` in plain language; Faro routes to the right sub-skill, runs it, and bills per call. Raw tools are internal plumbing and are not directly callable.
