BuiltWith Technology Scraper

A Python script that scrapes BuiltWith.com pages for technology information used by websites, compiling a unique, sorted list of technologies.

Overview

This project is designed to quickly and easily compile the technologies a website uses by scraping its BuiltWith.com page. You can list multiple websites in an endpoints.txt file (each on a new line) to process them in batch. The script deduplicates the results so that only unique technologies are included in the final output.

Features

• Batch Processing: Add multiple website endpoints via endpoints.txt.
• Data Extraction: Scrapes technology data from BuiltWith.com pages.
• Deduplication: Outputs only unique technology names.
• Sorted Output: Produces a sorted list of technologies in output.txt.

Requirements

• Python 3.x
• requests
• BeautifulSoup4

Setup

1. Clone or Download the Repository

   git clone https://github.com/thejessicafelts/builtwith-scraper.git
   cd builtwith-scraper
   

2. Install Dependencies

   Use pip to install the necessary libraries:

   pip install requests beautifulsoup4
   

3. Prepare Endpoints File

   Create an endpoints.txt file in the project directory. Each line should contain the website endpoint (the part of the URL following http://builtwith.com/). For example:

   example1.com
   example2.com
   example3.com
   

Usage

Run the Python script:

python3 script.py

The script will:

• Read endpoints from endpoints.txt
• Construct full URLs by appending endpoints to the base URL http://builtwith.com/
• Scrape technology data from each page
• Deduplicate and sort the technology names
• Write the unique list to output.txt
