Redirect Mapper

Redirect Mapper, available here, is a Python tool that scans a list of URLs, domains, or IP addresses, follows their redirects using Selenium, and records the final destination along with additional metadata such as the resolved IP address and a SHA256 hash of the page body.

It is designed for large-scale redirect analysis, security research, and automation tasks.

Installation

pip install -r requirements.txt

Usage

python redirect_mapper.py <input_file> <output_file> [--proxy PROXY] [--num N] [--insecure]

Arguments

CLI Argument	Description
<input_file>	Path to a text file containing URLs/domains/IPs (one per line)
<output_file>	Path to the CSV file where results will be saved
--proxy	Optional HTTP proxy (example: http://127.0.0.1:8080)
--num	Number of worker processes (default: number of CPU cores)
--insecure	Accept insecure SSL certificates and bypass HTTPS errors

Input file (input.txt)

http://www.example.com/
google.com
104.18.26.120

Output CSV (output.csv)

Example

python redirect_mapper.py input.txt results.csv

Using a proxy:

python redirect_mapper.py input.txt results.csv --proxy http://127.0.0.1:8080

Running with multiple workers and accepting insecure certificates:

python redirect_mapper.py input.txt results.csv --num 8 --insecure
