EyeWitness is a Python tool used during security assessments to quickly take screenshots of a large number of websites in one pass. Instead of opening each URL manually in a browser, you give EyeWitness a list of addresses and it visits each one automatically, captures what the page looks like, and saves the results to a report. It also records each server's HTTP headers and checks whether the site appears to be running with default credentials that could be a security issue. The primary audience is penetration testers and security auditors who need to survey many web interfaces during an engagement. Common scenarios include scanning an IP range found during a network assessment, or reviewing web services exported from tools like Nmap or Nessus. EyeWitness accepts input as a plain text list of URLs, an Nmap XML file, or a Nessus XML file, so it fits naturally into an existing testing workflow. Under the hood, EyeWitness uses a headless Chromium browser to render pages, which means it handles modern JavaScript-heavy sites rather than just fetching raw HTML. The tool runs multiple pages in parallel using a thread count it calculates automatically based on the number of CPU cores available. It can also add delays between requests and route traffic through a proxy. Installation uses an isolated Python virtual environment so it does not interfere with other software on the system. Setup scripts are included for Windows, Linux, and macOS. After setup, you activate the virtual environment and run the tool from the command line. EyeWitness is open source and maintained by RedSiege. It is intended for authorized security testing only.
