Onion URL Finder is a Python tool that generates random .onion V3 addresses and checks their accessibility through the Tor network. Supports parallel processing with configurable worker threads for faster checking, adjustable timeout values, and saves discovered accessible onion addresses to a file with thread-safe UTF-8 encoding. Useful for dark web research, OSINT investigations, and understanding Tor hidden service infrastructure. Requires a locally running Tor service.
