Pler - Domain Probe & Cloudflare Checker

Pler is a simple yet powerful Python script to check whether a domain is using Cloudflare.
It is useful for bug bounty hunters, pentesters, or OSINT purposes, as it can filter results according to your needs.

✨ Features

• 🚀 Multi-threading → fast domain checks.
• 🌐 IPv4 & IPv6 support.
• 🎯 Result filtering → only IP, only domain, or domain + IP.
• ☁️ Cloudflare detection → quickly identify domains behind Cloudflare.
• ❓ Unknown mode → show domains that cannot be resolved.
• 📄 Save output to file for later use.
