🕵️‍♂️ Grepr v2.0.0

Grepr is a blazing-fast, lightweight CLI tool designed for URL filtering and recon, built specifically for bug bounty hunters, penetration testers, and security researchers. Inspired by the simplicity of gf, Grepr adds targeted intelligence to filter URLs by file type, security templates, or super mode automation.

---

✨ New in v2.0.0

• 📂 Template System (GF-style): Use predefined security templates like sqli, xss, ssrf, s3-buckets, etc.
• 🚀 Embedded Defaults: Templates are now embedded in the binary. No more missing file errors!
• 🖥 Console-First Output: Results print to console by default (perfect for piping). Use -o only when you need to save to a file.
• 🧬 Dynamic Soora Mode: Automatically applies all security templates and core filters in one go.
• 🎨 Modern Banner: A professional new look for your terminal.

---

✨ Features

• 🎯 Filter by Filetype: Targeted matching for extensions like .js, .php, .aspx, etc. (Smart enough to handle query params!).
• 🔍 Regex Filtering: Filter lines using multiple regex patterns (from a list or file).
• 📋 Security Templates: predefined patterns for common vulnerabilities (SQLi, XSS, SSRF, IDOR, LFI, RCE, etc.).
• ⚡️ Soora Mode: The ultimate "Deep Scan" mode that runs every filter and template automatically.
• 🪶 Self-Contained: Go-embedded templates mean the tool works anywhere without extra setup.
• 📦 Clean Stats: Provides line counts and file sizes for all generated outputs.

🧠 Soora Super Mode

Soora is the ultimate automated engine. When enabled, it performs a comprehensive scan by applying:

1. Core Filters: Extracts all .js and .txt files.
2. Custom Configs: Applies patterns from config/extensions.txt and config/regex.txt.
3. Security Templates: Runs EVERY available template (sqli, xss, idor, lfi, rce, ssrf, ssti, redirect, s3-buckets, debug_logic).

🛠️ Usage

grepr -i all-urls.txt -s

📁 Output Files

Soora generates individual files for each category and merges them into:

📄 Final-Grepr.txt
