About this extension
Recon: SainiON is a passive information-gathering tool designed for security researchers, analysts, and bug bounty professionals.
This extension does not interact with live targets. Instead, it retrieves publicly archived data from trusted open sources, making it safe for compliance-friendly reconnaissance.

Features

Subdomain Enumeration (crt.sh)
Fetches Certificate Transparency logs and extracts unique common names to help identify potential subdomains.

Archived URL Discovery (Wayback Machine)
Opens one-click queries for:
• All subdomains
• Main domain
• Specific paths
• Sensitive file extensions (archived only)

Passive-Only Workflow
Every request is sent only to public data providers like crt.sh and archive.org.
No interaction with the target server takes place.

Modern Hacker-Style UI
Clean neon interface, equal button layout, and lightweight performance. Includes top-left branding and quick links.
