A robust, privacy-focused, client-side tool for extracting domain names from unstructured text. Built with a focus on security, performance, and usability.
- Bulk Extraction: Paste massive blocks of messy text; the tool uses advanced Regex to identify valid domains while ignoring common file extensions (e.g., .jpg, .png, .exe).
- Smart Filtering:
- Word Filter: Filter by "Contains," "Starts with," or "Ends with."
- TLD Filter: Isolate specific extensions (e.g.,
.com,.org,.co.uk). - Length Control: Set minimum and maximum character limits.
- Pattern Matching: Include or exclude domains containing numbers or hyphens.
- Data Transformation:
- Group TLD-wise: Automatically categorize results by their extension.
- Extension Replacement: Mass-replace TLDs (e.g., change all results to
.net).
- Export Options: One-click Copy to Clipboard, or export to
.csv/.txt. - Responsive UI: Fully functional on desktop and mobile devices.
- Theming: Includes a toggle for Light (Outline) and Dark modes.
- Persistence: Automatically saves your filter settings preferences to LocalStorage.
- Client-Side Only: This tool runs entirely in your browser using Vanilla JavaScript. No data is ever sent to a server.
- Content Security Policy (CSP): Includes strict CSP headers to prevent XSS and script injection attacks.
- Sanitized Inputs: Protects against CSV injection and reverse tabnabbing on external links.
