Overview

Domain Checker is a Python-based tool designed to efficiently verify domain name availability across multiple top-level domains (TLDs). Unlike simple WHOIS-only checkers, this tool employs a dual verification strategy combining DNS record lookups with WHOIS database queries to provide highly accurate availability results.

The tool is particularly useful for:

• Brand managers checking name availability across multiple TLDs
• Developers looking for project domain names
• Domain investors researching available domain combinations
• Marketing teams validating brand name availability online

Features

Core Functionality

• Multi-domain checking: Verify multiple brand names simultaneously
• Multi-TLD support: Check availability across multiple top-level domains in a single run
• Dual verification: Combines DNS and WHOIS lookups for maximum accuracy
• Batch processing: Process domain lists from text files
• Flexible output: Console display with optional file export
• Filtered results: Display only available or only taken domains

Technical Features

• Fast execution: Efficient DNS queries minimize checking time
• Accurate results: Two-step verification reduces false positives
• Normalized input: Automatically handles spaces and special characters in brand names
• Deduplication: Removes duplicate entries automatically
• Error handling: Graceful handling of network timeouts and API failures
• Cross-platform: Works on Linux, macOS, and Windows
