nmavail 0.4.3

A powerful CLI tool to check name availability across domains and platforms

Nmavail

Nmavail is a powerful command-line tool designed to check the availability of names across multiple domains and platforms. Whether you are naming a startup, a new project, or an open-source library, Nmavail helps you secure your brand identity by verifying if a name is already taken.

Features

• Domain Availability: Checks popular TLDs (e.g., .com, .io, .dev, .ai) via WHOIS and DNS lookups
• Developer Platforms: Verifies username availability on GitHub and GitLab
• Package Registries: Checks if a name is available on PyPI, NPM, Crates.io, and Go Modules
• System Packages: Checks Homebrew, AUR, Debian/Ubuntu, and Alpine Linux
• Asynchronous & Fast: Uses async I/O to perform checks in parallel (~13 seconds total)
• Clean CLI Interface: Provides a beautiful, easy-to-read terminal output with smooth loading animations
• No Configuration Required: Works out of the box, no tokens or setup needed
