A modern interface for live WHOIS & RDAP lookups.
Check domain availability across 1000+ TLDs with real-time WHOIS and RDAP lookups.
Built for developers, domain investors, and branding experts.
Avail is a domain availability checker designed to streamline domain research and branding workflows. It provides an efficient interface for checking domain availability across multiple top-level domains while delivering raw WHOIS and RDAP registration data through an intuitive, responsive UI.
Avail performs live WHOIS and RDAP lookups only.
- No domain searches are stored
- No WHOIS results are cached
- No user data is collected
- All history and preferences are stored locally in the browser
Avail is intentionally designed as a stateless, read-only inspection tool. Avail does not provide registration, pricing, valuation, or registrar integrations by design.
