🌐 domainctl – Fast Domain Discovery

Lightning-fast tool to find available domains, similar to domainr but faster and smarter. Part of the kb/tool-trinity|moul-tool-trinity.

Core Features

• Single command discovery: domainctl js.work → instant suggestions
• Smart TLD suggestions: Knows which TLDs support which features
• Semantic understanding: “jswork” → suggests js.work, javascript.work
• Registry intelligence: Combines suffixes, removes vowels, uses numbers
• Instant feedback: Sub-second responses via sqlite-cache|SQLite cache

Architecture

• Language: Go with focus on performance
• Database: Embedded SQLite for TLD metadata
• API: RESTful service on :8080, health check on :8081
• Cache strategy: Full TLD cache, selective domain check results
• Algorithms: Weighted scoring based on length, pronounceability, relevance

Domain Search Algorithm

• Normalize input: “foo bar” → “foobar”
• Generate variants: foo-bar, foob, fbr (vowel removal)
• Generate TLD permutations: fo.ob/ar, foo.bar, foobar.com
• Check cache for freshness before external lookups
• Perform parallel WHOIS/DNS lookups
• Sort results by availability and “semantic closeness”
• Smart heuristics: remove vowels, add/remove hyphens, split on valid ccTLDs

Commands

• domainctl check <domain> - Check single domain
• domainctl server - Run as API server
• domainctl js.work - Smart suggestions for “js.work”

Design Goals

• Speed first: Every millisecond counts
• Smart defaults: Work without configuration
• Developer-friendly: Clean CLI and API
• Extensible: Plugin system for custom algorithms
