The README frames the tool as fast domain brainstorming with keyword permutations and availability filtering. The ChangeLog shows a rapid first public release cycle around 2025-05-31 and 2025-06-01, followed by v1.1.0 adding formatted output, RDAP as the primary domain-ownership source with whois and DNS fallbacks, and TLD presets. Later releases added file input, MCP support, and custom presets. ### Adoption history tldx is young compared with the other tools in this batch, but it maps neatly to modern terminal culture: indie hackers, technical founders, and developers checking many naming candidates quickly. The official blog explicitly names technical founders, indie hackers, and naming brainstorms as target users. The supplied package-manager facts show Homebrew, Nix, and winget availability. That package spread makes sense for a single-binary Go CLI intended for quick installation across developer laptops. ### How it is used Users pass one or more keywords and optionally choose prefixes, suffixes, TLDs, presets, regex generation, output format, input file or stdin, and only-available filtering. The README documents text, JSON, JSON stream, JSON array, CSV, and grouped output modes. For package nerds, tldx is interesting as a purpose-built network CLI that wraps RDAP, DNS, and whois behavior into a composable terminal workflow, with config limited to reusable TLD presets. ### Why package nerds care tldx is significant in a smaller modern-CLI sense: it packages a web-search-adjacent workflow into a local, scriptable binary with structured outputs and package-manager distribution. Its later MCP server support also shows how recent CLI tools increasingly expose both human terminal workflows and agent-facing command surfaces. ### Timeline - 2025-05-31: Official introduction published by the author. - 2025-06-01: ChangeLog lists 1.0.0. - 2025-06-05: ChangeLog lists v1.1.0 with RDAP primary source, output formatting, and TLD presets. - 2025-07-18: ChangeLog lists v1.3.0 adding file input. - 2026-05-24: ChangeLog lists v1.4.0 adding MCP support. - 2026-06-03: ChangeLog lists v1.5.0 adding custom presets. ### Related projects - RDAP is the primary availability-checking protocol documented in the README and ChangeLog. - DNS and whois are documented fallback mechanisms for domain ownership checks. - Model Context Protocol support is provided by the tldx mcp command in newer versions. ### Sources - - - - source_facts.package-manager for Homebrew, Nix, and winget packaging ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
