What it is
tld is a small, open-source toolkit for finding names whose domains you can actually buy:
- This website, for quick searches across your priority TLDs.
- A command-line tool that checks hundreds of candidates at once, generates name ideas from keywords, and outputs JSON, Markdown or CSV.
- A Claude Code plugin that brainstorms SEO-aware names, verifies them, screens them for existing products, and helps connect the chosen domain to Vercel or Supabase.
- A free hosted API, so the CLI and the plugin work without a registrar account.
Principles
- Honest prices. Every first-year price is shown next to its renewal price, minimum term and premium status.
- Results are never for sale. Affiliate links can pay for the hosting, but they never change which domains are shown or how they rank. Disclosure.
- Private by default. No accounts, no cookies, no analytics, and the domains you check aren't logged. Privacy.
- Open source. MIT-licensed, so you can read exactly how scoring works, self-host the API, or use your own Namecheap key.
How the score works
Each available domain gets a 0–100 score built from five parts: where its TLD sits in your priority list, the length of the name, readability (hyphens, digits and consonant clusters cost points), whether it contains your keywords, and its ongoing renewal cost. The notes next to each result explain the deductions. It's a tiebreaker, not an oracle: the best name is the one that fits your project.
Who makes it
tld is built and maintained by Ken Steele. It's an independent project and is not affiliated with or endorsed by Namecheap.
