Introducing tld: names you can actually buy

Naming a project usually goes like this: you think of something good, type it into a registrar, and it's taken. You try a variation. Taken. You find one that's free on .io, then notice it renews at more than twice the first-year price. An hour later you have a spreadsheet and no name.

tld turns that hour into one search.

What it does

• Checks many names at once. Type a few names and tld checks each across your priority TLDs (.com, .ai, .dev, .io, .app and .co by default), with up to 50 domains per search.
• Shows the real cost. Every available domain shows its first-year and renewal price, plus premium status and minimum terms. For example, .ai requires two years upfront.
• Ranks results transparently. A 0–100 score combines TLD priority, length, readability, keyword relevance and renewal cost, with notes explaining every point.

Three ways to use it

1. This website

The search on the home page is the quickest way to check a handful of ideas.

2. The command line

The CLI is where tld shines for bigger searches. It generates candidates from keywords, checks hundreds of domains, and prints tables, Markdown, JSON or CSV:

$ uv tool install git+https://github.com/kensteele/tld
$ tld suggest "meal planner" fridge -t @seo
$ tld pricing com ai dev io app

It works immediately through this site's free hosted API. If you have a Namecheap account, tld config --username YOU switches it to your own key, with your prices and your limits.

3. Claude Code

The tld plugin gives Claude a full naming workflow:

1. Read your project and pull out its category keywords.
2. Brainstorm 30–50 names across several styles.
3. Verify them with tld in batches.
4. Web-search the best ones for existing products with the same name.
5. Present a ranked shortlist with registration links.

Ask it to "name my startup", or run /tld:domain-finder.

Principles

tld is MIT-licensed, it logs none of the domains you search for, and it uses no cookies or analytics. Registration links may use an affiliate link, which helps pay for the hosting, but they never change which domains are shown or how they're ranked. The disclosure explains exactly how that works and how to turn it off.

The code is on GitHub. Issues and ideas are welcome.
