Which TLDs are available?

The spread

The directory covers roughly three dozen extensions. The bulk of inventory is .com, followed by .org and .net. Beyond those, the depth is in .io, .co, .me, .app, .dev, .info, .ai and .tech, plus country extensions including .co.uk, .com.au, .us and .net.au. The long tail runs to things like .blog, .club, .tv and .xyz in smaller numbers.

Filtering by extension

TLD is a filter on the directory, and each extension also has its own page listing everything currently available under it. The filter only ever offers extensions that actually have listings behind them, with real counts, so an empty result isn't something you can click into.

Does the extension matter?

For search purposes, less than most people expect. A .com doesn't rank better than a .org for being a .com. What the extension does affect is what visitors expect and trust, and resale value, where .com still commands a premium. A country extension can help where your audience is local, and hurt where it isn't.

Weigh it against the domain's actual history rather than treating it as the deciding factor. A .org with a decade of archived activity and citations from real sources is a stronger asset than a thin .com.
