What is TLD Notes?

TLD Notes is a field guide that catalogs how Top-Level Domains (TLDs) are used across industries, vibes, and eras — allowing you to explore the domain world through discovery.

Like an 18th-century naturalist observing and recording an unknown ecosystem, this site "observes" the domain world. Rather than "recommending" specific domains, it documents them as field notes — observational records.

About This Domain

The first choice for tldnotes.com was tldnotes.fyi. As an abbreviation for "For Your Information," .fyi seemed like the perfect name for an observational record site.

However, our Japanese domain registrar (Xserver Domain) didn't offer .fyi. After weighing whether to split management across international registrars, we settled on .com.

— The very moment we experienced the ".com gravity" that this site writes about.

About Snapshots

The domain world is constantly changing. Data on this site represents a "snapshot" at a specific point in time and may not reflect the latest conditions. Each page displays the date of research.

Use of AI

This site's research and writing leverages AI (Claude). By combining human judgment with AI research capabilities, we achieve broader and deeper observations.
