Domain Watch

Domain Watch tracks when your domains expire, so a lapsed renewal never catches you out. For each domain it shows days left, the expiry date and the registrar, sorted by urgency:

• Red — under two weeks, or expired
• Amber — inside your warning window
• Green — everything else

You get a one-time desktop notification the first time a domain drops under 14 days.

What you’ll need

• The domains you want to watch.

Add them one at a time in the widget’s ⚙ panel, as plain names — example.com, not https://example.com.

How the lookup works

Domain Watch does an RDAP registry lookup first (the modern, structured successor to WHOIS), falling back to plain WHOIS for TLDs that don’t publish RDAP yet.

No account or API key is involved: both are public registry queries.

Rate and caching

Lookups are cached for 12 hours per domain and run gently, one at a time. Registries rate-limit aggressively and a renewal date changes about once a year, so there’s nothing to gain from polling harder — and being a well-behaved client keeps the lookups working.

A domain whose TLD publishes neither RDAP nor a parseable WHOIS expiry will show as unknown rather than guessing. Some ccTLDs deliberately withhold expiry dates.
