Domain Watcher

Domain Watcher keeps an eye on a watchlist of domains and alerts you the moment anything changes — expiry approaching, a drop coming, nameservers flipping to a parking service, or a wishlist name suddenly becoming available.

• Daily RDAP checks: status, expiry, nameservers, registrar
• Catches the signals that precede a drop, so you can backorder in time
• Works for your own domains too — never lose one to a lapsed renewal
• Self-hosted; alerts route through whatever you already use

Born from losing a domain I’d watched for years to a drop-catcher — by six days.
