When the domain you want is already taken, Domain Watchdog tracks its history, warns you as it changes, and can try to register it as soon as it becomes available. Searching any domain returns its registrar, status, nameservers, and registration events from RDAP, the structured JSON successor to WHOIS. A timeline lays out the full lifecycle, from creation through renewals and transfers to final deletion, while deletion forecasting orders tracked domains by their expected drop window. Watchlists group domains with the events that matter, send alerts by email or as webhooks to Slack, Mattermost, or Discord, and publish an iCal feed plus RSS feeds for events and EPP status. Attach a connector for OVH, Gandi, Namecheap, AutoDNS, or Name.com, and an expired domain on the watchlist triggers an order attempt through that provider's API. The app also lists ICANN-accredited registrars and TLDs, and rate limiting with caching minimizes RDAP requests. Administrators can cap watchlists, domains per watchlist, and webhooks per watchlist, toggle public RDAP lookups, and add custom static content to the instance. Scripts can manage watchlists and connectors, search domains, and request user tokens through the documented REST API. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
