Authoritative RDAP lookups
Bulk Domain Expiry Checker
Normalize thousands of URLs, remove duplicates, and monitor reliable registry expiration data without fetching the submitted websites.
PSL parsing
UTC dates
Deduplicated
Add domains
Paste URLs or domains — one per line. Paths and subdomains are normalized automatically.
Accurate by design
Expiration comes from the registry RDAP event when available. Missing dates remain unknown; the tool never invents them.
Lifecycle aware
Redemption and pending-delete statuses override simple date math. Expired never automatically means available.
Safe input handling
URLs are parsed only. Submitted hosts are never fetched, and RDAP traffic is restricted to bootstrapped services.
