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.

0 inputs

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.
