Track every domain you own
before the renewal slips.
A free, browser-only portfolio manager for domain investors. Paste your list once — we look up each domain’s expiry, registrar, and nameservers from public RDAP data, then keep showing you what’s about to expire. No account, no upload, no monthly fee.

Catch expiries 30 / 7 / 0 days out
Color-coded buckets surface renewals you'd otherwise lose. Sort by expiry to plan a full month of renewals in one pass.
Bulk import in seconds
Paste 500 domains from a registrar export and the tool fans out parallel RDAP lookups. Done before your coffee cools.
Live data from the registry
RDAP is the modern replacement for WHOIS — pulled directly from each TLD's authoritative server. No 3rd-party scraper. Free.
One private session per visitor
Each browser session gets its own isolated portfolio. Refresh keeps your list. New tabs start fresh. Two people on the same computer never see each other's data.
CSV export anytime
One click to export the full portfolio as CSV. Re-import to a spreadsheet, share with a co-investor, or back up to your drive.
See nameserver drift
Spot when a domain accidentally goes back to a registrar's parking nameservers — a classic source of silent traffic loss.
How it works
Three steps, zero setup.
01
Paste your list
One domain per line, or paste a comma-separated list. The tool dedupes and ignores anything malformed.
02
We look up the registry
Each domain gets a real-time RDAP query (the modern WHOIS protocol). Expiry, registrar, nameservers all populated within seconds.
03
Sort by what's expiring
The KPI cards filter the table instantly. Click 'Expiring in 30 days' to see exactly what needs renewal action this month.

Domain Portfolio Manager
Track every domain you own across registrars. Catch renewals before they slip. Your portfolio is private to this browser session — refresh keeps it, new tabs start fresh, other people on this computer never see it.
Your portfolio is empty
Paste your domain list — one per line or comma-separated — and we’ll look up the expiry, registrar, and nameservers from public RDAP data.
Session-scoped storage: refresh keeps your portfolio, opening a new tab starts a fresh one. Export to CSV before closing the browser to keep your list across sessions.
One isolated portfolio per browser session.
Each session is keyed by a random ID stored in sessionStorage, so refreshes keep your list (without losing your work) while new tabs and other visitors on the same machine get their own private workspace. The server can’t read any of it.
For cross-session persistence, click Export CSV before closing the browser. Orphaned sessions older than 14 days are automatically wiped.
