# Owndle

> Owndle tracks every domain you own across every registrar — what you're overpaying on renewals, what your unused domains are worth, and which ones are drifting toward a missed-renewal cliff. Think "MoneySuperMarket for domains".

Owndle is agent-native. A founder can connect their AI agent — Claude Code, Cursor, Claude Desktop, or any MCP client — straight to their domain portfolio and ask it to audit costs, find renewal savings, value domains, or search for new names.

## Free tools (no account, no auth)

These are the fastest way to answer a question about a specific domain. All are public pages that work without signing in.

- Domain expiry checker — expiry date, days remaining, registrar, nameservers, DNSSEC. Read live from the registry over RDAP. https://owndle.com/tools/expiry-check
- Domain renewal price comparison — what every tracked registrar charges to renew a given TLD, cheapest first. https://owndle.com/tools/price-check
- Bulk WHOIS lookup — registrar, expiry and nameservers for up to 100 domains at once. https://owndle.com/tools/whois-bulk
- Domain search with social handle check — availability, alternatives ranked by TLD trust and brandability, matching social handles, and five-year cost of ownership. https://owndle.com/tools/domain-search
- Registrar lookup — which registrar a domain is actually registered with. https://owndle.com/tools/registrar-lookup
- Domain availability alert — which stage of the deletion lifecycle a taken domain is in, and whether it is likely to drop. https://owndle.com/tools/domain-alert

## Renewal price data

Renewal prices (not first-year promotional prices) across every registrar we track. Useful for answering "what does a .io cost per year" or "who is cheapest to renew a .com".

- All TLDs compared: https://owndle.com/prices
- One TLD, every registrar: https://owndle.com/prices/{tld} — e.g. /prices/com, /prices/io, /prices/ai
- One registrar, every TLD, versus the cheapest option: https://owndle.com/renewal-prices/{registrar} — e.g. /renewal-prices/godaddy
- Registrars ranked by average markup: https://owndle.com/registrars
- Head-to-head comparisons: https://owndle.com/compare
- How this data is sourced, how often it refreshes, and our rule that affiliate relationships never affect ranking order: https://owndle.com/methodology
