What is Expirity?
Expirity is domain monitoring software that tracks expiry dates, SSL certificates, DNS records, and registrar changes across every domain you manage - so you find out about a problem from Expirity, not from a client, a downtime alert, or an expired-domain landing page.
If you’ve ever lost a domain to a missed renewal, had a certificate quietly expire on a production site, or found out a client’s nameservers changed weeks after the fact, Expirity exists to make sure that doesn’t happen again.
Who Expirity is for
Section titled “Who Expirity is for”Expirity is built for anyone responsible for domains that aren’t allowed to fail silently:
- Agencies and MSPs managing domains across many clients, who need organization and alerting that scales past a spreadsheet - see Agency Features.
- Developers and DevOps teams who want expiry, SSL, and DNS monitoring without building it themselves.
- Small businesses with a handful of domains who just want a single dashboard and a reliable email when something needs attention.
What Expirity monitors
Section titled “What Expirity monitors”| Monitor | What it catches |
|---|---|
| Domain expiry | Upcoming renewal deadlines, before they become a 404 page |
| SSL certificates | Expiring or invalid certificates, issuer changes |
| DNS records | Changes to A, AAAA, MX, TXT, NS, CAA, SPF, DMARC, and DNSSEC status |
| Registrar & nameservers | Unexpected registrar transfers or nameserver changes |

How it works
Section titled “How it works”- Connect with Google - no separate password to manage.
- Add your domains - manually, via CSV, or by importing directly from Namecheap, GoDaddy, or Route 53.
- Expirity checks continuously - daily on the free plan, near real-time on Pro and Agency.
- You get alerted before it matters - by email, and optionally Slack, Discord, or WhatsApp.
See the Quick Start guide to get your first domain monitored in under five minutes.
Plans built around how you actually use domains
Section titled “Plans built around how you actually use domains”Expirity’s plans aren’t just about how many domains you can add - Pro and Agency unlock near real-time checking, DNS change detection, and integrations, while Agency adds client folders, team roles, and per-client alert routing for anyone managing domains on behalf of others.
