PulseStack tracks each domain's registration expiry date and warns you before it lapses, so a missed renewal never quietly takes your website and email offline. We read the expiry straight from the domain's WHOIS and RDAP record.

Add a domain, tell us when to warn you, and let PulseStack watch the calendar so you do not have to.
Paste in any domain you own - .com, .co.uk, .io, .de, or almost any TLD. One domain uses one monitor, so you can watch a whole portfolio from a single account.
PulseStack looks up the registration record over RDAP, with WHOIS as a fallback, and pulls out the exact date your domain is due to expire. No registrar login required.
Choose how many days before expiry you want to hear about it. Add as many days-before thresholds as you like so the right people get a heads-up in good time.
As each threshold is reached, PulseStack fires an alert across your chosen channels. You renew with your registrar in plenty of time, and the site stays online.
Accurate expiry data, warnings on your own terms, and alerts that reach the right people.
PulseStack queries the domain's registration record and extracts the authoritative expiry date, so you are working from the same data the registry holds - not a guess or a diary note that someone forgot to update.
PulseStack watches from outside your registrar and tells you, in good time, when a domain is due to expire. It does not renew the domain for you and it does not touch your registrar account - you stay in full control of the renewal. That independence is the point: if a card on file expires or a renewal notice bounces, an outside watcher still catches it.
Domain expiry dates change slowly, so every plan keeps them under close watch. Your plan sets the shortest interval PulseStack uses across all your monitors, from five minutes on Free down to thirty seconds on Enterprise.
A clean run of checks, day after day, with a warning fired well before the expiry date arrives.
Domain expiry monitoring continuously tracks the registration expiration dates of your domain names using RDAP and WHOIS protocols. PulseStack™ queries authoritative registrar databases to determine exactly when each domain expires and sends progressive alerts as the deadline approaches. This prevents the catastrophic scenario where a domain lapses and becomes available for anyone to register.
Auto-renewal fails more often than people expect. The most common causes are expired payment cards on file, insufficient account balance, registrar account locked due to failed identity verification, DNS admin email bouncing so renewal notices never arrive, domains flagged for policy violations by the registrar, and registrar-specific issues like billing system outages. PulseStack acts as an independent safety net that monitors from outside your registrar, catching failures regardless of the cause.
Domain expiration follows a multi-stage process. First, the domain enters a grace period (typically 0 to 45 days depending on the registrar) where you can still renew at the normal price. Then it enters a redemption period (typically 30 days) where recovery costs hundreds of pounds. After that, the domain enters pending delete status for 5 days, then drops and becomes available for public registration. Domain squatters and competitors use automated tools to snap up valuable expired domains within milliseconds of them dropping.
PulseStack uses RDAP, the Registration Data Access Protocol, which is the modern successor to WHOIS. RDAP provides structured JSON responses from authoritative registrar databases, making the data more reliable and consistent than legacy WHOIS text parsing. Each check queries the RDAP server for the domain's registration events, extracts the expiration date, calculates days remaining, and compares against your configured alert thresholds.
WHOIS is the legacy protocol for querying domain registration data, returning unstructured text that varies between registrars. RDAP is the IETF-standard replacement that returns structured JSON with consistent field names across all registrars. RDAP also supports HTTPS, authentication, and internationalised domain names. ICANN has mandated RDAP support for all accredited registrars. PulseStack uses RDAP as the primary lookup method with WHOIS as a fallback for registries that have not yet fully migrated.
PulseStack sends progressive alerts at 90, 60, 30, 14, 7, and 1 day before expiry by default. The 90-day alert gives your accounts or procurement team time to process renewal through corporate approval workflows. The 30-day alert is your primary action trigger. The 7-day and 1-day alerts are urgent escalations. For critical business domains, we recommend configuring escalation policies so that late-stage alerts trigger phone calls and PagerDuty incidents rather than just email.
Yes. PulseStack monitors domains regardless of which registrar they are registered with. Whether your domains are spread across GoDaddy, Cloudflare, Namecheap, Google Domains, Amazon Route 53, or any ICANN-accredited registrar, PulseStack queries the authoritative RDAP servers for each TLD independently. You get a single unified dashboard showing expiry dates across your entire portfolio.
Yes. PulseStack tracks the nameservers associated with each domain and alerts you if they change unexpectedly. Unauthorised nameserver changes are a common indicator of domain hijacking, where an attacker gains control of your domain and redirects traffic to their servers. Detecting this within minutes rather than hours can mean the difference between a contained incident and a full-scale data breach.
Domain hijacking occurs when an unauthorised party gains control of your domain registration, typically through social engineering the registrar, exploiting a compromised registrar account, or intercepting renewal expiry. The attacker changes nameservers to redirect all traffic, including email, to servers they control. Continuous monitoring detects the early signs: unexpected WHOIS changes, nameserver modifications, or registrar transfer initiation. Immediate alerts give you time to contact your registrar and dispute the change before damage compounds.
Yes. PulseStack supports monitoring for all major TLDs including generic TLDs like .com, .org, .net, new gTLDs like .io, .app, .dev, and country-code TLDs like .co.uk, .de, .fr, .jp, and .au. RDAP coverage varies by registry, so some ccTLDs use WHOIS fallback. The expiry dates, registrar information, and nameserver data are normalised into a consistent format regardless of the underlying protocol used.
The free plan includes 50 monitors total, and each domain you track uses one monitor. Domain expiry checks run on a configurable interval, with the default being every 6 hours. This is sufficient because domain expiry dates change infrequently. Paid plans support higher monitor counts and faster check intervals for organisations managing large domain portfolios.
Yes. The domain expiry checker tool at the top of this page is completely free with no account required. Enter any domain to instantly see the registrar, registration date, expiry date, days remaining, nameservers, and domain status. For continuous monitoring with automated progressive alerts, sign up for a free account with 50 monitors included.
Domain expiry monitoring is part of PulseStack's complete infrastructure monitoring platform. A single domain can have multiple monitors covering different aspects: domain expiry for the registration, SSL monitoring for the certificate, HTTP monitoring for the website, DNS monitoring for record integrity, and port monitoring for service availability. All monitors share the same alert channels, incident management, status pages, and team collaboration features.
Add your domains, set your own warning windows, and let PulseStack sound the alarm long before anything lapses.
