What is Domainlert?
Domainlert is an Android domain management utility for website owners, developers, administrators, agencies and anyone who manages domains. It combines domain registration lookup, expiry tracking, DNS and TLS diagnostics, website health checks and portfolio organization in one app, making important domain information easier to review and monitor from a mobile device.
Check RDAP, DNS, DNSSEC and TLS
Use RDAP-first lookup to review registration status, registrar information, creation and expiration dates, nameservers, EPP lifecycle status, transfer lock and DNSSEC information. Domainlert can also inspect common DNS records, email-related DNS configuration and SSL/TLS certificates, helping you investigate both domain registration and technical readiness from one workflow.
Monitor and Organize Your Domain Portfolio
Add registered domains to your portfolio and organize them with Groups, Clients and Tags. Domainlert helps track expiry, website status, DNS and TLS changes, while monitoring alerts can highlight important updates such as registrar, nameserver, MX, DNSSEC, transfer-lock or certificate changes. Search, filters, reports, backups and portfolio summaries make larger domain collections easier to manage.
Domain Lookup & Health Tools
RDAP Domain Lookup
Check domains, subdomains or URLs and review registration status, registrar, important dates, nameservers, EPP status, transfer lock and other available RDAP information.
Domain Health Score
Review a 100-point Website & Email Readiness score based on expiry, transfer lock, DNS readiness, DNSSEC and TLS security with actionable issues.
DNS & DNSSEC Checker
Inspect common DNS records and review DNSSEC status and authoritative DNS responsiveness when investigating domain configuration.
Email Readiness Checks
Review supported MX, SPF and DMARC information to help identify common email-domain configuration issues.
SSL/TLS Certificate Checker
Inspect certificate trust, hostname matching, issuer, validity, expiry, wildcard handling, certificate chain status and SHA-256 fingerprint information.
Website Health Check
Check website availability using HTTPS-first connections, redirects, HTTP status, response latency and online or offline status.
Domain Discovery
Search selected TLDs for domain ideas, review progressive availability results and save potentially available domains to your Wishlist.
Domain Reports
Create supported text or PDF reports containing registration, expiry, health, DNSSEC, TLS, website status and optional domain-change information.
Portfolio Monitoring & Management

Review Changes and Reports

Domain Availability & Monitoring Note
A domain shown as Possibly Available should be verified with a domain registrar before registration because availability can change quickly and registry information may vary. DNS, website and TLS results can also change because of propagation, caching, network conditions or server configuration.
