The original
DNSChecker
A web tool that checks DNS propagation by querying public resolvers in many countries.
Replacements
Listings that take over the same core job as DNSChecker.
ViewDNS.info
A web collection of more than 20 DNS, IP and domain lookup tools, with a paid API.
ViewDNS.info offers more than 20 DNS, IP and WHOIS tools with historical data and a paid API, but no multi-country propagation view.
DNSsy
A free website that tests a domain's DNS health and offers live DNS, reverse, WHOIS and ping lookups.
DNSsy provides a DNS health report with recommendations and live cache-bypassing lookups, rather than showing propagation across resolvers worldwide.
intoDNS
A free web tool that checks a domain's DNS and mail server health and configuration.
intoDNS gives a single health report on DNS and mail servers with fix suggestions, but has no propagation view or monitoring.
MXToolbox
A web-based suite of DNS, MX, SPF, DMARC and blacklist lookups for diagnosing email delivery.
MXToolbox runs many DNS and email lookups, querying authoritative servers directly, with prompts for its paid service instead of global resolver comparisons.
Who.is
A web lookup for WHOIS, RDAP, DNS records, nameservers and IP ownership of any domain.
Who.is combines DNS record lookups with WHOIS, RDAP and IP ownership, plus optional paid monitoring for DNS changes, without a global propagation map.
whatsmydns.net
A free online tool that checks DNS propagation against nameservers in many countries.
whatsmydns.net also checks propagation across resolvers in many countries with an expected value field, but it does not describe automatic refresh or regex matching.
Globalping
A free service for running ping, traceroute, DNS, MTR and HTTP tests from probes worldwide.
Globalping runs DNS queries from volunteer probes worldwide through a web interface, CLI and API, and is open source, though it needs more setup than a propagation page.
Check-Host
Online tool that checks a host with ping, HTTP, TCP, UDP and DNS from servers worldwide.
Check-Host runs DNS checks from many worldwide locations alongside ping, HTTP, TCP and UDP tests, with an API, but the page carries hosting advertising.
Also worth comparing
These listings name DNSChecker as their own alternative, so the relationship runs both ways.
CAA Test
A web tool that checks the DNS CAA records published for a domain.
DNSChecker queries public resolvers in many countries for a wide range of record types, including DNSSEC records, but does not diagnose configuration errors.
Dig Web Interface
Online front end to dig for querying DNS records against public resolvers or chosen nameservers.
DNSChecker queries public resolvers in many countries at once with expected-value matching and auto-refresh, aimed at watching propagation rather than dig options.
Google Admin Toolbox Dig
Google's free web-based DNS lookup tool that queries a domain's records and shows the results.
DNSChecker queries public resolvers in many countries at once and can auto-refresh while a DNS change spreads, instead of showing one raw response from Google's side.
