Listings that take over the same core job as Google Admin Toolbox Dig.
Dig Web Interface

Dig Web Interface can query several resolvers or authoritative servers at once, supports more dig options and gives shareable query URLs, with a plain interface aimed at dig users.
DNSChecker
A web tool that checks DNS propagation by querying public resolvers in many countries.
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.

whatsmydns.net checks record types such as MX, TXT and CAA against servers in many countries, and highlights mismatches against an expected value you enter.
DNSsy

DNSsy runs live lookups that bypass caches and adds a DNS health report with recommendations, though its toolset is smaller and the interface is dated.
ViewDNS.info
A web collection of more than 20 DNS, IP and domain lookup tools, with a paid API.
ViewDNS.info groups more than 20 DNS, IP and WHOIS tools with historical data, and offers a paid API, but some features need an account.

Who.is combines DNS record lookups with WHOIS, RDAP and IP ownership, and adds optional paid monitoring for DNS changes and certificate expiry.
MXToolbox

MXToolbox queries the authoritative server directly for MX lookups and adds SPF, DMARC and blacklist checks, with prompts for its paid service on the pages.
Also worth comparing
These listings name Google Admin Toolbox Dig as their own alternative, so the relationship runs both ways.
