DOMAIN EXTENSION GUIDE

.stack Domain Names

Pre-launch

.stack is a proposed generic top-level domain associated with the idea of a stack: software layers, development environments, communities and organised systems. Publicly announced information identifies more than one organisation as claiming the string in the 2026 ICANN round, so it remains a contested proposed extension rather than a live namespace.
