The mission of .SDK is to provide a namespace associated with the concept of sdk as a software development kit. The .SDK gTLD is intended to serve a broad range of registrants and users, including individuals, businesses, organizations, communities, projects, and other entities that identify with, relate to, or wish to be associated with the concept represented by the applied-for string.

When will .sdk be available?
ICANN has not set a date. The final list of applied-for strings comes on String Confirmation Day (November 17, 2026), community input and objections run until March 16, 2027, and ICANN processes applications after a prioritization draw in 2027. Registration opens only after ICANN delegates .sdk and its registry announces launch dates.
