# Detach a hostname

`DELETE https://studio.grid82.app/v1/suites/{suiteId}/domains/{hostname}`

The hostname stops routing to this suite at once, for every app under it; people signed in there are signed out by the next request.

Records, users and members are untouched.

Requires the `schema:write` scope. Operation `domains.detach`. MCP tool `domains_detach`. CLI: `grid82 domains detach` (`npx grid82`).
