Uninstall

Do the in-app step first

Dragging rexenv to the Bin does not uninstall it. rexenv installs privileged, system-level things that deleting the app cannot reach, and once the app is gone there is no button left to remove them.

What deleting the app would leave behind

• A root LaunchDaemon running the edge proxy on ports 80 and 443.
• /etc/resolver/* files for every dev TLD you used.
• Certificate authority trust in your login keychain.
• The always-on DNS agent.

None of those are harmful, but they are invisible, they survive reboots, and one of them keeps holding port 443.

Uninstall

1. In rexenv: Settings → Remove system changes.

   One admin prompt. It removes the edge daemon, the resolver files, the CA trust and the DNS agent.

2. Delete rexenv.app from Applications — or, if you installed with Homebrew:

   brew uninstall --cask rexenv
   brew untap rexenv/tap

3. Optionally, remove your data:

   rm -rf ~/Library/Application\ Support/dev.rexenv.rexenv/

Check that folder before deleting it

Your site files live there unless you moved the Sites folder or linked sites from elsewhere on disk. Look inside before you remove it — that directory also holds your databases and every downloaded component.

Linked sites are the exception in your favour: rexenv serves those folders in place and never copies or deletes them, so a linked project is untouched by any of this.

Keeping the data, removing the app

Doing step 1 and step 2 but not step 3 is a supported state. Reinstalling rexenv later picks the same directory back up with your sites and databases intact.
