5.4 Development Sites
The Websites area separates ordinary production sites from development sites: installs on local or staging hosts that you don't want counting against your license's activation limit. They appear on the Dev tab of the Websites page.
What counts as a development site
A site is treated as development when its host matches one of the platform's exempt patterns:
localhost*.local*.test*.dev*.ddev.site- and similar local / development host patterns
When a plugin on one of these hosts activates a license, Tangible Cloud records the site under Dev rather than Sites, and it is slot-exempt. It does not consume one of the grant's activation allowances. This lets you run a license across your local and staging environments without using up the slots you need for production sites.
The Dev tab
Open Websites and select the Dev tab. Each row shows the same columns as the main Sites list (domain, plugins, licenses, last-seen, and status), and the summary line reports how many development sites are detected.
