Chrome Apps get one more reprieve

Chrome Apps have had a slow and careful deprecation, with the deadline pushed multiple times as Google attempts to smooth the transition for schools and developers alike. The current end of support schedule has Chrome Apps supported in kiosk mode through at least July 2026 with the long-term support channel receiving support until April 2027.

For schools, Chrome Apps are mission-critical, as most standardized testing providers still use Chrome Apps in kiosk mode. Eventually they will transition from Chrome Apps to Progressive Web Apps.

Schools should enable the KioskChromeAppsForceAllowed setting now in order to continue support through ChromeOS 150.
