The SharePoint Add-in model is being fully retired for SharePoint Online.
While previously deprecated, existing Add-ins will stop working entirely for all tenants on April 2, 2026:
New SharePoint Online tenants created after November 1, 2024, will not support SharePoint Add-ins.
Acquiring Add-ins from the public marketplace already ceased on July 1, 2024.
For on-premises SharePoint, Add-ins deployed via an on-premises app catalog will continue to function, but store acquisition is also ceasing.
Start planning your migration away from SharePoint Add-ins immediately to avoid disruption.

*** OLD ***
Microsoft officially announced the deprecation of the SharePoint Add-in model for SharePoint Online in November 2023. While deprecated means no new investments, it was still supported for a period. However, it is being fully retired, and will stop working entirely for existing tenants on April 2, 2026. New tenants created after November 1, 2024, will not be able to use SharePoint Add-ins. Acquiring Add-ins from the public marketplace also ceased on July 1, 2024. For on-premises SharePoint, Add-ins will continue to work if deployed via an on-premises app catalog, but acquiring them from the store will also cease.
We strongly recommend migrating to modern development approaches such as the SharePoint Framework (SPFx).
