ArcGIS Web AppBuilder

Description

The retirement of ArcGIS Web AppBuilder (developer edition, in ArcGIS Enterprise, and in ArcGIS Online) is driven by the retirement of the ArcGIS API 3.x for JavaScript. The developer edition of ArcGIS Web AppBuilder was retired in July 2024.

ArcGIS Web AppBuilder in ArcGIS Enterprise had its final release with ArcGIS Enterprise 11.5, released on May 22, 2025.

In ArcGIS Online, users will be unable to create new apps in ArcGIS Web AppBuilder by the Q1 2026 update but can still view and edit their existing apps until the Q4 2026 update. Existing apps will no longer be accessible in ArcGIS Online by the Q2 2027 update. At this point, ArcGIS Web AppBuilder will be retired in ArcGIS Online. ArcGIS Web AppBuilder will be supported by Esri until the Q2 2027 retirement date. Customers are encouraged to migrate from ArcGIS Web AppBuilder at their earliest convenience to ArcGIS Experience Builder, the recommended migration path. Apps created using Web AppBuilder must be reconfigured.

Recommendation

Deprecation does not impact Web AppBuilder availability, functionality, or Support (Product Lifecycle Support Phase). The Web AppBuilder retirement is expected to have a moderate impact on customers if they have rebuilt their apps using more modern technology such as ArcGIS Experience Builder.
