ProductGenerally available
Developer & ExtensibilityDeveloper & extensibility
Also known as App Builder, Adobe App Builder, Project Firefly
Adobe's framework for building custom cloud-native applications that extend CX Enterprise products and run on Adobe infrastructure. Apps are headless serverless actions on Adobe I/O Runtime, single-page apps served from a bundled CDN into the Experience Cloud shell, or UI extensions that plug into extension points in AEM, Commerce, Workfront and GenStudio. Storage, custom events, IMS authentication, a CLI, SDKs and CI/CD tooling are included. It is licensed in packs and was called Project Firefly until its rename in 2021.

Browser applications built on the JAMstack pattern: static front end on the App Builder CDN, back-end logic in Runtime web actions, and Adobe APIs called with the signed-in user's IMS token. They open inside experience.adobe.com next to Adobe's own applications and use the shell's client-side API (@adobe/exc-app) for the top bar, page and user information.
