Adobe's Common Extensibility Platform (CEP) resources: SDK, JavaScript libraries, documentation, and sample code for building HTML5/JavaScript extensions (panels) for Creative Cloud applications like Photoshop, Illustrator, and Premiere Pro. Includes the ZXP packaging/signing tool needed to distribute extensions.
Use cases
- build a custom panel for photoshop
- create an extension for premiere pro
- package a zxp file for adobe exchange
- communicate between a cep panel and the host app via csinterface
- learn how to develop creative cloud add-ons
- sign and package an adobe extension for distribution
When to choose
- you want to add custom UI panels to Adobe Creative Cloud apps using HTML/JavaScript
- you need official CEP libraries, cookbook docs, or sample extensions
- you plan to distribute extensions via Adobe Exchange or the Creative Cloud marketplace
When to avoid
- you want to build extensions for non-Adobe applications
- you need UXP-based modern extension development for newer Adobe apps
- you want a runtime-independent plugin system outside the Adobe ecosystem
