A Comprehensive Guide to Adobe UXP: Why Now is the Time to Migrate from CEP

December 18, 2024

Custom Adobe Panel

The launch of UXP (Unified Extensibility Platform) marks a transformative shift in developing and deploying custom panels for Adobe software. For those using CEP (Common Extensibility Platform), UXP offers a leaner, faster, and more modern solution. Custom Adobe panels, also known as Adobe plugins, are integrated extensions within Adobe software. They are built to streamline repetitive tasks, integrate external tools, and enable tailored workflows for enhanced efficiency. 

As an expert in custom Adobe panel development, we guide you through the migration process, handle complex workflows, and deliver high-performance, UXP-compliant solutions tailored to your needs. 

Please contact us if you need help migrating or developing UXP's new custom panels for Adobe software. Let's explore Adobe UXP in depth.

What is UXP, and How Does It Differ from CEP?

Performance and architecture:

CEP relies on the Chromium Embedded Framework (CEF), which introduces high memory usage and performance bottlenecks.

UXP uses a lightweight runtime that is tightly integrated with Adobe apps, ensuring faster performance and lower resource consumption.

Simplified development:

CEP relies on HTML5 and Node.js, providing developers with familiar tools and libraries, but introduces potential challenges in managing compatibility and security..

UXP offers a modern, more secure development environment with streamlined APIs, reducing complexity and improving development efficiency.

Unified UI:

UXP supports Spectrum, Adobe’s unified design system. This allows custom panels to seamlessly match Creative Cloud apps' native look and feel.

Asynchronous Execution Without Freezing UI:

Improper handling of asynchronous operations in CEP can cause UI freezing, affecting user experience during long-running tasks.

UXP natively supports modern asynchronous patterns like async/await, ensuring smoother performance and preventing UI freezes.

Improved debugging:

UXP’s Developer Tool enables real-time debugging and quick previews, making the development process significantly more efficient.

Key Insights from Premiere Pro’s UXP Beta

Enhanced runtime: Faster loading, better stability, and reduced crashes in resource-heavy environments like video editing.

Backward compatibility: Many workflows can transition from CEP to UXP, though some advanced features may require adjustments.

Cross-app consistency: Extensions built on UXP function seamlessly across multiple Adobe apps with minimal code changes.

Common Questions About UXP vs. CEP

As experts in Adobe Panels development, we collected all common questions on the UXP, CEP, and migration process.

Can I migrate my CEP panels to UXP?

Some workflows may need adjustments to fit UXP’s updated API structure.

What happens to CEP extensions?

CEP extensions will still work, but Adobe prioritizes UXP for future updates and features.

What are UXP’s benefits for users?

Faster, more stable panels with easier installation and updates, improving overall user satisfaction.

Why Migrate to UXP Now?

  • Futureproof development: Adobe is entirely focused on UXP, making it essential to align with its roadmap.
  • Better user experience: UXP’s faster performance and Spectrum-based UI design create a smoother experience.
  • Avoid last-minute rush: Early migration avoids future bottlenecks and reduces technical debt.
  • Capitalize on updates: Adobe continuously improves UXP, adding new APIs and tools, with Premiere Pro already demonstrating its potential.

How to Start Migrating

  • Audit your extensions: Identify critical extensions and prioritize their migration.
  • Learn UXP: Use Adobe’s UXP documentation to understand its features and APIs.
  • Test in Beta: Experiment with Premiere Pro’s UXP beta to validate workflows.
  • Leverage Expert Help: Partner with First Line Outsourcing to streamline migration or develop new panels tailored to your needs.

UXP is not just an update—it’s the future of Adobe extensibility. Migrating now ensures your panels remain compatible, perform optimally, and align with Adobe’s vision.
