Upgrade your CEP Extensions to the fast, modern UXP.
CEP (Common Extensibility Platform) has served us well, but UXP is the future. We help you migrate your CEP HTML/JS extensions to UXP, eliminating CEF overhead, dramatically improving performance, and securing your plugin's future in InDesign.
Experts in Adobe's extensibility transition.
Leave CEF overhead and ExtendScript behind. We build blazing-fast UXP plugins.
Goodbye ExtendScript
CEP relies on a messy bridge between modern JS and ancient ExtendScript. We rewrite your logic entirely in the unified, modern UXP DOM, eliminating evalScript bottlenecks.
Spectrum UI Upgrades
We migrate your legacy HTML/Bootstrap panels to Adobe's native Spectrum Web Components, ensuring your plugin looks like a seamless part of InDesign.
Network & File I/O Migration
UXP handles networking (fetch) and file systems differently than CEP's embedded Node.js. We expertly re-architect these critical data pathways for UXP compliance.
Cloud Integrations
Migrate DAM connectors and cloud asset panels from CEP's Node.js to UXP's native fetch API.
Data Merging
Port complex data-driven layout generators to run significantly faster on the UXP DOM.
Proofing Tools
Upgrade text-analysis and proofing extensions for better performance on large documents.
Custom Workflows
Convert internal agency CEP panels into lightning-fast UXP plugins for your design team.
Five stages, paired end-to-end.
Predictable delivery. No black-box sprints.
Analyze
We assess your CEP plugin, identifying Node.js dependencies and complex ExtendScript calls that need UXP equivalents.
Re-Architect
We design the new architecture, replacing the CEP/ExtendScript bridge with direct UXP DOM interactions.
Develop
We build the new UI in React with Spectrum components and rewrite the business logic in modern JavaScript.
Test
Comprehensive testing to ensure your new UXP plugin is faster, leaner, and functionally identical.
Launch
We package your new UXP plugin into a .ccx file and assist with Adobe Exchange distribution.
Six places it pays back in the first sprint.
