Create Faster, Lighter Experience Cloud Sites with Omnistudio Components and LWR
Summary
Lightning Web Runtime (LWR) offers a faster, lighter foundation for Experience Cloud sites using Salesforce Omnistudio components like Omniscripts and Flexcards. It improves load times by splitting the site into a static cached layer and a dynamic data-driven layer, enabling existing Aura-based flows to run without redesign. Teams can smoothly migrate to LWR by creating new sites with familiar tools and publishing updates to leverage CDN caching for better performance. This approach accelerates user experiences while retaining existing logic and workflows, making it easier to scale high-traffic Experience Cloud sites.
Takeaways
- LWR splits pages into cached static and dynamic data layers for faster load times.
- Omnistudio components run unchanged on LWR, letting teams migrate without rewrites.
- Publishing an LWR site updates the cached static layer in the CDN to refresh content.
- Experience Builder workflows stay consistent when adding Omnistudio components to LWR sites.
- Testing Aura and LWR sites side-by-side enables smooth transitions to improved performance.
A slow page can break your momentum — and your customer’s. When a form loads late or a step feels heavy, the journey loses its pace. Many teams built their first Experience Cloud sites with Aura, Salesforce’s legacy component-based framework used to create dynamic UIs. These Aura-based sites still support your flows and hold your work, but as your traffic grows, you may want something faster. That’s where Lightning Web Runtime (LWR) steps in. LWR supports both Omniscripts and Flexcards , enabling your key Salesforce Omnistudio components to work on a faster, lighter base. This support will be available in the Spring ’26 release and is already GA in preview sandboxes. With LWR, you keep the same logic, the same steps, and the same cards your teams depend on. Now, they run on a site built with a slim core where static content sits in a cached layer.
