How to Customize SharePoint Communication Sites Beyond Default Web Parts
Question details
Site owners are looking for tools and methods to replace or extend the default widgets and web parts on SharePoint communication sites.

- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Redesigning or adding advanced functionality to SharePoint communication sites for specific internal or external audience needs.
- Observed behavior
- SharePoint Online lacks built-in features for extensive communication site redesigns, limiting users to standard configuration options and default web parts.
Before exploring custom development options, ensure you have Site Owner or Site Collection Administrator permissions and have thoroughly reviewed all out-of-the-box web parts to confirm they cannot meet your current requirements.
Utilize SharePoint Framework (SPFx) and Custom Apps
Since native redesign options are limited, leveraging the SharePoint Framework (SPFx), third-party apps, and developer community resources is the standard approach to extend functionality.
Modern SharePoint architecture does not support traditional customization methods like modifying master pages or injecting arbitrary code. Instead, Microsoft provides secure, scalable development models to add new capabilities.
Acknowledge that SharePoint Online restricts extensive user interface redesigns to maintain responsive design, accessibility, and platform stability across devices.
If you have access to development resources, use SPFx to build custom web parts, UI extensions, and field customizers that integrate seamlessly with the modern SharePoint experience.
Navigate to the Microsoft AppSource store to search for third-party SharePoint add-ins and ready-to-use widgets that provide the functionality missing from default web parts.
Visit the Microsoft Q&A Community website, navigate to the 'SharePoint Online' section, and post your specific requirements to get tailored recommendations from experienced SharePoint developers.
