Comparison Table Between Confluence Server & Cloud

Confluence Cloud has a more restrictive execution environment, limiting direct access to internal Confluence objects and Velocity context.

On the other hand, Confluence Data Center/Server allows greater flexibility, supporting a broader range of Velocity context variables and Confluence objects.

Feature	Confluence Data Center/Server	Confluence Cloud
Velocity context	Full support: `$generalUtil` & `$htmlUtil`by default	Limited support: `$body`, current `$page`, `$space`, and `$user`
Confluence objects	Supports `$config`, `$renderContext`, `$space`, `$content`, etc.	No access to internal Confluence objects
Apache Commons libraries	Not included by default, must be manually added	Includes `StringUtils`, `NumberUtils`, `CollectionUtils`, `SortTool`, `MathTool`, and `DateUtils`.
Macro execution flexibility	Can access additional Velocity context variables via system property, e.g., `CATALINA_OPTS="-Dmacro.required.velocity.context.keys=userAccessor,pageManager,action,request,response"`	Restricted execution environment, no access to system properties
Customization capability	High — allows deeper integration with Confluence internals	Limited — comes down to Confluence Cloud API capabilities
