+# Accessory applications(Dashboard/Studio/Explorer)
+
+Nebula Graph Cloud integrates with Nebula Graph Studio, Nebula Dashboard, and Nebula Explorer.
+
+On the **Applications** page, ecosystem tools are different based on roles and privileges. The correspondence between different roles and privileges is as follows. The first column means the tools that the role can use, **Y** means the role has the corresponding privileges, and **N** means the role has no privileges.
+
+|Tools|OWNER|ROOT|USER|
+|:---|:---|:---|:---|
+|Dashboard|Y|Y|N|
+|Studio|N|Y|Y|
+|Explorer|N|Y|Y|
+
+## Dashboard
+
+Nebula Dashboard (Dashboard for short) is a visualization tool that monitors and manages the status of machines and services in Nebula Graph clusters. Currently Dashboard in Cloud only supports [Cluster monitoring](../../nebula-dashboard-ent/4.cluster-operator/2.monitor.md) page.
+
+## Studio
+
+Nebula Graph Studio (Studio in short) is a browser-based visualization tool to manage Nebula Graph. It provides you with a graphical user interface to manipulate graph schemas, import data, explore graph data, and run nGQL statements to retrieve data. With Studio, you can quickly become a graph exploration expert from scratch. For more information, see [What is Nebula Graph Studio](../../nebula-studio/about-studio/st-ug-what-is-graph-studio.md).
+
+## Explorer
+
+Nebula Explorer (Explorer in short) is a browser-based visualization tool. It is used with the Nebula Graph core to visualize interaction with graph data. Even without any experience in a graph database, you can quickly become a graph exploration expert. For more information, see [What is Nebula Explorer](../../nebula-explorer/about-explorer/ex-ug-what-is-explorer.md).
