# NebulaGraph tools overview

NebulaGraph provides the following command-line and data tools:

## Basic tools

- [ngql](https://dev-docs.nebula-graph.io/v5.3.2/utilities/ngql/): A command-line tool for interactively executing [GQL](https://dev-docs.nebula-graph.io/v5.3.2/database-gql-reference/overview/) queries. [Download standalone packages](https://dev-docs.nebula-graph.io/v5.3.2/utilities/ngql/#download).
- [ngctl](https://dev-docs.nebula-graph.io/v5.3.2/utilities/ngctl/): A command-line tool for managing the Meta service of NebulaGraph Database Developer Edition, such as logging in to and out of the Meta service and managing users. [Download standalone packages](https://dev-docs.nebula-graph.io/v5.3.2/utilities/ngctl/#download).

## Data import and export tools

[NebulaGraph Exchange](https://dev-docs.nebula-graph.io/v5.3.2/utilities/exchange/): An Apache Spark-based tool used to import data from multiple data sources into NebulaGraph Database Developer Edition and export data from NebulaGraph Database Developer Edition. [Download the package](https://dev-docs.nebula-graph.io/v5.3.2/utilities/exchange/deploy-exchange/#download).

## Visualization tools

- [NebulaGraph Studio](https://dev-docs.nebula-graph.io/v5.3.2/visualization/studio/): A browser-based tool for managing schemas, graph types, and graphs. Its built-in console can run GQL queries and return visualized results. Its integrated [graph exploration](https://dev-docs.nebula-graph.io/v5.3.2/visualization/studio/graph-exploration/) feature supports interactive exploration of data relationships.

## Verify a package

To check file integrity, download the SHA-256 checksum file next to the package link. The checksum file contains the package's SHA-256 checksum and filename.

Open a terminal in the download directory and replace `<package-name>` with the downloaded filename. Calculate the package's SHA-256 checksum with the command for your operating system:

LinuxmacOSWindows PowerShell

````
sha256sum "<package-name>"

````

````
shasum -a 256 "<package-name>"

````

````
Get-FileHash -Algorithm SHA256 -Path "<package-name>"

````

The calculated checksum must match the value in the checksum file; letter case does not matter. If the values differ, download the package again and repeat the check.
