Understanding RoboMongo (Robo 3T): A Comprehensive Guide

By: Published: February 9, 2022


Companies use Databases to store their business data and manage all their applications and websites. The number of servers increases as the business data grows and becomes cumbersome to manage when a Database Administrator or Developer pulls out a list of Databases.

MongoDB is a widely used NoSQL Database that supports the JSON data format and stores data in the document-oriented format. As companies use a data-driven approach and require data on a continuous basis. MongoDB stores business data with great flexibility. However, gradually it becomes unmanageable to operate huge volumes of data from the command-line tool. RoboMongo is a lightweight GUI tool that offers access to the MongoDB server with an interactive user interface.

RoboMongo allows users to easily view, access, edit MongoDB Databases from the graphical interface. It simplifies the workflow and saves time. In this article, you will learn about RoboMongo, its main features, and what are the technologies used in developing it. You will also go through the steps for the installation of RoboMongo and connecting to the host MongoDB server.

Introduction to RoboMongo (Robo 3T)

RoboMongo, now named Robo 3T, is a lightweight shell-centric cross-platform MongoDB management tool. It is a professional IDE, Client, and GUI (Graphic User Interface) for managing MongoDB Database by deeply integrating with the MongoDB shell. RoboMongo has been acquired by 3T Software Lab sand free-to-use software that any user can download and manage their MongoDB Database with ease. 

The 3T Software Labs also offers the paid version of this tool as Studio 3T, which is more advanced and embedded with more features. Unlike other MongoDB GUI admin tools, Robo 3T embeds the actual mongo shell in an additional tab along with the GUI so that users can also access the command-line tool. Robo 3T supports Windows, Mac, and Linux Operating Systems with easy installation.

With the help of Robo 3T, Users can interact with the data bricks using the visual indicators that save time than using a command-line shell. Robo 3T is supported by JSON and is highly specific to be used for MongoDB administrative tools to perform GUI-based tasks such as users can view, edit and delete documents. 

Robo 3T is a distributive native application that is fast and uses very little of the machine resources. Also, it’s an open-source project that offers innovative updates to the community. Robo 3T doesn’t emulate the mongo shell and embeds the same environment and engine.

Key Features of RoboMongo

Some of the main features of Robo 3T that makes it a are listed below:

1) Real Autocompletion

Apart from just analyzing the semantics of the code, RoboMongo also executes the code in the internal JavaScriot Virtual Machine that allows users to get runtime autocompletion and saves time.

2) Well Designed

RoboMongo is designed keeping in mind to ease the workflow and simplify the process of viewing, editing, updating the MongoDB Database. It comes with a user-friendly user interface and is a good start for beginners to learn about MongoDB shell.

3) Open-source

Robo 3T is a licensed open source project that makes it free to use for the public and has huge community support that adds many custom features.

4) Fully Asynchronous

RoboMongo is designed keeping in mind that all the operations performed on MongoDB are done asynchronously to deliver a non-blocking UI. This does not block the main application thread.

Installing RoboMongo on Windows

Now that you have understood about Robo 3T. In this section, you will go through the steps to the installation of Robo 3T on Windows and connect it to the MongoDB instance. You can connect your RoboMongo to an external server, VM, or a Scalegrid MongoDB instance. The following steps to install the RoboMongo on Windows are listed below:

Step 1: Installing the RoboMongo

  • Go to the Robo 3T official website here and download the RoboMongo software for Windows.
  • Here, click on the “Download Robo 3T” button, and it will ask to provide your contact details.
  • Then download the .exe or .zip file.
  • Once the download is complete, run the Robo 3T installer.
  • Click on the “Next” button to start the setup.
