Which Programming Language is Used to Write Discord App?

Discord is a popular communication platform that has become an essential tool for gamers and non-gamers alike, and its popularity has grown exponentially since its launch in 2015. As Discord continues to evolve, many people are curious about the programming language used to create this powerful platform.

This article will discuss all the different programming languages used to build Discord’s application.

Programming Languages Used in Discord’s Application

This section will discuss different programming languages that are used to build the Discord application.


JavaScript programming language used in Discord’s application for developing the “Client side” of the application, which includes the user interface and the interaction with the user. JavaScript is highly flexible and scalable programming language, making it an ideal choice for Discord.


Rust is a coding language that is acclaimed for its rapid execution, robust memory management, and support for concurrent operations. Rust is used in Discord’s “Server-side application” to handle concurrency, performance, and security. In recent years, Rust has become increasingly popular among developers due to its suitability for constructing low-level software


Elixir is a functional programming language that is used in Discord’s “Server-side application” for building real-time features, such as notifications and chat rooms. 

React Native

React Native has gained popularity among developers for its cross-platform capabilities, enabling the sharing of code between the web and mobile versions of an application. Discord, for instance, has employed React Native in developing its mobile application. The framework’s ability to build cross-platform apps is a major factor behind its popularity.


TypeScript programming language is used to add static typing to JavaScript, making it more scalable and easier to maintain. Discord uses TypeScript for building its “Client-side application” to improve code quality, reduce errors, and enhance the overall development process.


Go, a programming language renowned for its speed and simplicity, is is utilized in Discord’s infrastructure to manage critical tasks such as service discovery, load balancing, and auto-scaling.


GraphQL is a powerful query language used for developing APIs, and it has been adopted by Discord for its API. By utilizing GraphQL, Discord benefits from efficient data retrieval and flexibility in data structures, making it an ideal choice for constructing complex and scalable APIs.


C++ is a low-level programming language that is used in Discord’s “Client application” for building performance-critical features. C++ is highly efficient and fast, making it an ideal choice for building high-performance software.


Discord’s application is built using various programming languages, each with its unique strengths and purposes. The client side of the application is primarily built using JavaScript, while the server side uses Rust and Elixir for performance and scalability. React Native is used for building a mobile application, TypeScript for improving code quality, and Go for handling the infrastructure. Additionally, GraphQL and C++ are used for building complex APIs and performance-critical features, respectively. The combination of these programming languages makes Discord’s application highly scalable, flexible, and efficient.
