Simple and Fast Multimedia Library (SFML) is a cross-platform software development library designed to provide a simple application programming interface (API) to various multimedia components in computers. It is written in C++ with bindings available for Ada, C, Crystal, D, Euphoria, Go, Java, Julia, .NET, Nim, OCaml, Python, Ruby, Rust, Node.js, Beef and Zuko.^[3] Experimental mobile ports were made available for Android and iOS with the release of SFML 2.2.^[4]

SFML handles creating and input to windows, and creating and managing OpenGL contexts. It also provides a graphics module for simple hardware acceleration of 2D computer graphics which includes text rendering using FreeType, an audio module that uses OpenAL, replaced by miniaudio as of v3.0.0,^[5] and a networking module for basic Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) communication.

SFML is free and open-source software provided under the terms of the zlib/png license. It is available on Linux, macOS, Windows and FreeBSD.^[6][7] The first version v1.0 was released on 9 August 2007, and the latest version, v3.0.0, was released on 21 December 2024.^[8]

SFML consists of various modules:

• System – vector and Unicode string classes, portable threading and timer facilities
• Window – window and input device management including support for joysticks, OpenGL context management
• Graphics – hardware acceleration of 2D graphics including sprites, polygons and text rendering
• Audio – hardware-accelerated spatialised audio playback and recording
• Network – TCP and UDP network sockets, data encapsulation facilities, HTTP and FTP classes

While the graphics module is one of the main features of SFML, developers who are interested in only creating an environment to program directly in OpenGL can do so by using the Window module on its own without the graphics module. Similarly, the other modules can also be used independently of each other, except for the System module which is used by all of the modules.

SFML is written in C++ and provides a C++ interface (it also provides a C interface through the official CSFML binding). Several language bindings exist that enable using SFML in other programming languages.^[3]

This table lists supported bindings for SFML as of 2024^[update].

¹ Official bindings

SFML provides the basic functions on which higher-level software can be built. Add-on libraries exist that provide added support for graphical user interfaces (GUIs),^[9][10] 2D lighting,^[11] particle systems and animation,^[12] video playback^[13] and tilemaps.^[14]

SFML is primarily used by hobbyist game developers, small independent video game developers, and startup companies consisting of several developers at most. Because SFML does not require writing large amounts of code, it has also been adopted by many Ludum Dare participants.^[15] Compared to older libraries such as Simple DirectMedia Layer (SDL) and Allegro, the SFML user base is relatively small but growing. As of 25 December 2024^[update], its GitHub software repository has been starred by over 10,000 users.^[16]

SFML has been used in teaching at universities and in scientific projects.^{[17][18][19][20][21][22]}
