The Data-Oriented Language for People Who Ship
Software from the Showcase and games shipping on Steam, all built with Odin.

Programming Done Right
Odin is a general-purpose programming language with distinct typing built for high performance, modern systems and data-oriented programming.
Odin is the C alternative for the Joy of Programming.

main :: proc() {
greetings := []string{"Hellope", "Bonjour", "こんにちは"}
for greeting, i in greetings {

b := [3]f32{4, 5, 6}
fmt.println(a * b) // [4, 10, 18] component-wise
fmt.println(a + b) // [5, 7, 9]
fmt.println(a.zyx) // [3, 2, 1] swizzle

}The Odin Principles
Simplicity
Odin has been designed for readability, scalability, and orthogonality of concepts. Simplicity is complicated to get right, clear is better than clever.
High Performance
Odin allows for the highest performance through low-level control over the memory layout, memory management and custom allocators and so much more.
For Modern Systems
Odin is designed from the bottom up for the modern computer, with built-in support for SOA data types, array programming, and other features.
Joy of Programming
We got into programming because we love to solve problems. Why shouldn't our tools bring us joy whilst doing it? Enjoy programming again, with Odin!
Batteries Included
Odin comes with high quality packages out of the box in its core library.
Odin provides official libraries for all major graphics APIs: OpenGL, Vulkan, Direct3D11, Direct3D12, Metal, wgpu, and WebGL 1 & 2.
Odin additionally brings you officially maintained bindings for popular libraries such as SDL2, GLFW, raylib, microui, miniaudio and much more, in its vendor library!
The Odin Community
Odin is Open Source
Odin is an open source programming language and contributions from the community are welcome! If you want to help out, check the issue tracker for open issues that may interest you. Those labelled help wanted are in particular need of community assistance right now.
