Inko is a language for building concurrent software with confidence. Inko makes it easy to build concurrent software, without having to worry about unpredictable performance, unexpected runtime errors, race conditions, and type errors.
Inko features deterministic automatic memory management, move semantics, static typing, type-safe concurrency, efficient error handling, and more.
Inko supports 64-bits Linux, macOS and Windows, and installing Inko is quick and easy.

- Deterministic automatic memory management based on single ownership
- Easy concurrency through lightweight isolated processes
- Static typing
- Error handling done right
- An efficient, compact and portable bytecode interpreter
- Pattern matching
- Algebraic data types
Here's what "Hello, World!" looks like in Inko:
import std::stdio::STDOUT
class async Main {
fn async main {
STDOUT.new.print('Hello, World!')
}
}
And here's how you'd define a concurrent counter:
class async Counter {
let @value: Int
fn async mut increment {
@value += 1
}
fn async value -> Int {
@value.clone
}
}
class async Main {
fn async main {
let counter = Counter { @value = 0 }
# "Main" will wait for the results of these calls, without blocking any OS
# threads.
counter.increment
counter.increment
counter.value # => 2
}
}
Inko uses single ownership like Rust, but unlike Rust our implementation is easier and less frustrating to use. For example, defining self-referential data types such as doubly linked lists is trivial, and doesn't require unsafe code or raw pointers:
class Node[T] {
let @next: Option[Node[T]]
let @previous: Option[mut Node[T]]
let @value: T
}
class List[T] {
let @head: Option[Node[T]]
let @tail: Option[mut Node[T]]
}
