Build scalable applications with 100x the performance of Scala’s Future

Use the full power of the Scala compiler to catch bugs at compile time

Easily build concurrent apps without deadlocks, race conditions, or complexity

Write sequential code that looks the same whether it’s asynchronous or synchronous

Build apps that never leak resources (including threads!), even when they fail

Inject test services into your app for fast, deterministic, and type-safe testing

Build apps that never lose errors, and which respond to failure locally and flexibly

Rapidly compose solutions to complex problems from simple building blocks
