Welcome to ZIO

ZIO is a zero-dependency Scala library for asynchronous and concurrent programming.

Powered by highly-scalable, non-blocking fibers that never waste or leak resources, ZIO lets you build scalable, resilient, and reactive applications that meet the needs of your business.

• High-performance. Build scalable applications with 100x the performance of Scala's Future.
• Type-safe. Use the full power of the Scala compiler to catch bugs at compile time.
• Concurrent. Easily build concurrent apps without deadlocks, race conditions, or complexity.
• Asynchronous. Write sequential code that looks the same whether it's asynchronous or synchronous.
• Resource-safe. Build apps that never leak resources (including threads!), even when they fail.
• Testable. Inject test services into your app for fast, deterministic, and type-safe testing.
• Resilient. Build apps that never lose errors, and which respond to failure locally and flexibly.
• Functional. Rapidly compose solutions to complex problems from simple building blocks.
