Okio is a modern I/O library for Kotlin Multiplatform, Java, and Android that complements java.io and java.nio with ByteString, Buffer, Source, and Sink abstractions. It offers efficient, timeout-aware, copy-free byte handling and cross-platform filesystem access.

Use cases

• read and write files in Kotlin Multiplatform code
• efficiently buffer and move byte data between threads without copying
• encode and decode binary data as hex, base64, or UTF-8
• add timeouts to stream reads and writes
• access the filesystem uniformly across Android, JVM, Native, and WASI
• implement custom stream transformations like compression or encryption

When to choose

• you need a modern, multiplatform I/O layer beyond java.io/java.nio
• you are building on OkHttp or Android and want battle-tested byte handling
• you want ergonomic immutable byte strings and resizable buffers
• you need cross-platform filesystem APIs including Kotlin/Native and WASI

When to avoid

• you work outside the JVM/Kotlin ecosystem
• you only need simple one-off file reads already covered by your platform's standard library
• you need async non-blocking I/O rather than synchronous streams
