Curio is a coroutine-based concurrency library for Python using async/await, providing tasks, sockets, files, locks, queues, and structured concurrency with zero dependencies. The project was officially abandoned by its author in December 2025 after ten years, with no further maintenance expected.

Use cases

• write concurrent python programs with async await
• learn how async io works under the hood in python
• use structured concurrency in python
• build coroutine-based network servers with sockets
• study alternative to asyncio event loop design

When to choose

• you want a small, fast, zero-dependency async library for an existing codebase already using curio
• you are studying async programming concepts or David Beazley's educational talks
• you need structured concurrency primitives in a frozen, stable environment

When to avoid

• you are starting a new project - the library is abandoned with no future maintenance
• you need long-term support, security patches, or ecosystem compatibility
• you want broad third-party library support - asyncio is the standard
