libuv is a multi-platform C library focused on asynchronous I/O, providing an event loop backed by epoll, kqueue, and IOCP, plus async TCP/UDP sockets, DNS resolution, and file system operations. It was originally developed for Node.js and is also used by Luvit, Julia, and uvloop.

Use cases

• build an event loop for a cross-platform C application
• asynchronous TCP and UDP networking in C
• async file system operations with file change events
• embed an event loop in a language runtime like Node.js or Julia
• cross-platform async DNS resolution

When to choose

• you need a battle-tested, portable async I/O event loop in C
• you are building a runtime or server that needs epoll/kqueue/IOCP abstraction
• you want the actively maintained successor at libuv/libuv

When to avoid

• you want active development - this joyent mirror is abandoned; use libuv/libuv instead
• you need high-level async APIs in a managed language rather than a C library
• you need only simple blocking I/O without an event loop
