LuaSocket is a Lua extension library providing TCP and UDP transport support via C modules, plus Lua modules for common Internet protocols like SMTP, HTTP, and FTP. It also includes utility modules for MIME encoding, URL manipulation, and LTN12 filters, sinks, and sources.

Use cases

• make http requests from lua
• send email via smtp in lua
• upload and download files over ftp
• open tcp and udp sockets in lua
• encode and decode mime in lua
• parse and build urls in lua

When to choose

• you need low-level TCP/UDP networking in a Lua application
• you want simple HTTP, SMTP, or FTP client functionality in Lua
• you need a mature, MIT-licensed networking library compatible with Lua 5.1 through 5.4

When to avoid

• you need asynchronous or high-concurrency networking with an event loop
• you need modern TLS/HTTPS support out of the box
• you are not working in the Lua ecosystem
