facil.io – high performance web application C framework

facil.io is an evented network library. It provides high performance TCP/IP network services by using an evented design that was tested to provide an easy solution to the C10K problem.

facil.io includes a mini-framework for Web Applications, with a fast HTTP / WebSocket server, integrated Pub/Sub, optional Redis connectivity, easy JSON handling, Mustache template rendering and more nifty tidbits.

facil.io powers the HTTP/Websockets Ruby Iodine server and it can easily power your application as well.

This is free and open source software.

Key Features

  • Easy to code with and aims at minimizing the developer’s learning curve.
  • Supports both single-threaded and multi-threaded operation modes as well as a hybrid mode (multi-process with either a single-threaded or multi-threaded workers).
  • API is unified in style and the same types and API used for HTTP requests is used for JSON and Mustache rendering.
  • Source code library, making it easy to incorporate into any project. The API was designed for simplicity and extendability, which means writing new extensions and custom network protocols is easy.
  • Cross-platform support – runs under Linux, BSD, and macOS.
