Note

The project is in maintenance mode (only bugfixes and updates for new languages apis). Do not expect quick answers on github issues and/or pull requests (sorry for that) A big thanks to all of the users and contributors since 2009.

The uWSGI project

The uWSGI project aims at developing a full stack for building hosting services.

Application servers (for various programming languages and protocols), proxies, process managers and monitors are all implemented using a common api and a common configuration style.

Thanks to its pluggable architecture it can be extended to support more platforms and languages.

Currently, you can write plugins in C, C++ and Objective-C.

The "WSGI" part in the name is a tribute to the namesake Python standard, as it has been the first developed plugin for the project.

Versatility, performance, low-resource usage and reliability are the strengths of the project (and the only rules followed).

Included components (updated to latest stable release)

The Core (implements configuration, processes management, sockets creation, monitoring, logging, shared memory areas, ipc, cluster membership and the :doc:`SubscriptionServer`)

Request plugins (implement application server interfaces for various languages and platforms: WSGI, PSGI, Rack, Lua WSAPI, CGI, PHP, Go ...)

Gateways (implement load balancers, proxies and routers)

The :doc:`Emperor <Emperor>` (implements massive instances management and monitoring)

Loop engines (implement events and concurrency, components can be run in preforking, threaded, asynchronous/evented and green thread/coroutine modes. Various technologies are supported, including uGreen, Greenlet, Stackless, :doc:`Gevent <Gevent>`, Coro::AnyEvent, :doc:`Tornado <Tornado>`, Goroutines and Fibers)

Note

Contributors for documentation (in addition to code) are always welcome.
