Описание тега appserver

Appserver .io is a next-generation PHP infrastructure consisting of a lightning fast webserver completely written in PHP including additional frequently needed services in one powerful bundle. You can use all of the services or only specifically selected services in your existing application with no additional tweaks. This is just what you need since we have eliminated the need for additional tools or additional services, appserver.io and PHP and you´re done!

http://appserver.io/ should not be confused with appserv which is an old, abandoned project that provided a LAMP stack for Windows.
