simplehttp vs ZeroMQ: What are the differences?
Developers describe simplehttp as "A family of libraries and daemons built upon libevent that make high performance HTTP servers simple and straightforward to write". . On the other hand, ZeroMQ is detailed as "Fast, lightweight messaging library that allows you to design complex communication system without much effort". The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
simplehttp and ZeroMQ can be primarily classified as "Message Queue" tools.
simplehttp and ZeroMQ are both open source tools. It seems that ZeroMQ with 5.33K GitHub stars and 1.57K forks on GitHub has more adoption than simplehttp with 480 GitHub stars and 73 GitHub forks.
