mountebank - the first open source tool to provide multi-protocol over the wire test doubles.

There are some excellent HTTP/S stubbing libraries out there but no open source ones that let you also stub other protocols. mountebank was first built to support testing Java serialization over a mule-based TCP layer, supports HTTP/S, SMTP, and I'm working on first-class SOAP support. The only tools that provide this capability today are commercial (e.g. CA Lisa) and not nearly as friendly to CI/CD practices.

By the way, thanks for this thread. Independently of my own self-promotion, it's a great idea. Great open source developers are rarely good marketers, which means the best tools often rot in obscurity, and users of the tools rarely recognize that they can help by the simplest of actions. Find the ones you like on this page, star them, fork them, link to them. Help the open source community shine.
