Metronome is the XMPPd which runs on LW.Org IM and from recently also on Jappix's official service.
the software itself is a fork of Prosody IM, which I discovered in 2009 and got appealed by given it's rather low resource footprint, speed, modularity.. and is also the main reason I started learning Lua. While I'm (expecially with the 0.9 branch) still rather in "love" with Prosody itself, I slowly found myself at an impasse with how the project progressed and that I constantly needed to patch the code for it to meet my needs for LW.Org IM.
Perhaps when a rather large portion of the codebase diverged, and keeping backward compatibility to upstream became a problem I decided it was better to fork and keep a private control-versioned stub for LW.Org IM which I "codenamed" Metronome (While Prosody refers to the Metrics in Poetry, Metronomes are used to evaluate and keep Metrics in Music...).
Originally I didn't intend to release this at all, it was meant as I mentioned above to be a private fork which I would use for my needs, I didn't also want to drag the attention off the main project which is also what did hold me for all this time.
But it slowly became also evident how my views and the Prosody Team differ, and how often we're unable to communicate (to the point of almost, figurately, "getting at each other's throat"... more then once).
Also considering the recent interest to my little project (thanks also to Jappix and Valérian), and that I believe in free software, but differently to most of the OS Community... in which it's not the software itself which should be freely shared and remain free at all costs, but the inherent knowledge.
It's finally time to break the seals, and have people take their own conclusions.
Although this is not just "Prosody with a different name" as someone sarcastically told me today, it has different aims and different politics on how the codebase is mantained:
As you will be able to read from the README file or even the source code itself, differences span from everything above the inner stack (formally the stream parser, the stanza router, the server backend and util.stanza), mainly but not limited to:
Metronome currently is adopted as XMPP Server by the following sites / projects:
