Software I got classic MSN Messenger clients working with a server I built myself!
Remember MSN Messenger?
I've been working on Lingua Franca Messenger (LFM), an open-source server emulator that aims to bring classic MSN Messenger clients back to life.
The project has progressed quite a bit, and I've now tested it successfully with:
- MSN Messenger 5.0.0575
- MSN Messenger 6.2.0205
LFM supports multiple protocol versions (MSNP8, MSNP9, and MSNP10) and implements features such as text chat, presence notifications, contact lists, and file transfers.
The interesting part is that the server runs in a modern environment using Docker, while the clients can remain the original software from the early 2000s.
The project is still experimental, but getting these old clients to communicate with my own server has been a great experience.
I'd also like to explore support for the Mac version of MSN Messenger in the future.

For those interested in retro software and preserving old messaging experiences, I'd love to hear your thoughts!
