What changes when you add an SFU (Mediasoup) in the middle of the pipeline?

I’m happy to share that Mafalda SFU has been recognised as “Best Scalable Real-Time Media Platform 2026” at the Spanish Business Awards organised by EU Business News.

You can find the official listing at https://www.eubusinessnews.com/winners/mafalda-sfu/, and the announcement published on the project website.

It’s always nice when a side project receives some external recognition, especially one that started mostly as an experiment.

At https://github.com/versatica/mediasoup/pull/777 (the lucky number :-D) I’ve published a PR that allows to create and use prebuild images of mediasoup, not needing to compile it at install on the target platform. This is done by compiling the Worker executables in advance for multiple platforms, and bundling them in the distributed package.

Although Mafalda SFU is mainly focused on vertical scaling of Mediasoup and the WebRTC stack, the main problem I’ve found companies are facing is about how to easily implement Medisoup horizontal scaling. I’ve been working on a solution for this problem for a while on, and since Mafalda is build on top of Mediasoup, it’s also needed to help it to provide transparent vertical and horizontal scaling, so let’s see how it works.

Mafalda SFU is a massively vertical and horizontal scalable SFU built on top of Mediasoup. This allow to have (theorically) unlimited sized WebRTC-based video room calls.
