So, without further ado, here are top RTC.ON 2025 Must Read links!

FastRTC: The Real-Time Communication Library for Python

Hugging Face introduces FastRTC, a Python library designed to simplify the development of real-time audio and video applications. With features like automatic voice detection and built-in UI, FastRTC allows ML engineers to integrate WebRTC technology into their projects with minimum effort and knowledge requirements.

When you work at a software agency that builds its own products, at some point in time there must come a moment when someone asks: “What’s the most ridiculous thing we could build with the tech we develop?” For us, at Software Mansion, that question led us to creating Pufferfish, a game where players become fish, control their puffiness with lip movements, and battle in a real-time aquarium streamed to their phones.

It was a real tech demo designed to showcase our in-house tools: Fishjam, Smelter, and TypeGPU. Here’s how we turned faces into fish and made it technically impressive while doing so.

Out of the many impressive presentations at the conference, I chose a few that felt particularly meaningful to me because they closely matched my interests. I’d love to share more about them!

We hope you enjoy the RTC.ON newsletter as much as we do. It's great to see all of you joining us each month for a little multimedia walk through – thanks!
