Sylviane Caffarel took her first steps into streaming in 2020. A multimedia student at the time, she saw it mainly as a way to practise her game development and content creation skills while meeting other enthusiasts. It quickly turned into something else: a real passion for streaming and the technology behind it. In 2025, she founded La_Syl Studio.

The studio now brings three trades together: building custom tools — stream widgets, sites wired into the Twitch, YouTube and Kick APIs, Streamer.bot actions — setting a channel up end to end, from hardware to software, and fixing things when they break at the worst possible moment. Sylviane still streams alongside all of it, and every tool is proven on her own channel before it is offered to anyone else: by a streamer, for streamers.
