In this OBS tutorial, I’m showing you how to multi stream to Twitch, Kick, TikTok, and YouTube at the same time—without using Restream. The main thing you need is the Multiple RTMP Outputs plugin, and I walk you through installing it, then setting up each platform with the right server/RTMP URL and stream key so OBS can push to multiple destinations at once. If you’ve ever wanted to grow on more than one platform but didn’t want to run multiple PCs or juggle a bunch of apps, this is the cleanest beginner setup. After the multi stream plugin is running, I get into the stuff that makes multi streaming actually usable: combining your multi chat and alert feeds so you’re not missing messages from different platforms. I also show how I handle alerts with widgets so everything shows up in one place, and then we jump into vertical streaming for TikTok using Aitum’s Vertical plugin—because trying to force a vertical layout manually is a headache. I finish with stream info setup so your titles/categories aren’t a mess across platforms. No fluff—just the exact setup I’d use if I was starting from scratch in 2026.
