There are paid options, like XSplit, but apps like Streamlabs and OBS offer a great free alternative. One thing to note is the need for a streaming application, where you set up your microphones, cameras and other elements. If live-streaming is a key part of your longer term aims then this could well be the platform for you.
Things like the ability to appoint moderators, reward ‘VIP’ subscribers with special perks, and receive instant financial tips from viewers. And it does it superbly, with a number of features designed specifically to help ‘Twitchers’ promote themselves in-broadcast. Where Facebook and YouTube benefit from being well known outside of live-streaming, Twitch benefits because live-streaming is all that it does. You’ll find people streaming almost anything within reason, from arts and crafts through to self-help lectures.
Although aimed predominantly at gamers, Twitch has carved itself a great niche as a place to build a community in many different areas.
