Where Twitch fits
Use it when watching or producing an ongoing live program rather than a finished clip.
Check before you choose
Review moderation and privacy settings before starting your own channel.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Regional rights and device support determine what a streaming service can provide. A personal media server is a different choice from a subscription catalog, and a free app does not mean every title is included.
