What are other options for streaming on Twitch besides OBS? Please provide a list with short summaries of the pros and cons of each option.
There are several options for streaming on Twitch besides OBS. Here are a couple of them:

1. Twitch Studio: Twitch Studio is a streaming app designed for new streamers that offers a guided setup process to help you get started with streaming on Twitch. It’s a great option if you’re new to streaming and want something that’s easy to use.

2. Restream Studio: Restream Studio is a browser-based live streaming software that allows you to go live on Twitch on desktop without using OBS.
