One of Twitch's best features is its extensive API and integration system, allowing third party developers to work with the Twitch system to tweak things and provide a variety of handy improvements. The tools listed here are mainly of interest to broadcasters, but some may be of value to viewers too (especially moderators).
Also called "BTTV" or "Better Twitch.TV", this browser extension does a lot. It permits free-to-use emotes (which can even be used by non-affiliates), has various UI tweaks, an alternate emote picker, and more.
Download it from https://betterttv.com/ if you don't have it already!
NOTE: BTTV includes some paid features, including personal emotes. It can still be used to great effect for free.
Another browser extension, FFZ adds its own set of emotes, user interface improvements, and integrations.
Grab it from https://www.frankerfacez.com/.
NOTE: FFZ offers some benefits for donations but they are 100% optional.
Twitch Whispers can be a bit fiddly when you're in a full-screen game. They show up with a highlight saying who whispered you, but you can't read the actual message without clicking on it. Lisp Whispers will show you whispers as they arrive, and can be slid off onto a secondary monitor for easy access.
Access it at https://rosuav.github.io/LispWhispers/ and optionally open it in a popup window. It will need to be granted some permissions from Twitch.
Caught out by similar names and didn't notice that it was a new person in chat? The Greeting Mouse will highlight the first message from each person.
Chrome extension only at present (sorry, other browser users).
StreamLabs alerts are great, but the StreamLabs page itself tends to have a lot of notifications, and it constantly seems to be telling you about something. If that doesn't interest you, this extension will keep them out of your face. You can still click on the bell to see what's new, but it won't shake around with a red highlight any more.
At present, this also patches copy-to-clipboard on all Twitch pages, fixing a bug with emotes and newlines. Eventually this should be corrected upstream, and then this feature-ish will be removed.
Chrome extension only at present (sorry, other browser users).
Muting the video player can have unintended consequences, but you should retain full control of what you listen to. Chrome has some neat ways to mute and unmute tabs but the user interface is a little limited, and requires the mouse.
With this installed, you can:
- Press Ctrl-M to mute or unmute the current tab, independently of others
- Press Ctrl-U to unmute the current tab and protect it from Ctrl-Shift-5
- Press Ctrl-Shift-5 to immediately mute ALL tabs, even if focus isn't on Chrome at the time
- Press Ctrl-Shift-6 to unmute tabs muted with Ctrl-Shift-5 but no others
- Manage muting and unmuting via an external integration if desired.
Chrome extension to fix Chrome issues :)
