SlickKickass plugins
The most plugins of any Slack mod with more coming every week, and you can easily write your own in TypeScript.
The coolest Slack mod
Slick is everything you want in a client mod and nothing you don’t. It’s fast, open source, cross-platform, and fully customizable with plugins and themes.
Why Slick?
Cool Themes
Pick a built-in theme or write your own CSS in a Monaco editor, right inside Preferences.
Hassle free updates
Slick updates itself and Slack together. Updates are fast and seamless and always come with goodies.
Cross-platform
macOS, Windows, and Linux, plus an experimental Firefox extension for web. More platforms coming soon.
Open source
Licensed under the GPLv3. Read the code, contribute (if your epic), or fork it to your heart’s content.
Fully private
Slick collects nothing of its own and blocks Slack’s built-in telemetry. Your data is yours, not Slack’s or ours.
Oh goodie plugins!
