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. Built by people who obsess over the details.
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 experimental Manifest V3 extensions for Firefox, Helium, and Chromium.
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. Settings and plugin history stay local. Some opt-in plugins contact external services.
Formula 1 level performance
Slick is heavily optimized to be fast and efficient so you can get what you need done faster. You are doing yourself a massive disservice if you are still using the stock Slack client.
