Run
npm install -g mtslack
in a terminal (or runsudo npx mtslack
if you don't want to install it globally) -
Run the command
sudo mtslack
(in Windows, you need to open the Terminal in Administrator Mode) -
You will be prompted with a menu with two options:
- Apply Theme
- Remove Theme
-
Select Apply Theme to apply the theme.
-
Open or Restart (with Cmd-Q) Slack

PROFIT!!!!!!!
The best way to revert to the default theme would be to use the backup copy you made and overwrite the patched Slack.app
There is also a Remove Theme
option in the menu but it is less robust.
mtslack
has an auto-update function. Whenever there is a new package available, a notification will appear on the bottom on your Slack Window prompting you to run the mtslack
command again to trigger the update. You will then need to run the command again to apply the updates.
Since version 2.0 you can also profit from a bunch of Slack Tweaks to make the application more enjoyable. You can find a button to open the Slack Tweaks on the channels sidebar.
This panel controls which tweak toggles are available. This doesn't actually toggle the tweaks themselves!.
Once you've enabled a tweak, a new toggle button will appear on the Channel Header. Pressing on these buttons will activate the tweak.
You can also activate the toggle using a shortcut.
These settings are saved in the application's Local Storage.
This button will toggle an overlay to display whenever settings are open.
This button will restore the old school presence icons in the sidebar
This button will dim absent people from the sidebar, making the present ones more prominent.
This button will loop over the available themes, allowing you to choose a theme in realtime.
Switch the fonts used in the app with the font you've defined in the Slack Tweak Settings.
Switch the monospace font size and family used in the app with the font you've defined in the Slack Tweak Settings.
Switch the current theme's accent color with the one of your choice. You can set the desired color in the Slack Tweak Settings.
Switch the current theme's links color with the one of your choice. You can set the desired color in the Slack Tweak Settings.
Please note that these tweaks rely on modifying the app realtime. There's a high chance further updates from Slack would break those tweaks. In this case please report to the repository, thanks!
This project consists in two parts:
- The CLI, used for applying the styles
- The Styles, written with Sass (Node-sass)
The cli is found in the lib
directory while the styles are found in the styles
directory.
Then run npm run styles
or npm run debugStyles
to compile the scss files in dist/slack.min.css
or dist/slack.css
Open Slack on the browser. It has the useful Developer Tools available to them so you can debug with ease.
To test your CSS, install a Stylish-like extension (https://chrome.google.com/webstore/detail/stylish-custom-themes-for/fjnbnpbmkenffdnngjfgmeleoegfcffe?hl=en) then create a new style for slack and paste the CSS inside and save.
You should already see all your styles applied. Please note that there are some differences between the web app and the native app.
- Run
npm run server
to run a local server - Run
watchStyles
orwatchScripts
to watch for changes in styles or code - Run
npm run local
to runapply
with the styles pointing to localhost - Run
npm run debug
IMPORTANT: Please make sure to have enabled "Disable cache when devtools is open" in Chrome Settings.
Also don't forget to re-apply the production styles before quitting :)
Instead of launching Slack normally, you'll need to enable developer mode to be able to inspect things.
