Power-Ups turn Trello boards into living applications through additional features and integrations. You can add as many Power-Ups as you like on your boards regardless of your plan.
Go here to check out all our available Power-Ups.
Enabling a Power-Up
Enable Power-Ups by selecting “Power-Ups” from the board menu.
This will open the Power-Ups directory and you can enable a Power-Up by clicking on 'Enable' to activate the Power-Ups you would like to use. You can also list all Power-Ups currently enabled on the board by clicking on "Enabled" in the top left corner.
Disabling a Power-Up
To disable a Power-Up that is currently enabled, click the gear icon and then select "Disable".
The Trello App for Slack is enabled on a per-Workspace basis—for more information, read our article on the Trello App for Slack.
