A Mirror is counted whenever a card is duplicated to a board. So if one card is on two boards, that counts as one Mirror. If the same card is duplicated to an additional board (for a total of three boards) that counts as two Mirrors. If you get close to your plan limit, consider upgrading your plan or removing any Mirrors you are no longer using.
Mirror allows you to duplicate cards across multiple Trello boards. Syncs let you build workflows across multiple project management tools. You can sync a Trello board to a Jira project, a GitHub repository to an Asana project, and more!
Yes. We offer a 14-day trial so you can experiment with Mirror and see how it fits your workflow. After that, Mirror is a paid Power-Up.
