Why Label Sync?

Sync Across Boards

Pick a source board, select your targets, and sync labels with one click. New labels appear everywhere they should.

Automatic Updates

Webhooks detect label changes instantly. Rename or recolor a label on your source board and all targets update automatically.

Preview Before You Sync

See exactly what will change before committing. No surprises — review creates and deletes before they happen.

Safe by Default

Additive-only sync means no labels are deleted unless you explicitly opt in. Your existing labels are always protected.

How it works

STEP01

Pick your source & targets

Open Label Sync from any Trello board — that becomes your source. Pick which other boards should mirror its labels, including ones in different workspaces.

STEP02

Preview every change

Before anything syncs, see exactly what will happen on every board — which labels will be created, their colors, and the total count. Audit-friendly by design: nothing touches your boards until you click Sync.

STEP03

Sync — labels everywhere, instantly

One click and every missing label appears on every target board — same names, same colors, ready to apply to cards. Enable auto-sync and any future change on the source propagates to all boards within seconds. No more drift.

FAQ

Head to the Trello Power-Up Marketplace and search for "Label Sync." Click "Add" to install it on your board. Once installed, open the Power-Up settings to authorize and start configuring your sync groups.

Yes! As long as you have access to the boards, Label Sync can sync labels across different Trello workspaces. Simply authorize with your Trello account, and all your accessible boards will appear in the configuration.

No. Label Sync is additive-only by default — it creates missing labels on target boards but never removes any. If you want to clean up orphaned labels, you can explicitly enable deletion in the settings, and you'll always see a preview of what would be removed before anything happens.

Trello webhooks fire whenever labels are created, updated, or deleted on your source board. Label Sync listens for these events and automatically propagates the changes to all target boards — no manual action required.

Each board you open the Power-Up on acts as a source for its own sync group. So you can set up multiple sync groups by configuring Label Sync on different source boards — each with its own set of target boards.
