Jira → Trello Duplicator

One-click duplicate the current Jira ticket into a Trello card — title, description, attachments, comments, status sync.

Stop copy-pasting Jira tickets into Trello. Open a ticket in Jira, click the extension, and a fully-formed Trello card appears on the right board — with the ticket's title, rich-text description, attachments (uploaded as real files, not dead links), comments, status, assignee, reporter and priority. Features • Per-project board mapping — route Jira project keys to specific Trello boards • Real attachment uploads — fetched from your authenticated Jira session • Status sync — moves or archives the card when the Jira status changes • Priority → colored label — auto-creates labels on the board if missing • Live Trello list picker with autosave • Smart re-link — detects when a linked Trello card was deleted and resets cleanly • Backup & restore — export/import all settings as JSON, with an optional separate toggle to include your Trello credentials • Dark mode, toast notifications, custom-domain support • Works on Jira Cloud (*.atlassian.net) and self-hosted Jira (opt-in) How it works 1. Add your Trello API key & token in Settings (guided links provided). 2. Map your Jira projects to Trello boards. 3. Open any Jira ticket, click the extension icon, hit "Create card". 4. Reopen the same ticket later to move/archive the card as the Jira status changes — or jump straight to the linked card with one click. Privacy Your data never leaves your browser except to call api.trello.com and your own Jira instance. No third-party servers, no analytics, no tracking. Settings exports never include your Trello credentials unless you explicitly tick the "Include credentials" checkbox.
