Trello Comment Scheduler

Built for a very specific annoyance. During my studies I often worked evenings and nights, and some clients did not appreciate getting Trello notifications at one in the morning. Keeping updates in a drafts file until a reasonable hour is not a system, it’s just something you forget to do.

Trello Comment Scheduler lets you write the update when you actually finish the work, and have it post when the client is awake.

You can schedule comments and card completion status changes, with quick options for 5 minutes, 15 minutes, an hour, today at 13:00, or tomorrow at 09:00 or 14:00. Anything scheduled shows up as an indicator in the card activity feed, and you can cancel it before it fires.

It’s a Chrome extension plus a Cloudflare Worker. The extension injects the scheduling controls into Trello’s card UI, and the Worker holds the queue and does the posting. The Worker is the part that matters, because a browser extension on its own can’t post a comment at 09:00 if your laptop is shut.
