The Trello activity log is a built-in, chronological feed that records every significant action taken on a board, list, or card, from edits and moves to comments and member changes. It is automatically enabled on every Trello board and cannot be turned off, making it a simple but powerful tool for tracking project history, auditing changes, and keeping teams accountable.
What the Activity Log Tracks
Trello logs a wide range of actions, though the exact list depends on whether you are viewing the board-level log or the card-level log. In general, the log captures:
- Card creation, deletion, and archival
- List creation, renaming, and movement
- Card moves between lists or positions
- Label additions or removals
- Due date changes, including completion
- Checklist item additions and completions
- Member assignments and removals
- Comment additions, edits, and deletions
- Attachments added or removed
- Board invitations and permission changes
- Power-Up enablement or configuration
Each entry shows who performed the action, what they did, and when. The timestamp is relative (e.g., “2 hours ago”) but hovering over it reveals the exact date and time.
How to Access the Activity Log
There are two main ways to view the activity log, depending on the scope you need.
Board-level activity: Open your board, click the Show Menu button (the three dots or the “…” icon) in the top right, then select Activity. This displays a feed of all actions across the entire board, including list-level changes and card moves.
Card-level activity: Open any card and scroll down to the Activity section at the bottom. This shows only actions that occurred on that specific card, including comments, checklist updates, and due date changes. This is often more useful for reviewing a single task’s history.
You can also filter the board-level activity by clicking the Filter button within the Activity view, allowing you to see only certain action types (e.g., only comments or only member changes).
Why the Activity Log Matters
The activity log is more than just a record—it serves several practical purposes in daily project management:
- Accountability: Team members can see who did what and when, which reduces confusion and disputes.
- Audit trail: If a card is accidentally moved or deleted, the log shows exactly what happened and who did it, making recovery easier.
- Context: When you return to a board after a break, the log helps you quickly catch up on recent changes.
- Process improvement: Reviewing the log can reveal bottlenecks, such as cards moving back and forth between lists, indicating unclear workflows.
For example, if a card’s due date keeps getting pushed back, the log will show the history of those changes, helping you understand whether it’s a recurring issue or a one-off delay.
Activity Log vs. Card History
Many users confuse the board-level activity log with the card-level history. While they overlap, they are not identical. The board log includes list-level actions (like renaming a list) that don’t appear on any single card. Conversely, the card log includes comments, which are not shown in the board activity feed by default (though they can be filtered in).
If you need a complete record of everything that happened on a board, use the board-level Activity view. If you need to see the story of a single task, open the card and scroll to its Activity section. Both are equally accurate, but they serve different scopes.
Common Problems and Limitations
While the activity log is reliable, it has a few limitations users often encounter:
- No search within the log: The board-level activity feed does not have a text search box. You can filter by action type, but you cannot search for a specific keyword or member.
- Limited retention: Trello’s free plan keeps activity for a rolling period (roughly 30 days for board-level activity). Business and Enterprise plans retain it longer, but there is no unlimited history on free accounts.
- No export of the log alone: You cannot directly export the activity log as a CSV or PDF. However, you can use the Trello API (with some technical knowledge) to retrieve historical data.
- Clutter: On busy boards, the log can become noisy with minor actions like label changes, making it harder to spot significant events.
If you need a more robust audit trail, consider using a Power-Up like “Activity Log” or a third-party tool that syncs Trello data to a database.
Activity Log vs. Butler Automation
Butler is Trello’s built-in automation tool, and it interacts with the activity log in a specific way. When Butler performs an action (e.g., moving a card when a due date passes), that action is recorded in the activity log with a note that it was triggered by Butler. This is useful for distinguishing between human and automated changes.
However, Butler’s own rule history is separate. To see what rules are active and what they do, you go to the Butler section in the board menu, not the activity log. The activity log shows the results of Butler actions, not the rule configuration.
Frequently Asked Questions
Can I delete or edit entries in the activity log?
No. The activity log is immutable—you cannot delete or edit individual entries. This is by design to maintain an accurate audit trail. If you need to remove a comment, you can delete the comment itself, but the deletion action will still appear in the log.
Does the activity log show who viewed a board?
No. The activity log only records actions that change something (like moving a card or adding a comment). It does not track views or read-only access. If you need to know who has viewed a board, you would need a separate analytics tool or Power-Up.
Can I see the activity log for a specific member?
Yes, but only indirectly. On the board-level activity feed, you can filter by action type, but not by member. However, you can click on a member’s avatar in the board menu to see their cards, but not a consolidated log of their actions. For a per-member log, you would need to use the API or a third-party integration.
Does the activity log include changes made via the mobile app?
Yes. All actions performed on the Trello mobile app (iOS and Android) are recorded in the activity log just like actions on the web version. There is no distinction between platforms in the log.
How far back does the activity log go?
On the free plan, board-level activity is typically retained for about 30 days. On Business and Enterprise plans, retention is longer (often up to a year or more, depending on your plan). Card-level activity may be retained indefinitely, but this is not guaranteed. If you need long-term history, consider exporting your board data regularly via the “Print and Export” menu.
Activity Log Template
Below is a simple template you can use to manually track important activity if you need a record that goes beyond Trello’s built-in log or if you want to share a summary with stakeholders who don’t have board access.
| Date/Time | Member | Action | Card/List | Details |
|---|---|---|---|---|
| 2025-04-01 09:15 | Jane Doe | Moved card | Card: “Write report” | From “To Do” to “In Progress” |
| 2025-04-01 10:30 | John Smith | Added comment | Card: “Write report” | “I’ll have this done by noon.” |
| 2025-04-01 11:00 | Jane Doe | Changed due date | Card: “Write report” | From 2025-04-02 to 2025-04-01 |
Sample (fictional data). Copy the table and replace with your own entries.
To use this template, copy the table structure into a document or spreadsheet, then fill in each row as actions occur. This is particularly useful for external audits or for teams that need to keep a permanent record beyond Trello’s retention limits.
