Asana vs Trello
Comparison Summary
Asana scored 6.7 and Trello scored 6.0 on our project management tool test script.
Asana: Asana is the smoother tool to work in: pasting builds tasks, the CSV import understood all our columns and finished 200 rows in about 10 seconds, its AI was accurate, and the export keeps dependencies. But a new account runs on a 14-day trial, and much of what impressed us, from Gantt charts and rules to custom fields and the AI, is paid. The free plan is for two people and has list, board and calendar views.
Trello: Trello is still the quickest way to put a list of tasks on a board, and its free automation rules work well. But it is a Kanban tool first: on the free plan you get the board only, priorities have to be colour labels, there are no dependencies, no CSV import and no project-wide AI, and adding hundreds of cards is slow and capped at 100 at a time.
Editor's Verdict
Choose Asana if…
Best for: Teams ready to pay for Starter or Advanced who want a polished, fast-to-learn project tool with strong import and export.
- The CSV import recognised all seven of our columns with no manual mapping; 200 rows took about 10 seconds
- Pasting a multi-line list creates one task per line, and dates can be typed
- Rules can be built by describing them in a chat; ours fired within about 20 seconds
Choose Trello if…
Best for: Small teams and individuals who want a simple, visual Kanban board with a few automations.
- Pasting a multi-line list creates one card per line
- Free automation rules: ours moved a completed card within a second or two
- A recurring card rolls itself to next week when completed

Pros and cons
Asana
+ What works
- The CSV import recognised all seven of our columns with no manual mapping; 200 rows took about 10 seconds
- Pasting a multi-line list creates one task per line, and dates can be typed
- Rules can be built by describing them in a chat; ours fired within about 20 seconds
- Recurring tasks and rules did not get in each other's way
- Dash, the AI chat, got our project summary and the overdue question right
- The project CSV export includes subtasks and dependencies
- Removing a member took effect on their next page load and offers a handover of their tasks
- No admin rights, no startup entry and no services
− What falls short
- New accounts start a 14-day trial, so you see paid features first; there is no button to end it early
- The free plan is for 2 users, with list, board and calendar only; Gantt, Timeline, rules, custom fields and AI need Starter
- No priority field on the free plan: priorities are a custom field, which is a paid feature
- The import keeps “Done” as a label, does not mark those tasks complete and does not split “qa;legal” tags
- Heavy: about 14 seconds to a usable window and 1.4–1.8 GB of private memory, with a working set up to 3.2 GB
- Dash created subtasks without asking first, and an AI field suggestion kept coming back after we dismissed it
- Closing the window leaves Asana running; the uninstall leaves about 245 MB
- Marketing emails are pre-ticked at sign-up
Trello
+ What works
- Pasting a multi-line list creates one card per line
- Free automation rules: ours moved a completed card within a second or two
- A recurring card rolls itself to next week when completed
- The Store app installs in about a minute without admin rights and uninstalls without leaving anything behind
- Quick to learn, with a clean board
− What falls short
- Free plan: board view only; calendar, timeline and table are Premium
- No priority field (we used colour labels) and no task dependencies
- No CSV import: we could only paste titles, at most 100 cards at a time
- Bulk card creation is slow, and 13 of our 500 cards were lost when we reloaded before it finished
- No AI chat for summaries or overdue tasks; AI checklists are a paid feature
- A new account starts a 14-day Premium trial; free workspaces are capped at 10 boards
Privacy and security
What we saw on our own test PC. Each review also lists what the vendor states about data handling, training and certifications.
Asana
No startup entry
The installer added no startup entry, services, scheduled tasks or listening ports. The app does keep running after you close its window.
Marketing emails pre-ticked
Sign-up ticks “Get feature updates and tips via email” by default, and the industry question notes that Asana may contact you about its products.
Organization-wide by default
New projects are open to everyone in the organization as Editors until you make them private.
Left after uninstalling
A 236 MB profile folder with the signed-in session and a 10 MB updater.
Trello
Store app
Installed and removed through the Microsoft Store, with no startup entry, services or leftovers.
Silent card loss
Cards still being created when we reloaded the board were lost without a warning.
Deletion is two steps
A board must be closed before it can be permanently deleted, so closing alone keeps the data.
