Trello Free: Unlimited Cards, Ten Boards

Trello free costs $0 and allows unlimited cards, unlimited Power-Ups, up to 10 boards per workspace, up to 10 collaborators, 250 workspace command runs a month and unlimited storage at 10MB per file. Standard at $5 a user monthly billed yearly adds unlimited boards, custom fields, advanced checklists and AI features.¹

Trello is the least restrictive free task board available, in the sense that the core object has never been limited. You can put as many cards as you want on a board.

The limits that do exist are on how many boards you can run and how many people can use them with you.

What the free plan actually includes

Unlimited Power-Ups on free is unusual and worth noting: the integrations bolt-ons are not gated, though some partner Power-Ups carry their own subscription.

Ten boards per workspace

A board is a project. Ten is enough for a personal setup and for a small team running a handful of concurrent workstreams.

It gets tight in organisations where every client, sprint and department wants its own board. The usual workaround is multiple workspaces, but each workspace has its own 10-collaborator cap, which fragments the team.

The alternative that people actually use is packing more onto fewer boards with more lists, which works until a board becomes unreadable.

Ten collaborators

This is the sharper limit. A collaborator is anyone who can edit a board, and free allows ten per workspace.

Reading is separate: boards can be made public for view-only access, which is how free users share progress with stakeholders without consuming seats.

Standard and above remove the collaborator cap while still charging per user, so cost scales with team size rather than the ceiling disappearing.

250 command runs

Butler automation is included on every tier. Free allows 250 workspace command runs a month, and a command run is one automated action.

A rule that moves a card when a checklist completes will consume one per trigger. At 250, that is roughly eight a day across the whole workspace.

Enough for a personal workflow, easily exhausted by a team. Standard raises it to 1,000.

What is missing that matters

Custom fields are paid only, which is a real limitation for anyone tracking structured data on cards. Priority dropdowns, effort estimates and dates beyond the due date all need them.

Advanced checklists with per-item assignees and due dates are also Standard. On free, a checklist is a plain list.

Views beyond the basic board are paid too: Calendar, Timeline, Table, Dashboard and Map all sit at Premium. Free gets the kanban board, the list, and the calendar in Planner view only.

For structured data on cards without paying, Airtable handles fields properly on its free tier, and ClickUp includes custom fields in a trial rather than blocking them.

When the free plan is enough

A personal kanban, a household project board, a small team of up to ten people running a handful of projects.

Anyone who only needs a visual task board and does not need to query or report on the data. Trello's strength is that a board is legible at a glance, and that costs nothing.

It is also the lowest-friction free tier in this series: no card, no expiry, and the core object unlimited. For one-to-one bookings rather than project boards, Calendly has a free tier with its own ceiling.

When it stops being enough

The eleventh collaborator, or the first time you need a custom field to sort by something that is not a label.

Standard at $5 a user monthly or $6 monthly is cheap per seat and removes the board, collaborator and automation caps in one step. Premium at $10 adds the reporting views, which is the tier for anyone who needs to see progress rather than move cards.

For a team that has outgrown boards entirely, Asana gives unlimited projects to two users and more structure per project.
