Plan limits
CardBoard is free to author, and paid to author at scale. The self-serve plans are Free, Pro, and Team. A negotiated Enterprise tier covers organizations that run multiple workspaces.
The monetization gate is capacity, plus one feature: tracker integrations (Azure DevOps, Jira, Linear, Shortcut, Trello) need a paid plan. MCP agents and guest collaboration are open on every plan, including Free. What you buy is board capacity, author seats, and tracker sync.
The two walls
Section titled “The two walls”| Free | Pro | Team | |
|---|---|---|---|
| Boards | 3 (can’t be deleted) | Unlimited | Unlimited |
| Author seats (members) | 1 | 1 | 3 included, +$15/mo per added author |
| Tracker sync (ADO, Jira, Linear, Shortcut, Trello) | No | Yes | Yes |
| Price | $0 | $10/mo | $45/mo for 3 authors |
Annual prices shown. Billed monthly: Pro $12/mo, Team $54/mo for 3 authors plus $18/mo per added author. Enterprise starts at $500/mo.
- Boards are the first wall. A free workspace gets three boards and can’t delete them, so once they fill up you move to Pro or Team for unlimited boards.
- Tracker sync needs a paid plan. Connecting Azure DevOps, Jira, Linear, Shortcut, or Trello starts on Pro. A workspace that downgrades to Free keeps its existing tracker connections syncing.
- A second author is the second wall. Free and Pro are single-member workspaces. Adding teammates who author requires Team, which adds seats.
What a seat is
Section titled “What a seat is”A seat is one member — an accountable, audit-attributable identity who can author: create boards, direct MCP agents acting in their name, and sync cards to your tracker.
Guests are free, forever. They view, comment, react, and edit non-tracker-linked cards, and they’re never a billing line item — you don’t pay for participation, only for the capacity to author. (Guests are blocked from governance and from attributable external writes: they can’t manage, delete, export, or edit tracker-linked cards.)
What’s the same on every plan
Section titled “What’s the same on every plan”- Unlimited cards per board
- MCP agents (REST API access additionally requires the workspace’s API flag)
- CSV import / export
- Unlimited free guests
The workspace audit log is on Team (90 days of history) and Enterprise (all of it). SAML SSO, retention policies, and legal hold are Enterprise.
Enterprise
Section titled “Enterprise”Enterprise is a negotiated, sales-led tier for organizations running multiple workspaces. Its defining capability is cross-workspace membership: a person can be a member of several workspaces (teams or projects) without paying a separate seat in each. Pricing is a negotiated combination of how many workspaces and how many people — not seats multiplied by workspace — so the same people can work across many teams at one cost. Enterprise also adds SAML SSO, the full audit history, and retention with legal hold.
