# Billing and limits

> Free-plan caps, Pro behavior, and history visibility.

Fortress has a Free plan and a paid Pro plan. Free is useful for trying the system with a small workspace; Pro removes the main operating caps.

## Free-plan caps

| Cap                      | Free limit | What counts                                                     |
| ------------------------ | ---------: | --------------------------------------------------------------- |
| Active orders            |          2 | Orders with `state = "active"`. Paused orders do not count.     |
| Active domains           |          2 | Domains with `state = "active"`. Archived domains do not count. |
| Concurrent agent actions |         25 | Open tasks assigned to an agent. Closed tasks do not count.     |

Open task statuses are `inbox`, `ready`, and `waiting`. Closed statuses are `done` and `dropped`.

## History visibility

Free workspaces see the most recent 30 days of primary workspace history.

This applies to:

* Orders
* Tasks/actions
* Projects
* Documents
* Notes
* Questions
* Search results
* MCP overview data

Paid workspaces see full history. Accounts in Stripe's `past_due` retry window keep Pro behavior while payment retries are active.

## Upgrade behavior

When a Free workspace crosses a cap, Fortress returns `CAP_EXCEEDED` and the web app opens the upgrade flow. Pro removes the Free caps and restores full history visibility.

## Downgrade behavior

Cap enforcement blocks new cap-increasing mutations. Completing, dropping, pausing, archiving, or unassigning work can reduce cap usage and should still be allowed.

<Tip>
  If you hit an order cap but do not need one of the routines right now, pause the order instead of
  deleting the instructions.
