# parked_slots_full

HTTP 403 · Plan counts (SPEC §3.1, §3.2)

Every parked slot on your plan is in use. Delete a parked project, or upgrade for more. details lists your parked projects.

## Does retrying help?

Not until something else changes. The message says what: a plan, an add-on, a setting or a role. The same request then works.

## Already on the largest plan?

Studio is the largest plan. On Studio, use the message's other options, or email support@flatstack.dev and say what you need more of.

## The response

Every Flatstack error has this shape. `details`, when present, says more about this case.
