# Plans, simulation runs, and limits

Pricing and capacity follow the enforced Free, Solo, and Builder contracts.

## Use this when

Use this when choosing a plan or interpreting Usage.

## Before you start

A no-card 14-day Solo trial lands on permanent Free. Read [simulation run](/help/definitions.html#definition-simulation-run) and [simulation canvas](/help/definitions.html#definition-simulation-canvas) before comparing limits.

## Steps

| Plan | Price | Simulation runs / month | Canvas | Receipt availability | Active stores | Active workspaces |
| --- | --- | --- | --- | --- | --- | --- |
| Free | $0 | 10 | 14 world-days | 7 days | 1 | 1 |
| Solo | $60/month or $600/year | 30 | 30 world-days | 90 days | 1 | 1 |
| Builder | $199/month or $1,990/year | 100 included | 30-day runs can continue one aging store to 365 world-days | 365 days | 3 | 10 |

## Success looks like

Usage shows reserved, charged, released, remaining, and overage simulation runs under the current plan. Every tier receives the same receipt truth; plans change capacity, not evidence quality.

## If it fails

Free and Solo stop the exact over-limit action before work begins and name the limit; existing stores and evidence remain readable. Builder records usage beyond 100 included simulation runs, but automated overage invoicing is not enabled at launch. Archiving a store or workspace can release its active slot.
