# Limits

> Check your concurrency and team-member limits, and how many browser slots are in use.

Read your account's limits and current usage of them. Read-only.

<CodeGroup>
  ```python Python theme={null}
  from browser_use import BrowserUse

  client = BrowserUse()
  limits = client.project.limits()
  print(limits.concurrent_sessions.remaining, "browser slots free")
  ```

  ```bash curl theme={null}
  curl "https://api.browser-use.com/api/v1/project/limits" \
    -H "X-Browser-Use-API-Key: $BROWSER_USE_API_KEY"
  ```
</CodeGroup>

```json theme={null}
{
  "concurrentSessions": { "granted": 100, "active": 12, "remaining": 88 },
  "teamMembers": { "limit": 100 }
}
```

`concurrentSessions` counts every live browser (agent-driven or standalone). If `remaining` is 0, new runs queue or 429 until a browser frees up — [list idle browsers and stop them](/cloud/manage-browser) to free slots immediately.
