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.

Python

from browser_use import BrowserUse

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

curl "https://api.browser-use.com/api/v1/project/limits" \
  -H "X-Browser-Use-API-Key: $BROWSER_USE_API_KEY"

{
  "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 to free slots immediately.
