WebRun charges for token usage, compute time, and proxy data transfer (when using WebRun-managed proxies).

​
What Tasks Cost

Real examples from production usage:
Task TypeTypical CostDuration
Simple search (Google, LinkedIn)$0.01~20s
Form filling (3-5 fields)$0.02~25s
Data extraction (10-20 items)$0.05~50s
Multi-step workflow (5+ tasks)$0.08~2min
Complex automation (10+ tasks)$0.30~5min
Actual costs vary based on page complexity and task specificity.

​
Compute

$0.02 per minute of active session time. Compute time runs from session creation until termination or inactivity timeout. Sessions can run indefinitely while active, but expire after 5 minutes of inactivity by default. WebRun provisions real desktop environments with dedicated resources for each session, ensuring consistent browser behavior across all tasks.

​
Proxy

Proxy ModeCost
WebRun-managed$4.00 per GB of data transfer
Custom (bring your own)No additional charge
WebRun-managed proxies route traffic through residential proxy pools with geographic targeting. Data transfer is measured across the entire session. Custom proxies incur no extra cost from WebRun — you pay your proxy provider directly. See the Proxies guide for configuration details.
Sessions remain billable until terminated. Set terminateOnCompletion: true on your final task or explicitly call terminate to avoid charges for the full timeout window.
