BrowserStack Local tunnel concurrency and session limits

BrowserStack Automate utilizes the Local binary to establish a secure tunnel for testing websites hosted on internal servers. While the browserstack.local capability enables this routing, the platform enforces limits on concurrent sessions based on the specific subscription tier.

There is uncertainty regarding how the platform handles session requests when the maximum concurrency limit is reached while a Local tunnel is active. Specifically, it is unclear if the system queues the requests or if the Local binary terminates the connection upon hitting the subscription ceiling.

• Does the platform queue incoming test requests when the concurrency limit is reached during a Local session?
• What is the expected behavior of the Local binary when the maximum number of parallel sessions is exceeded?
