Web interface

The LangStream CLI provides a web interface that you can use to test your application. The web interface is available at http://localhost:8092/.

This interface displays:

• the application logs

• a chatbot-like interface to interact with the gateways

• a diagram of the application pipelines

• the JSON description of the application, both the logical and the physical description (execution plan)

The UI is started automatically when you run the application in docker mode (with langstream docker run...), but you can also start it manually using the langstream app ui command.

langstream apps ui application-id

With this command the CLI starts a local web service bound on local host and proxies the requests to the LangStream services - both the Control Plane and the API gateway.

The connection to the service is defined in the CLI configuration.
