Capture traffic with the in-app browser

Use the in-app browser to browse web applications directly inside Postman. The in-app browser works like a standard web browser, enabling you to navigate to URLs, sign in to services, and interact with web applications without leaving Postman.

Inspecting network traffic can help you understand how an application communicates with APIs. Review page content, inspect network requests, open requests in Postman, and debug frontend behavior from a single interface. Agent Mode can automate browser workflows, generate tests, and create documentation from application behavior.

Inspect page content and network traffic

Inspect network traffic generated by web applications, review request details, and open requests directly in Postman for further exploration and testing. You can also use browser developer tools to inspect page behavior and troubleshoot issues.

Use Agent Mode with web applications

Agent Mode can interact with web applications in the in-app browser to help you explore APIs, generate tests and documentation, automate browser workflows, and debug application behavior.

For example, Agent Mode can navigate an application, complete user workflows, inspect the resulting API traffic, and generate Playwright tests based on its observations.
