Proxyman 6.3 adds HTTP/2 support, localhost traffic capture, XML prettify, and more

Proxyman 6.3 for Mac is now available, offering native tools to capture, decrypt, and mock HTTP and HTTPS requests and responses with extensive debugging features. This release brings experimental support for the HTTP/2 protocol, which improves performance and increases compatibility with modern web services using this new standard.

Building on its debugging capabilities, the update introduces automatic setup for capturing HTTP and HTTPS traffic from localhost when using Google Chrome and Firefox. Users can now capture traffic directly from addresses like localhost:3000 without modifying the hosts file, streamlining development workflows.

The response body viewer gains XML formatting with indentation and an expand or collapse gutter, allowing clearer inspection and navigation of large XML payloads. New command-line interface (CLI) commands and improved certificate validation expand workflow possibilities for developers.

In addition, this update introduces support for team subscription licenses and enhancements to the iOS simulator integration. Other changes include IPv4 address detection, updated toolbar icons for compatibility with macOS 26 Tahoe, and multiple bug fixes to further refine the application.
