2026-06-26
TEST TOOL
• New Test tool that supports scripting, assertions and variable extraction.
• Supports all testing payloads and options you're already familiar with.
• The scope of functionality built into this tool is truly something that has never been done before in an iOS app. It took years of work to get to this point. I hope you like it as much as we do.
TRANSFORM TOOL
• Convert text or binary input data using transform recipes of multiple operations.
• Auto decoder that automatically finds a chain of operations that decodes given data.
• Lets you save current transform recipe as a favorite to use as part of testing.
• New Xcode color theme.
• Allows using {{variable}} syntax in input fields of Authentication and Rewrite rules.
• Adds new transform operations for data decoding, string escaping and converting charset.
• Improvements to navigation in all tools.
• Visual fixes and other improvements.
Changes in this version:
• Fixes to Zstandard decompression.
• Fixes to decoding of binary formats.
Notice how we bring new features and major improvements in every app update? If you like Proxygen app and it helps you debug network traffic then please tell your friends and colleagues about it. That would help a lot!
