Uncurl.dev is a tool designed to convert curl commands into a user-friendly, shareable UI format. However, users have reported several limitations, including a narrow range of supported curl options, difficulty in input validation leading to frequent prompts for valid commands, and transparency concerns regarding how sensitive information is handled in the conversion process. Users have suggested improvements such as allowing better header modification, making the tool more client-side focused to enhance privacy, and enabling delete functionality for generated pages. There are also noted bugs and usability issues that could hinder user experience, as indicated by instances where common curl commands are not recognized by the platform.
