notgate/Ironbullet ? reverse-engineered prompt

Build me a desktop app for automating HTTP workflows with a visual drag and drop pipeline editor.

I want to be able to chain together blocks for sending requests, parsing responses, transforming data, branching on conditions, looping, and basic browser automation. It should also support multi threaded jobs, proxy use, debug mode with step through execution, and a live viewer for requests and responses. Please include a clean desktop UI with a block palette, settings panel, and a way to run a single test input or a full list of inputs.

If it fits, add support for importing older config files, a plugin system for extra blocks, and export of a pipeline to code. Make it feel like a polished cross platform app, and look up current docs online if you need to.
