dstotijn/hetty ? reverse-engineered prompt

Build me an open source HTTP security testing tool that feels like a lighter, modern alternative to Burp Suite Pro.

I want a local app that runs an HTTP server with a MITM proxy, a web based admin interface, and a way to inspect, search, and organize captured traffic by project. It should let me intercept requests and responses, edit them, send them on, cancel them, and replay requests later. Please include scope controls so I can keep testing focused on the right targets, plus a built in HTTP client for manually crafting requests.

Make it easy to start from the command line, store data locally, and generate the root certificate and key if they do not already exist. If it makes sense, add a simple way to launch Chrome with the proxy already set up. Keep it clean, practical, and aimed at bug bounty and pentest workflows. If you need current implementation details, look up the docs online first.
