Briefly reviewed your product. Seems like OWASP ZAP is your competition: https://www.zaproxy.org/

It runs entirely in the browser so it uses the browser "native" frameworks.

Correct, ZAP is one of the main competitors, and the core functionality is the same. While there's a browser Head-up Display, the primary UI is still a Java desktop-based application.
