I am a Burp guy, but lately Caido[1] has been trending, pretty lightweight and can be ran in headless mode. It's still very security-oriented (as Burp Suite is), but might be worth your time, notably as you can run it on a VPS/container to proxy all your traffic through it (which is by-design, contrary to my beloved burp/zap)
