-
mitmproxy
An interactive TLS-capable intercepting HTTP proxy for penetration testers and software developers.
> if the rendering engine and network fetching were easily separable - and you could insert your own steps into that pipeline, you could do all sorts of neat stuff.
Can’t that be done relatively easily with https://mitmproxy.org/?
