1. Install uv
2. Run $ uv install in project's root
3. set .env variables
4. uv run mitmproxy -s config.py -s flow_highlighter.py -s repeater.py -s nonoise.py -s sampler.py

Recommended Key Bindings:

$ cp .mitmproxy/keys.yaml ~/.mitmproxy

• Crtl + r to send flow to "Repeater"
• Shift + r/R to show the "Repeater"
• Shift + h/H to highlight a flow

Custom Commands:

• :nojs hide javascript flows
• :noimage hide image flows
• :nostyle hide style related flows
• :repeat send a copy of the current focused flow to repeater
• :repeater show repeater
• :highlight highlight current focused flow
• :freeze freeze a flow
• :freezer show freezed flows
• :rotate rotate upstream tor ip

Set scope on addon with @scope() decorator

@scope()
def request(flow: http.HTTPFlow):
    ...

Addons

• Flow Highlighter highlight the focused flow row
• Repeater like burpsuite repeater (mark flows as R and show/hide them)
• Sampler to extract json fields, query parameters, headers from request/response flows and save to a file for later fuzzing.
• No Noise to drop analytic and ad related request so they dont reach the upstream proxy (BurpSuite/Caido/Zap).
• Flow Freezer to capture and freeze a flow’s response to serve the frozen response for any future requests to the same url.
• Rotator to use tor as upstream and rotate its ip based on dynamic conditions (e.g., every 100 requests)
