smello 0.1.1

Capture outgoing HTTP requests and inspect them in a local web dashboard

Smello

Capture outgoing HTTP requests from your Python code and browse them in a local web dashboard.

Like Mailpit, but for HTTP requests.

Setup

Install the client SDK and the server:

pip install smello smello-server

Start the server:

smello-server run

Add two lines to your code:

import smello
smello.init()

import requests
resp = requests.get("https://api.stripe.com/v1/charges")

# Browse captured requests at http://localhost:5110

Smello monkey-patches requests and httpx to capture all outgoing HTTP traffic. Browse results at http://localhost:5110.

What Smello Captures

• Method, URL, headers, and body
• Response status code, headers, and body
• Duration in milliseconds
• HTTP library used (requests or httpx)

Smello redacts sensitive headers (Authorization, X-Api-Key) by default.

Configuration

smello.init(
    server_url="http://localhost:5110",  # where to send captured data
    capture_hosts=["api.stripe.com"],    # only capture these hosts
    capture_all=True,                     # capture everything (default)
    ignore_hosts=["localhost"],          # skip these hosts
    redact_headers=["Authorization"],    # replace values with [REDACTED]
    enabled=True,                         # kill switch
)
