7) tcpdump
- Overview: tcpdump is a command-line packet capture tool for UNIX-like systems. It’s fast, scriptable, and useful for capturing traffic for later analysis (often used with Wireshark).
- Strengths:
- Extremely lightweight and powerful for filtering at capture time.
- Great for remote servers and low-footprint environments.
- Weaknesses:
- Not an HTTP-specific inspector; output is low-level unless analyzed with other tools.
- Requires familiarity with pcap filters and command-line usage.
- Best for: Server admins, ops, and situations where GUI tools aren’t available.
- Pricing: Free and open-source.
8) Postman (Proxy & Sniffer features)
- Overview: Known primarily as an API development and testing platform, Postman also includes proxy capture features and detailed request/response inspection, plus automated testing and monitoring.
- Strengths:
- Integrated API testing, documentation, and mocking with capture capabilities.
- Collections, tests, and CI-friendly features.
- Friendly UI for constructing and inspecting HTTP requests.
- Weaknesses:
- Capture/proxy features are less full-featured than dedicated proxies.

How to choose the right HTTP analyzer
- For low-level packet forensics: choose Wireshark or tcpdump.
- For developer-friendly request/response debugging and mobile testing: choose Charles, Fiddler, or HTTP Toolkit.
- For automated workflows and CI integration: choose mitmproxy or Postman.
- For security testing: choose Burp Suite.
- For production monitoring and observability: use cloud APMs and centralized proxies.
Practical tips
- Always install and trust proxy certificates only in controlled environments; never accept untrusted certificates on production devices.
- Use capture filters to reduce noise and storage use (e.g., capture only port ⁄443 or specific IP ranges).
- Combine tools: capture with tcpdump/Wireshark on servers, then analyze or replay with Postman, mitmproxy, or Burp for higher-level inspection.
- Consider compliance and privacy when capturing production traffic—mask or exclude sensitive fields.
Final thoughts
There’s no one-size-fits-all HTTP analyzer — choose the tool that matches your workflow: deep packet decoding (Wireshark), developer ergonomics (Fiddler/HTTP Toolkit/Charles), automation (mitmproxy), security testing (Burp), or production observability (APM/cloud proxies).
