Common uses

Variations / alternatives

There are multiple similarly named products (HTTP Debugger, IE HTTP Analyzer, HTTP Analyzer open-source projects). Some are Windows-specific (browser plugins/agents), others are cross-platform Java-based or commercial tools. Popular alternatives: Fiddler, Wireshark (packet-level), Charles Proxy, Burp Suite, browser DevTools.

Limitations / cautions

HTTPS decryption requires installing a local certificate — handle with care and remove when not needed.
GUI and workflows differ significantly between implementations; choose one matching your OS and browser.
Some variants are commercial; others are older/open-source and may be unmaintained.
