Deterministic rule chain
HTTPeep runs traffic through a clear order: bypass, DNS, external proxy, rule match, request pipeline, origin, and response pipeline. Debugging decisions stay visible instead of being scattered across hidden panels.
mitmproxy is powerful and scriptable. HTTPeep keeps the proxy power but adds a desktop UI, centralized rules, zero-side-effect DNS Override, reusable URL templates, and API mocking that teams can share.

Why HTTPeep
HTTPeep focuses on repeatable debugging: clear rule execution, contained DNS changes, precise interception, HTTPS-ready mocks, reusable URL templates, and workflows that work in both GUI and CLI.
HTTPeep runs traffic through a clear order: bypass, DNS, external proxy, rule match, request pipeline, origin, and response pipeline. Debugging decisions stay visible instead of being scattered across hidden panels.
Switch API hosts to staging, VPN, LAN, or local services inside HTTPeep without touching system hosts files or leaking those changes to unrelated apps.
Mock API responses, map endpoints to local files, or route production domains to local services while keeping HTTPS interception active.
Pause matching requests or responses, edit headers and bodies, then continue, patch, or abort. It feels closer to source-code debugging than ad-hoc traffic editing.
Create rules for dynamic routes with variable templates instead of copying one-off URL patterns for every resource ID or environment.
The same proxy engine is available from the desktop app and httpeep-cli. MCP integration lets agents inspect sessions and manage rules through the same workflow.
mitmproxy is excellent when you want scriptable command-line control. HTTPeep targets teams that also need a fast desktop workflow for traffic tables, rule editing, DNS switching, and breakpoint review.
Python scripting is powerful, but not every debugging scenario should become code. HTTPeep rules make common matching, mock, DNS, proxy, and breakpoint flows easier to inspect and share.
URL variable templates make it practical to cover dynamic API routes without maintaining a long list of near-duplicate filters.
Use HTTPeep when your team needs clear rules, annotated hits, and GUI-driven HTTPS debugging.
