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.
Chrome DevTools is excellent for browser traffic. HTTPeep is a standalone proxy for browsers, mobile apps, desktop apps, CLI tools, and backend services, with rules that persist beyond a single tab.

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.
Chrome DevTools sees browser traffic. HTTPeep sees traffic from mobile apps, backend services, curl, SDKs, desktop apps, and devices that can point at a proxy.
When a mock, DNS override, or breakpoint is worth keeping, HTTPeep stores it as a reusable rule instead of leaving it as a temporary browser setup.
For non-browser clients, you need a real proxy with certificate management and MITM support. HTTPeep is built for that workflow.
Use HTTPeep when the request you need to debug does not come from a browser tab.
