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.
Fiddler remains a known name in traffic debugging. HTTPeep gives modern teams a cleaner rule chain, zero-side-effect DNS Override, precise request interception, reusable templates, and one-time Pro pricing.

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.
HTTPeep emphasizes file-backed, reusable configuration rather than one-off session changes. A rule can document the match, action, DNS behavior, mock target, and breakpoint behavior in one place.
Instead of replacing every backend dependency, HTTPeep lets you keep real HTTPS traffic and mock only the endpoints or fields needed for the test.
When rules are named, saved, annotated, and template based, teams can reuse the same debug path instead of rediscovering a manual setup on every machine.
Download HTTPeep and keep traffic capture, DNS overrides, mocks, and breakpoints in one repeatable workflow.
