Toolkit
A fast, readable inspector for requests, responses, headers, and bodies — with image and JSON previews.
Answer specific requests locally. No code — perfect for edge cases and isolating from backends.
Capture a session, export to HAR, replay recorded responses as mocks.
Pause requests/responses to inspect or edit them on the fly.
Guided certificate install for iOS simulators, physical devices (QR), and Android.
Route your Mac's own traffic through the proxy with a single toggle.
Simulate latency, jitter, bandwidth limits, and packet loss to test the unhappy path.
A look inside
No account, no trial, no paywall. If it saves you time, a ⭐ on GitHub is the whole business model.
