WireLens for Mac

The debugging proxy
that feels like a Mac app.

Capture every app on your Mac with one switch, decrypt the hosts you choose, and change any request with tools that live in their own window. Native, fast, and nothing leaves your Mac.

Capture

Everything on your Mac, and everything around it.

WireLens runs its proxy inside the app. There is no VPN to configure and no extension to approve in Privacy settings.

One switch for the whole Mac

Press ⌘R and every app that uses the system proxy flows through WireLens. The capture helper is approved once; stopping or quitting puts your settings back exactly as they were.

Know which app said what

Each flow is attributed to the process that opened the connection, and the sidebar groups everything by app and by domain, with live counts.

Beyond this Mac

Let phones, tablets, emulators and other Macs use your Mac as their proxy. WireLens serves them its certificate and asks before a new device can connect.

Tools

Seventeen tools. One window.

Tools opens beside your traffic with a searchable list, each tool with the same controls, the same pattern syntax and a tester that checks a rule before it goes live.

SSL ProxyingChoose which hosts get decrypted. Everything else is tunnelled untouched.
Capture Allow ListRecord matching hosts; the rest passes through without a row.
Block ListRefuse connections to matching hosts before they leave this Mac.

Windows

A window for every job.

The main window stays on your traffic. Everything else opens beside it, on the display you want, and every window has a shortcut.

Client Setup

Every runtime, captured.

Tools that ignore the system proxy get copy-paste setup with your real paths filled in, a shell that already has the variables set, and a one-line check that proves it worked. None of it ever turns certificate verification off.

The wirelens command

A live session in your terminal, plus commands to query, export, add rules and drive capture from scripts. Ships inside the app, always the same version.

An MCP server for your agent

Read-only by default, with rule and capture tools when you allow them. Secrets are redacted unless you ask, and your capture is never at risk.
