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 before it lands. Native, fast, and everything stays on your machine.

macOS 14 Sonoma or later, Apple silicon · Free to use

Everything on your Mac, and everything around it.

One switch for the whole Mac

Press ⌘R and every app that honours the system proxy starts flowing through WireLens. Stop recording, or quit, and your network settings go back exactly as they were.

Know which app said what

Every request is labelled with the app that sent it, and the sidebar groups traffic by app and by domain, with live counts.

Beyond this Mac

Phones, tablets, emulators and other Macs can use this Mac as their proxy. WireLens hands them its certificate, and asks you before a new device is allowed in.

Every debugging tool. One window.

Tools opens beside your traffic. Every pane has the same controls and the same pattern syntax, plus a tester that tells you whether a rule will fire before you switch it on.

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.

Get any runtime through the proxy.

Node, Docker, Python and the rest ignore the system proxy. WireLens writes out the exact lines for each one, with your real certificate path already filled in, a shell that has the variables set, and a one-line check that it worked.

The wirelens command

A live session in your terminal, plus commands to query, export, add rules and drive capture from scripts.

An MCP server for your agent

Claude Code, Codex, Gemini CLI and Cursor. It only reads until you allow the rule and capture tools, and secrets stay redacted unless the agent asks for the raw value.

Start capturing on your Mac.

Capture and inspection stay free forever. Pro removes the limit on every tool.
