AI Summary

Mezz is a privacy tool that helps you understand what your own smart home devices are doing on the network. You set it up on an old computer with two network ports, and it creates a private wifi network where your IoT devices can connect. Everything the devices do—every website they contact, every service they call home to—gets logged in plain sight. It's designed for inspecting devices you own, not for impersonating other networks, and it includes clear warnings about using it responsibly.

How It Works

1
🤔 Curious about your smart home

You've heard stories about IoT devices sending data without you knowing, and you want to see exactly what your gadgets are really doing.

2
🖥️ Set up your inspection station

You take an old Linux computer with two network ports—one wifi adapter and one wired connection—and install Mezz on it.

3
📡 Create your private wifi network

Mezz transforms your computer into a dedicated wifi hotspot that your IoT devices can join, completely separate from your main home network.

4
📱 Connect your devices

You move your smart fridge, thermostat, or camera over to Mezz's network, just like joining any other wifi.

5
👀 Watch the traffic unfold

A live log shows every website and service your devices try to reach, with friendly names like 'kitchen-fridge.lan' instead of confusing numbers.

6
Want to dig deeper?
✅
Just watch the logs

DNS logging alone reveals where your devices connect without any extra setup.

🔓
Enable full inspection

Turn on traffic interception to see actual web request content, though apps with security certificates won't show in clear.

🎉 Know what your devices are doing

You can finally see exactly what your smart home gadgets are phoning home about—and decide if anything needs to change.

What is mezz?

Mezz is a self-contained wifi sandbox that turns a Linux machine with two network interfaces into a private, isolated network for your IoT devices. You get a dedicated wifi access point, DHCP/DNS services, NAT routing to your uplink, and a local domain so devices resolve as `kitchen-pi.lan`. Every DNS query gets logged, letting you see exactly where your smart fridge is phoning home. Built in Shell with Docker Compose, it ships three services by default and optionally adds mitmproxy for decrypting HTTP/HTTPS traffic. Everything runs in containers and reconfigures your host networking on startup.

Why is it gaining traction?

The DIY IoT inspection angle is the hook. Most people just let their smart devices blast traffic wherever without a second thought. Mezz gives you a zero-effort way to actually watch that conversation. Drop in a `.env`, run `docker compose up`, and suddenly you have full visibility. The optional mitmproxy profile is particularly clever -- flip a flag and you can intercept traffic from devices you want to dig into. It fills a specific niche between "I don't care what my devices do" and spinning up a full security research lab.

Who should use this?

Home automation enthusiasts paranoid about what their devices are doing. Security-minded developers who want to audit firmware before deploying. Anyone running self-hosted IoT setups who needs a quick way to isolate and inspect device traffic without impacting their main network. Not for beginners -- you need Linux networking knowledge and compatible hardware (wifi adapter with AP mode support).

Verdict

Mezz is a sharp idea with minimal traction (20 stars, 0.7% credibility score). The documentation is thorough and the Docker Compose approach is sound, but it's early-stage and the Shell implementation signals a hobby project rather than production tooling. If you have the hardware and want to see what your smart home is really up to, it's worth a weekend experiment. Just don't bet production workloads on it yet.
