MatrixNet
Little Snitch meets Wireshark — passive & open source
A passive macOS network monitor that unites two tools in one native app: per-app monitoring (which app connects where) + packet-level dissection (what's actually on the wire), with a correlation layer tying every captured packet back to its process. 100% passive — no NetworkExtension, no proxy, no HTTPS interception — so it runs alongside any VPN, proxy or filter without conflict. JA4 fingerprints, IPv4/IPv6 GeoIP map, threat flagging, and a desktop widget. Open source, Apache-2.0.
Hey Product Hunt 👋
I built MatrixNet because the two tools I always reached for never overlapped: Little Snitch tells you *which app* is connecting, and Wireshark shows you *what's on the wire* — but neither does both, and both sit inline.
MatrixNet does both in one native macOS app, and it's 100% passive: no NetworkExtension, no proxy, no HTTPS interception. It only reads kernel stats + a copy of each packet, so it runs happily alongside whatever VPN/proxy/filter you already use — zero conflict.
What's inside:
• Per-app connection monitoring + packet-level dissection, correlated so every packet maps back to its process
• JA4 TLS fingerprints, IPv4/IPv6 GeoIP world map, threat-list flagging
• Per-app history, a live menu-bar throughput readout, and a desktop widget
• Fully open source (Apache-2.0)
It's free and on GitHub. I'd love your feedback — especially on what you'd most want surfaced about your Mac's traffic. Happy to answer anything!
Curious how this handles HTTPS without actually intercepting anything - does the JA4 fingerprinting mean you're still doing some TLS handshake inspection, or is the packet-level view limited to just the metadata and headers?
finally something that shows the process and the raw packet on the same row, which is exactly what i wanted from little snitch without the nag popups. the passive approach actually working alongside my tunnel is a relief
