A UNIVERSITY HOMEWORK ASSIGNMENT IN TURIN BECAME ONE OF THE BIGGEST NETWORK TOOLS ON GITHUB. His name is Giuliano Bellini. Computer engineering student at Polytechnic University of Turin. Course: System and Device Programming. The assignment: write a small program that logs network traffic to a file. Command line only. Submit it. Get a grade. Move on. Most students did that. Giuliano didn't. After he turned the project in, he kept working on it. Added a GUI. Added geo-location. Added a real-time chart. Added protocol detection. Added 24 language translations. Added webhook notifications. Added PCAP import that runs 2X faster than Wireshark. Three years later, GitHub picked it for their Accelerator Program and he started working on it full-time. He called it Sniffnet. Sniffer network. Today: → 33K GitHub stars → 1.2K forks → 2,771 commits → 64 contributors → 24 supported languages → 16 official releases → Sponsored by NLnet, ADS Fund, and IPinfo → Featured by Windows Central as a free GlassWire and Wireshark alternative His bio still says "pasta addicted, can't resist a good plate of spaghetti." His README still calls it "comfortably monitor your Internet traffic." The whole thing is written in Rust. 98.8% of the codebase. MIT and Apache-2.0 dual licensed. He refuses to add ads. He refuses to add telemetry. He refuses to lock anything behind a paid tier. A homework assignment from Italy is now used by network engineers in every country with internet. This is what coursework was supposed to lead to. Repo in the first comment.

终于找到一个能替代 Wireshark 的开源神器。 GitHub 3.7 万 Star 的 Sniffnet，把网络监控做成了普通人也能看懂的样子。 很多人打开 Wireshark 的第一反应都是： 看不懂，直接关闭。 而 Sniffnet 完全不同。 实时显示上传下载流量、连接主机、访问域名、IP 地理位置，甚至还能查看正在偷偷联网的软件。支持流量过滤、PCAP 导入导出、多网卡监控。 最关键的是界面非常舒服。 不用研究抓包规则，不用学习复杂命令，打开就能看到电脑到底在和谁通信。很多用户直接把它当成 GlassWire 的免费替代品。(Windows Central) Windows、macOS、Linux 全平台支持，Rust 编写，占用资源极低。(GitHub) 对于经常折腾代理、NAS、Docker、服务器的人来说，这绝对属于装机必备工具。 github.com/GyulyVGC/sniffnet

New domain name and official emails for Sniffnet 📨 Welcome “sniffnet[.]app”, which sounds less awkward than the old “[.]net” and is more fitting for a software project. We took the opportunity to also setup 3 official mailboxes for the project. sniffnet.app/news/new-domain…

¿Sabías que tu PC está enviando datos a servidores que NI SIQUIERA CONOCES… en este preciso momento? Sniffnet es la herramienta open-source que te muestra TODO tu tráfico de internet en tiempo real. Hecho en Rust ⚡ Cross-platform (Windows, Mac, Linux) REPOOO👇

sniffnet diye rust ile yazılmış bir araç var, internet trafiğini izlemek için. açıp ağ kartını seçiyorsun ve o an hangi cihaz nereye paket gönderiyor, hangi servisle konuşuyor, hangi ülkeye bağlanıyor hepsini görebiliyorsun. windows mac linux hepsinde çalışıyor, tek binary. hostların domain ve asn bilgisini çözüyor coğrafi konumu gösteriyorr. açık kaynak ve ücretsiz.

跨平台网络流量监控应用，让用户直观地查看和分析自己电脑的网络连接情况。 github.com/GyulyVGC/sniffnet Sniffnet 是一个用 Rust 写的开源桌面应用，用来监控网络流量。它基于 iced 做 GUI、pcap 做底层抓包，支持 Windows、macOS 和 Linux。 你可以选一个网络适配器开始抓包，设定过滤规则，实时看到流量统计图表、连接的地理位置、域名和 ASN 信息，还能识别 6000 多种上层服务协议。

Sniffnet 1.5 is finally out! 🎉 Discover which apps are using your network bandwidth, support custom IP blacklists, and more. sniffnet.net/news/v1.5/

Sniffnet just started being sponsored by @recallai 💖 They recently raised $38M and are now hiring in SF: go check them out if you want to build high-performance systems that process over 3TB/s of video at peak load! recall.ai/careers?ashby_jid=…

One of the most annoying programming challenges we’ve ever faced 🤦‍♂️ In today's blog post, we go through the details of supporting process identification. If implementing this feature seems like a no-brainer to you, well… read the post and be surprised. sniffnet.net/news/process-id…

JetBrains keeps supporting OSS projects that help developers learn, build, and grow. Recently, we supported @sniffnet and bottom, two tools that make developers’ lives easier 👉 jb.gg/rr_oss_25/2 We’re still looking for Rust projects to fund – which one should it be? Share in the comments 🗨️

Did you know that the source code behind Sniffnet is written using @rustrover by JetBrains? 🦀 Today we’re proud and excited to share that Sniffnet is included the latest blog post by @jetbrains itself, as part of the series “Open Source in Focus”. blog.jetbrains.com/blog/2025…

Sniffnet 1.4.2 is here 🥳️️️️ The most relevant additions are the ability to forward in-app notifications to a custom webhook URL, and the possibility to freeze packet captures. github.com/GyulyVGC/sniffnet…

A total of $13,247 donated! See the projects thriving thanks to your support: @sniffnet @revancedapp @grupoastian

Sniffnet version 1.4.1 is out 🎉 Enhanced filtering capabilities with support for BPF syntax, support for monitoring the 'any' interface on Linux, and extended configurations persistence are just some of the new features introduced with this release. github.com/GyulyVGC/sniffnet…

Sniffnet is 3 years old today 🥳 This is the perfect moment to glance back at the past year, and reflect on the importance of sustainability for a long-lived FOSS project. There is also a little spoiler in the blog post, so make sure to give it a read! sniffnet.net/news/third-anni…
