+
+**4 years ago** on this day, I made the very first commit to the Sniffnet GitHub repository and,
+as is tradition, today I'd like to celebrate the project's anniversary with a blog post.<br><br>
+Usually, the anniversary post is somewhat deep, reflective, and personal: over the past years I've talked about how being a maintainer changed my life,
+how important it is to balance Sniffnet development with a full-time job, and how sustainable open source is crucial to ensure a project's longevity.<br><br>
+I love discussing such topics because they pull the curtain back and show _the human that's behind the code_, but this year it'll be slightly different.<br>
+I think that delicate subjects must come out naturally without forcing them, so rather than repeating myself
+with another tear-jerking essay, or letting AI prose fake sentiments in my place,
+this time I'd like to take a more lighthearted route, sharing some fun facts and Sniffnet's visual evolution over the years.
+
+<hr>
+
+### <i>"The temptation to make a GUI is strong"</i>
+
+As many of you know, Sniffnet was <a href="{{ 'news/announcing-sniffnet' | relative_url }}">originally</a>
+a simple program that could only run from the command line to collect network traffic and print some rudimentary statistics.
+
+At the time I was a student, and I had just taken a Rust course.<br>
+I don't know why, it's probably that the Rust language hit me differently or that I was getting into the magic world of networking,
+but I felt like there was huge potential to make something way more complete and useful than a primitive terminal interface.
+
+The fact is that on the 20th of October 2022, I wrote this message to the friend I worked with on the first version of Sniffnet CLI:
+
+<div align="center">
+<img width="50%" alt="" src="{{ 'assets/img/post/fourth-anniversary/chat.jpeg' | relative_url }}">
+</div>
+
+Translated from Italian, the message just says: _"The temptation to make a GUI is strong"_.
+
+Attached to that message there was a short video showing a very early prototype of the graphical interface: a simple counter of the network packets being captured.<br>
+It was the first time I saw a window with Sniffnet's name on it, and I'm only sharing the video publicly today.
+
+<div align="center">
+    <video class="myShadow" controls muted preload="none" width="100%" height="auto"
+           poster="{{ 'assets/img/post/fourth-anniversary/gui_experiment_poster.jpg' | relative_url }}">
+        <source type="video/mp4" src="{{ 'assets/img/post/fourth-anniversary/gui_experiment.mp4' | relative_url }}">
+    </video>
+</div>
+
+I still remember the excitement I felt when I saw the window appear: in retrospect it was a small step, but at the time it felt like a huge leap.<br>
+In fact, initially I didn't even know if it was possible to make a graphical interface in Rust at all.
+
+After some research I found several frameworks that could help me with this, and ultimately I decided to go with <a target="_blank" rel="noopener" href="https://iced.rs">Iced</a>.<br>
+My first steps with Iced are still vivid, and I'd never have imagined that 4 years later Sniffnet would be prominently featured on their landing page as one of the most popular tools built with it.
+
+From there things moved quickly, and just a month later, on the 21st of November 2022, I released the first graphical interface as version 1.0.
+
+After all of this time, I was curious to look back at how the interface evolved, so I made a minimal widget that lets you travel through Sniffnet's main pages and releases.

+
+### The past 12 months
+
+Let's now shift to recent history.
+
+The past year saw the release of a <a href="{{ 'news/v1.5' | relative_url }}">new major version</a>, which finally brought the long-awaited process identification feature.<br>
+Implementing it was quite a <a href="{{ 'news/process-identification' | relative_url }}">challenge</a>, but I can say it was worth it: version 1.5.0 has
+been the most successful release of the project so far, with more than 100k downloads in the first two months after its launch.
+
+In addition to 1.5.0, three minor releases were published to introduce more features such as <a href="{{ 'news/remote-notifications' | relative_url }}">remote notifications</a>,
+BPF filtering, pausable packet captures, custom IP blacklist support, connection latency measurements,
+and signed installers for Windows (shoutout to <a target="_blank" rel="noopener" href="https://signpath.org">SignPath</a> for providing free code signing to Sniffnet).
+
+This year brought the total number of downloads to 530k, with a daily average of 657 downloads that is considerably higher than the previous year's 397 per day.
+
+<div align="center">
+<img alt="Downloads over the years" title="Downloads over the years" style="border-radius: 15px" src="{{ 'assets/img/post/fourth-anniversary/downloads.png' | relative_url }}" width="70%"/>
+</div>
+
+The GitHub repository has also gained 10k new stars, fewer than last year's 14k, but still a very good result considering that the project is more mature and has been around for a while.<br>
+This growth places Sniffnet in the top 0.0002% of all GitHub public repositories (678th<sup><a target="_blank" rel="noopener" title="Source: top1000repos.com" href="https://top1000repos.com/#GyulyVGC/sniffnet">[↗]</a></sup> out of 395 million<sup><a target="_blank" rel="noopener" title="Source: GitHub Octoverse 2025" href="https://github.blog/news-insights/octoverse/octoverse-a-new-developer-joins-github-every-second-as-ai-leads-typescript-to-1/">[↗]</a></sup>): something astonishing to even think about.
+
+<div align="center">
+<img alt="GitHub Stars over the years" title="GitHub Stars over the years" style="border-radius: 15px" src="{{ 'assets/img/post/fourth-anniversary/stars.png' | relative_url }}" width="70%"/>
+</div>
+
+Along the way I met new contributors who helped package Sniffnet as an AppImage, fixed various bugs, and added four new languages (bringing the total to 26 different translations by native speakers).
+
+Lately I've also had the pleasure of being contacted by <a target="_blank" rel="noopener" href="https://www.recall.ai/?ashby_jid=7b02811e-bc91-4ef2-925d-f56a5acac13b&utm_source=github&utm_medium=sponsorship&utm_campaign=sniffnet">recall.ai</a> and <a target="_blank" rel="noopener" href="https://www.coderabbit.ai">CodeRabbit</a>, two companies that started sponsoring Sniffnet with a recurring monthly donation.
+
+Last but not least, the project also has a new domain and custom email addresses, as <a href="{{ 'news/new-domain' | relative_url }}">announced</a> not long ago.
+
+<hr>
+
+### What's next
+
+If during the past couple of years I found the energy and motivation to keep working on Sniffnet until late at night,
+it was largely thanks to the substantial support I received from the European Commission's <a href="{{ 'news/ngi-program' | relative_url }}">Next Generation Internet</a> program.<br>
+Unfortunately, nothing lasts forever, and their funding is now coming to an end.
+
+I'll keep maintaining Sniffnet after the funding period, albeit probably not at the pace of the past months:
+in these cases _long-term consistency_ beats speed and intensity, keeps burnout at bay, and leaves room to enjoy life as much as development.
+
+The next major release will be version 1.6.0 and will finally make it possible to inspect network traffic from remote machines, firewalls, and routers.<br>
+You can already have a look at <a target="_blank" rel="noopener" href="https://github.com/GyulyVGC/sniffnet-agent"><code>sniffnet-agent</code></a>,
+a new companion program that will soon allow you to capture traffic from headless devices and send it to Sniffnet for inspection.
+

+</div>
+
+Other exciting features are already in the pipeline, so make sure to
+check the complete set of planned items in the usual <a target="_blank" rel="noopener" href="https://whimsical.com/Damodrdfx22V9jGnpHSCGo">Roadmap</a>.
+
+Until the next blog post, I wish Sniffnet a happy birthday!
