EnglishWhat is Network Watcher by Sebastián Λ?
Updated
Network Watcher is a multiplatform application listed on Sebastián Λ's personal site (argorar.github.io) that scans a local network to identify hosts and their open ports, and also verifies services such as HTTP, SMTP, and FTP. It was published on 2020-05-17 and is categorized under Software and Network. It is a practical fit if you want a quick, self-contained way to see which devices are reachable on your LAN and what they expose, rather than a full enterprise network-management suite.
What it does
Based on the site's description, the tool covers three layers of discovery:
- Host discovery — finds devices present on the local network.
- Port scanning — reports which ports are open on each identified host.
- Service verification — checks specific services, with HTTP, SMTP, and FTP named as examples.
The "multiplatform" label means it is intended to run across more than one operating system, though the listing does not specify which platforms or versions.
When it is useful
| Scenario | Why Network Watcher fits |
|---|---|
| Checking what is on your home or lab LAN | Combines host and port discovery in one pass |
| Confirming a service is actually reachable | Verifies HTTP, SMTP, and FTP directly |
| Working across different operating systems | Described as multiplatform |
| Needing a lightweight, single-purpose tool | Focused on scanning and service checks, not full monitoring |
What the listing does not tell you
The page entry is a short project description, so several details are simply not stated: the exact operating systems supported, the interface (CLI or GUI), installation method, license, and whether scanning is configurable (for example, custom port ranges or timeouts). If any of those matter for your decision, treat them as open questions to check in the project itself rather than assumptions.
How to evaluate it against alternatives
If your goal is a quick LAN inventory with service checks, Network Watcher is worth a look. If you need continuous monitoring, alerting, historical data, or deep protocol analysis, a dedicated network-monitoring platform will cover more ground. The deciding factors are usually: do you need one-off scans or ongoing monitoring, and do you need the three named service checks or broader protocol coverage.
Where to find it
Network Watcher is listed on Sebastián Λ's personal page at argorar.github.io under the Software and Network categories, alongside other projects such as WebM for Lazys, Northwind Crud, Dowi - Download Image, Cordic Graph, and Deep Dark. The listing links to a "Read More" page with the project's own details.
