WFN started as a hobby around 2010 and is an "extension" to the embedded Windows firewall, offering real time connections monitoring, connections map, bandwidth usage monitoring...
Its main feature being the Notifier alert itself, which tells you about outgoing connections attempts and allows you to allow or block them, either permanently or temporarily.
It has been made open source a few years ago.
Please read the documentation about the features and limitation of WFN.
Especially note that WFN is not a firewall itself!
All versions are available in the releases page.
Nightly
This version is automatically built on each PR merge, meaning that you'll get the most recent build. With the most recent features... and bugs 😁
2018.05 - v2.5 beta
Version 2.5 should be used (and should have been since its release, while a beta) as it fixes a lot of issues, has been modernized (both the code and the UI), is faster, more reliable... I'm keeping v2.0 in this list though as it was the mainly used version for years.
2018.03.03 - v2.0 beta 3
The latest release for version 2.0, kept here if you encounter issues with 2.5.
Keep in mind, beta versions are work in progress! Read the full description page before downloading!
WFN requires Windows 7 or later (with Microsoft .NET 4.5.2 or higher for version 2.0, version 2.5 comes as a standalone version which embeds the proper framework, i.e. .NET 6.0+).
Windows Server 2008 or later are not officially supported, but WFN should work fine on them.
**Screenshots are from v2.0 and are outdated. This page will be updated soon. **
