## What it is
Simplewall is a lightweight, open-source Windows application for configuring network activity via the Windows Filtering Platform (WFP). It provides a simple interface for creating firewall rules, blocking telemetry, and monitoring dropped packets.

## Use cases
- block windows telemetry and spy traffic
- control which apps can access the network
- create custom firewall rules on windows
- log dropped packets
- replace windows firewall ui with a simpler tool

## When to choose
- you want a lightweight, portable firewall manager for windows
- you need to block windows spy/telemetry endpoints
- you want per-application network control without popups
- you need wsl or windows store app network filtering

## When to avoid
- you need a firewall for linux or macos
- you want a ui over the built-in windows firewall (simplewall uses WFP directly)
- you need enterprise centralized firewall management
- you are a beginner uncomfortable with advanced network rules
