Port Diagnostics & Conflict Resolution Tool for Windows

[alexnguyen03]

What feature or new tool do you think should be added to DevToys?

I would like to propose a new DevToys tool called “Port Diagnostics & Conflict Resolution Tool” designed to help Windows developers easily detect, analyze, and fix port conflicts — one of the most common productivity blockers in backend, web, microservices, Docker, and cloud development workflows

Why do you think this is needed?

Port-related issues occur extremely frequently on Windows (80–99% for active developers), yet current solutions require manual commands, external utilities, or deep OS knowledge. DevToys is the perfect place to streamline these tasks with a clean and safe UI

Solution/Idea

Provide an integrated Port Management tool inside DevToys that helps developers quickly diagnose and resolve port-related issues on Windows.
The feature should automatically detect conflicting processes, display detailed port usage information, and offer one-click actions such as terminating, releasing, or reassigning ports.
This aims to improve developer workflow by eliminating the need for external CLI tools or manual debugging.

The UI like this(AI generated from my idea):

Willingness to Contribute

I am willing to contribute this feature myself using DevToys.ExtensionKit, following the maintainers’ architectural guidance and feedback.

I will split contributions into several small PRs for easier review:

1. Core UI + port scanner
2. Conflict detector
3. Reserved ports viewer
4. NAT reset module
5. Firewall inspection
6. Docker port inspector
