WebAssembly Port Scanner

Written in Go with target WASM/WASI.<br>

Demo:

Watch the live demo on <a href="http://ports.sh/">ports.sh</a>

QuickStart

The WASM main function scans all the open ports in the specified range (see <code>main.go</code>), via 0.0.0.0 with no-cors fetch mode in Javascript level.<br>

• Discovers any TCP open port available on the visiting host.<br>
• One byte of response / filtered port is enough
• Scans TCP only (WASM has no UDP support yet)
• Uses golang 'http' API rather then 'net' API (better browser compatibility)

Setup

Please see <code>./build.sh</code>

Build and Run

Simply start an HTTP server locally, for example: <br><code>python3 -m http.server 5000</code><br>Or:<br><code>npm i -g serve && serve</code><br>
