A web client port-scanner written in GO, that supports the WASM/WASI interface for Browser WebAssembly runtime execution.
WebAssembly Port Scanner
Written in Go with target WASM/WASI.
The WASM main function scans all the open ports in the specified range (see main.go
), via 0.0.0.0 with no-cors fetch mode in Javascript level.
- Discovers any TCP open port available on the visiting host.
- 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)
