FlashScan Go
An optimised SNI bug host scanner written in Go — the fast, compiled take on the classic bugscanner approach.
What it is
FlashScan Go rewrites the bugscanner idea in Go for speed. It compiles to a single binary, scans fast and stays light on resources — no interpreter, no heavyweight dependencies.
Highlights
- Single compiled binary in Go
- Optimised, fast scanning
- Low resource usage
- Cross-platform builds
Why I built it
The Python bugscanners were slow on big lists. Go compiled that pain away — one binary, fast scans, minimal resources. It is my go-to when a large scan has to finish quickly.
