What it is

Naabu is a high-performance port scanner written in Go that performs fast SYN/CONNECT/UDP probes on single hosts or IP ranges to discover open ports. It combines raw socket scanning with service fingerprinting (powered by nmap-service-probes), DNS-based port discovery, and integration with the Shodan Internetdb API for passive reconnaissance, making it a lightweight alternative to traditional port scanners like Nmap for attack surface discovery in security testing workflows. The codebase is organized as a single Go module (github.com/projectdiscovery/naabu/v2) with functional packages: pkg/fingerprint/ handles service probing and nmap integration; pkg/routing/ manages platform-specific…

Start here

Read these in order:

  • pkg/protocol/protocol.go — Foundation: doesn't import anything internally and is imported by 22 other files. Read first to learn the vocabulary.
  • pkg/scan/arp.go — Foundation: imported by 17, no internal dependencies of its own.
  • pkg/port/port.go — Built on the foundation; imported by 26 downstream files.
  • pkg/runner/banners.go — Built on the foundation; imported by 3 downstream files.
  • pkg/result/results.go — Layer 2 — composes lower-level code into reusable abstractions (imported 15×).

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository with git clone https://github.com/projectdiscovery/naabu.git && cd naabu. Install dependencies using go mod download (inferred from the go.mod manifest). Build the binary with `go build -o naabu…

Daily commands:

…shortened for this brief.

Key cautions & unknowns

  • Concentrated ownership — top contributor handles 51% of recent commits
  • Raw socket scanning requires root/admin privileges on all platforms; the code checks this via pkg/privileges but gracefully degrades to TCP connect probes. Platform-specific routing logic (pkg/routing/router_*.go)…
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
