Tools I ship.

Small command-line tools for development, debugging, and security on macOS and Linux. All installable through a single Homebrew tap.

brew tap nickciolpan/tap

Projects.

Each is a single-purpose binary with no daemon and no telemetry. Source is on GitHub, formulae are in the tap.

dux

Rust macOS · Linux v0.1.0

Visual Docker debug helper. 105 curated docker commands with explainers, output-aware follow-ups (after docker ps, the next command's container arg is prefilled with parsed names), and two surfaces — terminal UI and browser UI — from one Rust binary.

brew install nickciolpan/tap/dux Site → github.com/nickciolpan/dux

cli-snitch

Go macOS v2.0.0

Terminal-based network connection monitor and firewall manager for macOS. Watches every outbound connection in real time, lets you allow/deny per process, persists rules, and ships a daemon mode for always-on protection.

brew install nickciolpan/tap/cli-snitch github.com/nickciolpan/snitcher

docker-scan-lite

macOS · Linux v1.1.0

Lightweight Docker image scanner for security analysis. Inspects images locally for known vulnerabilities and questionable configuration without the weight of full enterprise scanners.

brew install nickciolpan/tap/docker-scan-lite github.com/nickciolpan/docker-scan-lite

The tap.

All three projects live under one Homebrew tap. Tap once, install whichever you need.

1. Add the tap (one time)
brew tap nickciolpan/tap
2. Install any of the formulae
brew install nickciolpan/tap/dux
3. Update later
brew upgrade nickciolpan/tap/dux
