The original title is "Nexus Engine: A cross-platform dev environment provisioning tool in Go"

Short summary

A 14-year-old developer built Nexus, a cross-platform environment provisioning engine written in Go that turns a fresh OS into a fully configured dev machine with one command. It supports multiple Linux package managers (apt, pacman, dnf, apk), includes a 7-step orchestrator with rollback, a security gate for command execution, and 10 built-in profiles for different dev stacks. The tool also handles WSL2 setup, dotfiles, encrypted vaults, and Distrobox containers.

• •Nexus is a static Go binary that provisions dev environments via declarative YAML profiles across Linux distros and WSL2
• •Includes a 7-step orchestrator with rollback, security gate with allowlist and metacharacter rejection, and 10 built-in profiles
• •Compares favorably against Ansible, Nix, and chezmoi on binary portability, security, rollback, and WSL2 support
