Quickstart & Multi-Platform Installation

Nuncio is 100% free, sovereign, and open-source under MIT & Apache-2.0 licenses. Choose your target platform below for instant setup.

Option 1: macOS & Linux via Homebrew Tap

The fastest way to install Nuncio CLI, TUI, MCP, and daemon binaries on macOS and Linux is using our official Homebrew tap:

# Add tap and install all Nuncio workspace binaries
brew tap koftwentytwo/tap
brew install nuncio

Option 2: Cargo Rust Crates (Cross-Platform)

If you have the Rust toolchain installed, build and install directly from crates.io with native CPU optimizations:

cargo install nuncio-cli nuncio-tui nuncio-mcp nunciod

Daemon Auto-Spawning & IPC IPC Architecture (`nunciod`)

Nuncio operates on a zero-configuration hybrid daemon architecture. Launching any presentation interface (`nuncio`, `nuncio-tui`, `nuncio-gui`, `nuncio-mcp`) automatically auto-spawns `nunciod` in the background. All presentation shells share a single-writer SQLite WAL database instance with zero race conditions.
