🚀 Installation

Linux (Debian/Ubuntu)

Download and install the .deb package:

# Download the latest .deb package from releases
wget https://github.com/PlebOne/nos/releases/latest/download/nos_1.1.9_amd64.deb

# Install the package
sudo dpkg -i nos_1.1.9_amd64.deb

# If you encounter dependency issues, run:
sudo apt-get install -f

Alternative architectures:

• ARM64: nos_1.1.9_arm64.deb
• ARMv7: nos_1.1.9_armhf.deb

Linux (Snap Store)

Install from the Snap Store:

sudo snap install nos

The snap package provides automatic updates and works across all major Linux distributions.

Windows (Recommended)

Install via Microsoft winget (Windows Package Manager):

winget install PlebOne.nos

Note: If you encounter a security warning during winget installation, this is because the executable is not yet code-signed. You can:

1. Alternative method: Download manually from releases and run:

   # Download the .exe file, then:
   Unblock-File -Path "path\to\nos-VERSION-windows-amd64.exe"

2. One-liner install (PowerShell as Administrator):

   Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/PlebOne/nos/main/install.ps1'))

Code signing is being implemented to resolve this issue permanently.

Manual Download

Download the latest release for your platform from the releases page:

• Windows: Download nos-VERSION-windows-amd64.exe or nos-VERSION-windows-arm64.exe
• Linux: Download nos_VERSION_linux_amd64.tar.gz or nos_VERSION_linux_arm64.tar.gz
• macOS: Download nos_VERSION_darwin_amd64.tar.gz or nos_VERSION_darwin_arm64.tar.gz

Windows users: After downloading, right-click the .exe file → Properties → Check "Unblock" if present.

Using Go

go install github.com/PlebOne/nos@latest

Build from Source

git clone https://github.com/PlebOne/nos.git
cd nos
go build -o nos
# Linux/macOS: sudo mv nos /usr/local/bin/
# Windows: move nos.exe to a directory in your PATH

Usage

Interactive Menu Mode

Simply run nos without any arguments to enter the interactive menu:

nos

This opens a beautiful menu-driven interface where you can:

• Setup your account (add nsec)
• Post messages
• Verify your posts on relays
• Manage relays
• Reset your account

Quick Command Mode

For faster posting, you can use command-line arguments or stdin:

# Post a message directly
nos "Hello Nostr world!"

# Post from stdin (best for hashtags and URLs)
echo "Check out #bitcoin at https://bitcoin.org" | nos

# Multi-line posts with stdin
echo "Line 1
Line 2
#hashtag https://example.com" | nos

# Using PowerShell (Windows)
"My #nostr post with https://example.com" | nos

💡 Tip: Use stdin (echo "message" | nos) when your message contains special characters like hashtags (#) or URLs, as it avoids shell escaping issues.

First Time Setup

The first time you post, nos will prompt for your nsec (private key):

nos "My first post"
# Will prompt: "Enter your nsec key (starts with nsec1):"

Verifying Your Posts

Check if your posts are visible on relays:

nos verify

This will:

• Show your npub (public key)
• Connect to each relay and check for your recent posts
• Display a summary of posts found on each relay

Managing Relays

Customize which relays to use through the interactive menu or commands:

# Interactive relay management
nos relay

# Or use direct commands:
nos relay list                      # List current relays
nos relay add wss://relay.example.com    # Add a new relay
nos relay remove wss://relay.example.com # Remove a relay
nos relay reset                     # Reset to default relays

Changing Accounts / Reset

To completely reset nos and change to a different Nostr account:

nos reset

This will:

• Delete your stored nsec key
• Remove any custom relay configuration
• Allow you to set up nos with a different account

Security

Your nsec key is stored securely using your system's native keyring:

• Linux: Secret Service API (GNOME Keyring, KWallet)
• macOS: Keychain
• Windows: Windows Credential Manager

Default Relays

The client posts to these relays by default:

• wss://relay.damus.io
• wss://nos.lol
• wss://relay.nostr.band
• wss://relay.current.fyi
• wss://relay.snort.social
• wss://relay.primal.net
