Ninjap 🥷

Promote someone to Ninja. Instantly.

Ninjap is a lightweight Ruby gem that generates beautiful PNG certificates to officially promote someone to Ninja status.

It can be used:

• From the command line
• Inside Ruby applications
• As part of web services (like https://smokyusmaximus.com)

• Generate PNG certificate files
• Clean CLI interface
• Lightweight (MiniMagick based)
• No heavy dependencies
• Perfect for fun promotions, internal awards, or creative projects

Add this line to your application's Gemfile:

gem 'ninjap'

Then run:

bundle install

Or install directly:

gem install ninjap

Promote someone directly from terminal:

ninjap -p "Great Person" "Your Name" output.png
