Why We Created Royalty

We believe consumers deserve to know when they're being overcharged. Online retailers often use dark patterns and dynamic pricing to maximize profits at your expense.

Many existing price comparison tools are themselves for-profit companies with hidden agendas and undisclosed partnerships with retailers.

Royalty was built to be different - a community-driven tool that puts consumers first and remains transparent about everything we do.

Our Pledge to Users:

  • We will always be 100% open source
  • We will never sell your personal data
  • We will not prioritize results based on partnerships
