Our Mission

Public Internet exists to demonstrate that the web can be different. We believe useful tools should be free, instantly accessible, and respectful of your privacy. No login walls. No data harvesting. No dark patterns. Just tools that work.

We're building an alternative to the cluttered internet where every free tool requires email signups or premium paywalls. Public Internet proves there's a better way.

What We Offer

Calculators: Financial, fitness, math, time, and specialized calculators for every need.

Converters: Units, formats, data types, and specialized conversion tools.

Developer Tools: JSON, JWT, schema generators, cron translators, and utilities for developers.

Design Tools: Color generators, gradient builders, pattern creators, and visual utilities.

Games: Browser-based games for when you need a break, all running instantly.

Network Tools: IP utilities, QR codes, checksums, and networking helpers.

Our Commitment

  • Accuracy: We test every tool against established standards and formulas
  • Speed: No bloat, no frameworks, vanilla HTML/CSS/JavaScript for instant performance
  • Accessibility: Works on desktop, tablet, and mobile with any modern browser
  • Open: Built with web standards, no proprietary formats or vendor lock-in
  • Privacy: All tools run 100% in your browser with zero server-side processing
  • Simplicity: One click to use any tool. No friction, no friction, no friction.

Built on the Open Web

Public Internet is built entirely with web standards: HTML, CSS, and JavaScript. We don't use heavy frameworks or proprietary technologies. This means:

  • Fast loading, even on slow connections
  • Small bundle size, respectful of your bandwidth
  • Offline capable once loaded
  • Progressive enhancement and wide browser support
  • Source-friendly and auditable code
