Why I Built These Tools

While building backend systems and features, I constantly found myself needing small utilities.

Most available tools online were:

  • slow and clunky
  • overloaded with unnecessary features
  • hidden behind paywalls
  • collecting user data

So I started building my own minimal developer utilities focused entirely on:

  • speed
  • privacy
  • simplicity

Unless interacting with third-party APIs, the tools on these pages run directly in your browser.
