1. Why We Built PrettyJSON

As software engineers handling microservices, REST APIs, and database migrations daily, we grew frustrated with traditional online JSON formatters. Most legacy web tools were bloated with intrusive ads, slow network server roundtrips, vague error messages, and worst of all — uploading private API keys and customer records to remote backend servers.

Our Mission

To provide fast, genuinely private JSON tools that run entirely in your browser, so the data you paste never leaves your device.

3. The Technology Stack

PrettyJSON is built with modern web tooling so it loads quickly and runs entirely in your browser:

  • Built with Angular using standalone components and signals for a responsive interface.
  • Pages are prerendered, so they load fast and are easy for search engines to read.
  • PrimeNG Aura design system for a clean, accessible interface.
  • A built-in JSON auto-repair tool that fixes single quotes, unquoted keys, and trailing commas in the browser.
