Privacy-first JSON editing — local processing with a minimal backend
Developers often work with API responses, configuration files, and test data that can include sensitive values — API keys, user identifiers, or internal references. That makes privacy an important consideration.
“PrettyJson.site is designed so your JSON never needs to leave your browser. We process formatting, validation, sorting, and conversions locally.”
How PrettyJson.site handles your JSON
All core JSON operations — beautify, minify, validate, compare, and convert — run entirely in the user’s browser. That means the JSON you paste or upload is used only by client-side code.
Backend usage
PrettyJson.site does have a lightweight backend, but it is not used to receive, process, or store editor JSON. The backend only supports:
- Receiving user feedback and feature requests
- Serving static site files and updates
- Minimal, opt-in analytics to improve the product
Privacy-first workflow benefits
Performing all operations locally keeps your data private and secure. This approach ensures:
- JSON remains on your device
- Immediate processing without server communication
- Reduced exposure risk for sensitive data
Practical examples
- API debugging: Format and inspect responses safely.
- Configuration files: Work with DevOps manifests securely.
- Customer data: Analyze test payloads locally without exposing private info.
Extra safety tips
- Use browser offline mode or an isolated profile for extremely sensitive JSON.
- Redact secrets before pasting, even in PrettyJson.site.
- Maintain local backups and version control for critical files.
Final thoughts
PrettyJson.site gives developers a fast, friendly JSON editor that respects privacy by default. Core features run entirely in the browser, while the minimal backend only supports feedback and site updates.
