JSON Copilot What does "client-side processing" mean?
Privacy & Security
"Client-side processing" means all JSON operations happen directly in your web browser - on your device - rather than being sent to a remote server. This is the foundation of JSON Copilot's privacy-first architecture.
Your Data Never Leaves Your Device
When you paste, edit, format, or validate JSON in JSON Copilot, it's processed entirely within your browser. No uploads, no servers, no third parties.
How It Works
Browser-Based Engine
JSON Copilot runs 100% in your browser using JavaScript. All formatting, minification, validation, and tree view generation happens on your device's CPU.
No Network Requests
Your JSON content is never transmitted over the network. Open your browser's Network tab - you'll see zero requests when processing JSON.
Instant Results
Because everything runs locally, operations are instant - no waiting for server responses or dealing with network latency.
Client-Side vs Server-Side
Client-Side (JSON Copilot)

- ✗ Privacy concerns
- ✗ Upload size restrictions
- ✗ May require payment
Security & Privacy Benefits
No Data Leaks
Since your JSON never leaves your browser, there's zero risk of data leaks, breaches, or unauthorized access.
GDPR Compliant
Client-side processing means we don't collect or store your data - perfect for GDPR compliance.
No Logging
We can't log what we never see. Your JSON content is never accessible to us or any third party.
Sensitive Data Safe
Work confidently with API keys, credentials, or proprietary data - it stays on your device.
Verify It Yourself
Don't take our word for it! Open your browser's Developer Tools → Network tab while using JSON Copilot. You'll see that formatting, minifying, and validating JSON produces zero network requests.
Note on AI Features
While core JSON operations are 100% client-side, AI-powered features (when used) do require sending data to AI providers. These features are clearly labeled and optional.
