Why We Replaced Cloud Geojson Geometry Redactor - Merchant Privacy & Data Utility with Zero-Egress WebAssembly & Client-Side Local RAM

In modern web development, countless daily utility tasks needlessly upload sensitive user data to unverified SaaS servers.

The Problem

When engineering teams format confidential JSON, inspect Brotli archives, or sanitize customer datasets, data exfiltration becomes a serious compliance hazard.

The Architecture

To eliminate this attack surface, Geojson Geometry Redactor - Merchant Privacy & Data Utility was architected around pure client-side execution:

• Zero Cloud Ingestion: Computations execute entirely in local browser memory via WebAssembly & Client-Side Local RAM.
• Air-Gapped Operation: No background telemetry, no tracking pixels, zero analytics egress.
• Micro-Engine: Instant sub-second response without subscription paywalls.

Live Browser Sandbox

You can verify the client-side execution and inspect memory isolation in the live sandbox:
