  • ✕Frequent server downtime and rate-limiting queues

Detailed Architectural Differences

Zero-Knowledge Security Architecture

In client-side applications, the web server only delivers static HTML, CSS, and compiled JavaScript/Wasm bundles. Once loaded, calculations occur exclusively in browser RAM, ensuring zero-knowledge security.

Network Independence & Scalability

Client-side web tools scale infinitely without server degradation because each user provides their own computational power, guaranteeing zero downtime during peak traffic spikes.
