## The Hidden Cost of Centralized SaaS

Traditional SaaS architectures force developers to route every byte of data through cloud servers. This introduces latency, subscription tax, and privacy vulnerabilities.

When building AI leverage tools, centralizing user API keys requires heavy compliance overhead, expensive database encryption infrastructure, and constant security audits.

## The Local-First Alternative

By keeping compute and state on the client side:

- **Cost drops to zero**: No backend server fees for data storage or key management.
- **Privacy by default**: Data remains on the user's hardware.
- **Instant response**: Zero round-trip latency to remote key servers.
