Zero-Persistence Relay Starter

$199

WebSocket relay that never touches disk. Stateless by design.

The complete relay service from apps/relay/ — standalone, documented, and ready to deploy. Includes quota manager, room manager, API key rotation with zero-downtime grace slots, and metrics server. ESLint rules, strace CI, and readonlyRootFS config enforce zero persistence.

• In-memory quota enforcement by tier
• Tenant-isolated room namespacing
• HMAC API key issuance and rotation (2-slot)
• Metrics HTTP server (internal)
• ESLint rules enforcing zero-persistence
• Dockerfile with healthcheck + non-root
• Stress tests (10k connections, 1k rooms)
