Ephimero (MVP)

A private P2P communication experiment. (Yes. A chat. Groundbreaking, I know.) Deterministic identity via SHA-256. No accounts. No databases. No server memory of your existence. Just you, your peer, and the ephemeral magic of WebRTC.

Engineering Uptime Without Paying

SYSTEM DESIGN

-How Ephimero Stays Awake-

Ephimero started as a lightweight WebRTC signaler for secure P2P chat. Free-tier hosts sleep after inactivity, so I engineered a zero-cost worker + telemetry system. Observability, retention, and self-pruning all included.

• Redis (30MB constraint)
• Timestamp-based eviction
• FastAPI orchestration layer

• Self-triggering worker
• 7 days rolling telemetry
• Zero USDs uptime strategy
