Lightweight WebSocket networking for browser games. Rooms, relays, host management, tags, and binary — all in one dependency-free ES module.

→ Room creation, joining, and host handoff
→ Broadcast relay or direct player messaging
→ Binary ArrayBuffer support for fast position sync
→ Tags & metadata for lobby filtering
→ Zero dependencies — just drop in and go

Cascade

Self-hosted AI middleware that routes prompts across free providers — Gemini, Groq, Mistral, and Cerebras. One endpoint, automatic fallback, always an answer.

→ Difficulty float maps to a model tier automatically
→ Climbs to smarter models on complexity, falls back on failure
→ Key rotation — pipe-separate multiple keys per provider
→ Origin whitelist, rate limiting, and per-request timeout
→ Deploy free to Render in minutes
