npm install -g flexgate-proxy
flexgate init # generates config/flexgate.json

flexgate start # starts gateway on :3001, Admin UI on :3000FlexGate is a production-grade reverse proxy and API gateway built on Node.js. It sits in front of your upstream services and gives you intelligent traffic control, real-time observability, and AI-native incident response — all in one package.
Stop copy-pasting logs into Claude. FlexGate emits 10 structured event types (CIRCUIT_BREAKER_OPENED, HIGH_LATENCY, ERROR_RATE_SPIKE, ...) that AI agents can reason about directly — no dashboards, no noisy logs.
SSRF protection, HMAC-SHA256 API keys, tiered rate limiting (global / admin / auth), restricted CORS via ALLOWED_ORIGINS, and 0 npm vulnerabilities.
Per-upstream circuit breaking with configurable thresholds and automatic recovery. Exponential backoff retries with jitter. Never let one bad upstream take down everything.
Prometheus metrics, Winston structured JSON logs, Server-Sent Events for live dashboard streaming, and full PostgreSQL persistence for every request.
Full React dashboard built-in: manage routes, webhooks, logs, metrics, settings, and AI incidents from a single URL at http://localhost:3000.
~$5/day for AI-assisted incident response vs $50–500/day for Grafana + PagerDuty + on-call. Clean, pre-digested signals mean fewer tokens and less hallucination risk.
