I built Easemonitor to keep track of service uptime, response times, SEO, vulnerability scans, etc. It's 100 % open‑source (GPL‑3), runs in Docker on a cheap VPS and includes:

NestJS API + worker with BullMQ queues NextJS frontend with SSR caching & image optimization Prometheus metrics, Loki logs, Grafana dashboards, Jaeger tracing JWT rotation, WAF rules, CSP/HSTS, CVE audit scripts Webhook DLQ, queue dashboard, healthchecks, maintenance mode You can try it on my demo https://easemonitor.com

Would love feedback, contributions, or ideas for features.
