Overview
This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.
WHAT IS UPTIME KUMA
Uptime Kuma is a self-hosted uptime and status monitoring tool, shipped as a single Node.js application backed by an embedded SQLite database - a self-hosted alternative to UptimeRobot, Pingdom, and StatusPage that keeps your monitoring data inside your own AWS account. It checks endpoints on a schedule using many monitor types (HTTP and HTTPS, keyword and JSON-query, TCP port, ping, DNS, gRPC, Docker container, and push), records response-time history and uptime percentages, and watches TLS certificate expiry. It raises alerts through 90+ notification integrations including Slack, Telegram, Discord, email/SMTP, webhooks, and PagerDuty, and publishes branded public status pages with incident history and maintenance windows. The web dashboard supports multiple users and is fully MIT licensed - no per-monitor fees, no seat limits, and no vendor lock-in.
WHAT THIS AMI ADDS
Security hardening:
- No admin account baked into the image - the first signup through the one-time setup wizard becomes the owner; there is no default password
- Application bound to 127.0.0.1 only; nginx terminates TLS on 443 and reverse-proxies to it; HTTP redirects to HTTPS
- certbot and the nginx plugin pre-installed - enable a Let's Encrypt certificate with one command
- SQLite state stored under a dedicated data directory with restricted permissions
- UFW firewall - ports 80 and 443 only; SSH on 22
- fail2ban, AppArmor
- CVE scan - every image is scanned for vulnerabilities before release
OS hardening (CIS Level 1):
- CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
- auditd, SSH hardening, Kernel hardening, IMDSv2 enforced
Compliance artifacts:
- SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
- CIS Conformance Report at /etc/lynxroute/cis-report.html
- CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md
Uptime Kuma is an open-source project by Louis Lam. This is an independently packaged, hardened distribution and is not affiliated with or endorsed by the Uptime Kuma project.
Highlights
- Uptime Kuma security baked in: the app bound to localhost behind an nginx TLS proxy on 443, HTTP redirected to HTTPS, and no admin account baked into the image (your first signup becomes the owner) - unlike bare Uptime Kuma AMIs that expose the dashboard directly on port 3001 with no TLS and leave admin signup open to anyone who reaches the URL.
- CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
- Self-hosted UptimeRobot alternative: HTTP, TCP, ping, DNS and keyword monitors, public status pages, response-time and certificate-expiry tracking, and 90+ notification integrations (Slack, Telegram, Discord, email, webhooks). MIT license - fully auditable, no vendor lock-in.

64-bit (x86) Amazon Machine Image (AMI)
Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

- fail2ban, auditd, AppArmor pre-configured

Additional details
Usage instructions
- Launch instance (t3.small recommended)
- Open Security Group - allow TCP 443 from YOUR IP ONLY (important - see note below)
- Open https://<PUBLIC_IP>/ in your browser - accept the self-signed certificate warning
- Complete the one-time setup wizard: create your admin username and password (the first account you create becomes the owner)
- Add your first monitor (HTTP, HTTPS, TCP, ping, DNS, keyword, ...) and watch its status
- Optionally build a public status page and connect notification channels (Slack, email, webhooks)
IMPORTANT: restrict Security Group port 443 to your own IP until you have completed the setup wizard - anyone who reaches the URL before you can claim the admin account. No admin account is baked into the image and there is no default password; the setup wizard auto-locks once the first admin exists. The application listens only on 127.0.0.1:3001 and is reachable only through the nginx HTTPS proxy on 443. Data is stored in an embedded SQLite database on the instance. For production, replace the self-signed certificate: sudo certbot --nginx -d yourdomain.com
