# Deploy and Host uptime-kuma on Railway

Deploy **Uptime Kuma** on Railway in under 60 seconds with this one-click template. Get a production-ready, self-hosted monitoring dashboard with automatic SSL, persistent storage, and zero infrastructure management. This template uses the official louislam/uptime-kuma:1 Docker image and provisions everything you need to monitor your services, websites, and APIs from a single elegant interface.


## About Hosting uptime-kuma

Uptime Kuma is an open-source, self-hosted monitoring tool that tracks the availability and performance of your web services, APIs, servers, and Docker containers. Created as a modern alternative to commercial uptime monitors, it combines powerful monitoring capabilities with an exceptionally clean UI that developers actually enjoy using.


**Key Features:**
- **Multi-Protocol Monitoring** — HTTP(s), TCP, ping, DNS, WebSocket, Docker containers
- **90+ Notification Integrations** — Uptime Kuma provides Discord, Slack, Telegram, email, webhooks via Apprise
- **Public Status Pages** — Share uptime dashboards with clients or teams
- **Lightweight Architecture** — Runs on SQLite, requiring minimal resources (512MB RAM)
- **Push Monitors** — Heartbeat endpoints for cron jobs and scheduled tasks
- **Certificate Monitoring** — Track SSL/TLS expiration automatically
- **Two-Factor Authentication** — Secure your dashboard with 2FA
- **Prometheus Metrics** — Export data via `/metrics` endpoint

Single Node.js application with embedded SQLite stored at `/app/data` — your entire monitoring configuration lives in one file.

## Common Use Cases of Uptime Kuma

- **SaaS monitoring** — Track production API endpoints with Discord/Slack alerts and a public `status.yourapp.com` page
- **Home lab** — Monitor Plex, Nextcloud, Home Assistant, and internal IPs that external SaaS tools cannot reach
- **Client websites** — Agencies monitoring dozens of client sites from one dashboard with per-client status pages
- **Cron job health checks** — Push monitors alert you when nightly backups or scheduled tasks silently fail
- **SSL expiration tracking** — Catch certificate expiry before it causes outages
- **Internal API monitoring** — Monitor private endpoints over Railway's internal network without public exposure
- **Database connectivity** — TCP port checks on PostgreSQL/Redis without exposing credentials


## Dependencies for Uptime Kuma Hosting

Uptime Kuma is entirely self-contained with zero external dependencies. The embedded SQLite database eliminates the need for PostgreSQL, MySQL, or Redis.

### Deployment Dependencies

**Minimum requirements:** 512MB RAM, 1GB persistent storage, single vCPU. No external services required.


### Adding an HTTP(S) monitor:

```javascript
// Example: Monitoring a REST API endpoint
Monitor Type: HTTP(s)
Friendly Name: Production API Health
URL: https://api.yourapp.com/health
Heartbeat Interval: 60 seconds
Retries: 3
Accepted Status Codes: 200-299

// Advanced settings
Request Method: GET
Request Headers:
  Authorization: Bearer your-api-key
  User-Agent: UptimeKuma/1.0

Expected Response:
  {"status":"healthy"}
```

### Creating Public Status Pages in Uptime Kuma

Status pages transform Uptime Kuma from an internal tool into a customer-facing communication channel. Navigate to **Status Pages** in the sidebar and click **New Status Page**.

**Configuration example:**

```yaml
# Status page settings
Title: "MyApp System Status"
URL Slug: /status
Description: "Real-time status of MyApp services"

# Monitor groups
Groups:
  - Name: "Core Services"
    Monitors:
      - Production API
      - Authentication Service
      - Database Primary
  
  - Name: "CDN & Assets"
    Monitors:
      - CloudFront Distribution
      - S3 Bucket Availability
```

### Notification Configuration

Uptime Kuma's notification system uses **Apprise**, supporting 90+ services through a unified interface. Configure notifications in **Settings → Notifications**.

**Email via SMTP:**

```
Notification Type: SMTP (Email)
Friendly Name: Admin Alerts

Host: smtp.gmail.com
Port: 587
Security: TLS
Username: alerts@yourapp.com
Password: your-app-password
From Email: alerts@yourapp.com
To Email: admin@yourapp.com, oncall@yourapp.com

Custom Subject: [ALERT] {monitor.name} is {monitor.status}
```

**Notification strategies:**
- **Critical services:** Multiple channels (Discord + Email + SMS)
- **Non-critical services:** Single channel with grouped alerts
- **Maintenance windows:** Temporarily disable notifications to prevent alert fatigue

Configure **notification groups** to avoid duplicate alerts when multiple monitors fail simultaneously—useful when a network outage affects several services.

### Backup and Data Persistence

Your entire Uptime Kuma configuration lives in `/app/data/kuma.db`, a single SQLite file. Railway's persistent volumes ensure this survives container restarts, but you should implement additional backups for disaster recovery.

## Why Deploy Uptime Kuma on Railway

Railway transforms Uptime Kuma deployment from a 15-minute Docker configuration exercise into a single click.

**Automatic HTTPS** — SSL certificates and reverse proxy handled automatically. No Nginx, no Caddy, no Let's Encrypt renewals.

**Persistent Volumes** — Monitoring data survives container restarts automatically. No Docker volume syntax to remember.

**Zero-Downtime Deployments** — Health checks ensure new containers are ready before traffic switches over.

**$5 Free Credit Monthly** — Uptime Kuma's tiny resource footprint means the free tier covers small-to-medium workloads indefinitely.

**Private Networking** — Monitor other Railway services via private network addresses without public exposure.

Compared to a DigitalOcean VPS, you eliminate firewall setup, reverse proxy configuration, SSL management, and Docker Compose maintenance entirely.

## Uptime Kuma vs Competitors

### Uptime Kuma vs UptimeRobot

UptimeRobot's free tier caps at 50 monitors with 5-minute check intervals. Uptime Kuma gives you unlimited monitors at 20-second intervals. The decisive difference: UptimeRobot runs from external servers and cannot reach internal services, private IPs, or localhost. Uptime Kuma can monitor anything your Railway deployment can reach. UptimeRobot paid plans start at $7/month — Uptime Kuma on Railway's free tier costs nothing.

### Uptime Kuma vs Prometheus + Grafana

Prometheus + Grafana are powerful but require deploying and maintaining multiple services, configuring exporters, and writing PromQL. Uptime Kuma is a complete solution in a single container with a UI non-technical stakeholders can read instantly. They're not mutually exclusive — Uptime Kuma exposes a `/metrics` endpoint so you can scrape uptime data into Prometheus for unified observability.

### Uptime Kuma vs Better Uptime / Statuspage.io

Commercial status page tools charge $20-$100/month for features Uptime Kuma provides free. The trade-off is global monitoring locations (checking from multiple continents) and dedicated support, which commercial tools offer. For most teams, Uptime Kuma's self-hosted approach wins on cost and privacy.

### Uptime Kuma vs Statping-ng

The closest open-source alternative, but Statping development has been inconsistent. Uptime Kuma has more active development, better documentation, and significantly more notification integrations (90+ vs ~20). GitHub star count and contributor activity both favour Uptime Kuma by a wide margin.

## FAQ

**Is Uptime Kuma truly free and open source?**
Yes — MIT licensed, no usage limits, no licensing fees. Actively maintained at `louislam/uptime-kuma` with 50,000+ GitHub stars.

**Can Uptime Kuma monitor internal services not publicly accessible?**
Yes, this is its key advantage over SaaS tools. It can reach private IPs, localhost, internal APIs, and Railway private network addresses — anything the host can reach.

**What happens to monitoring data if Railway has an outage?**
Data is stored in Railway's persistent volumes. Checks pause during any outage, but historical data is preserved. 

**How many monitors one instance of Uptime Kuma can handle?**
512MB RAM handles 50–100 monitors at 60-second intervals comfortably. Increase to 1GB for 200+ monitors or 20-second intervals. SQLite remains performant well beyond 500 monitors, though the UI gets unwieldy at that scale.

**Can I migrate from UptimeRobot?**
No native import tool exists, but Uptime Kuma's API allows scripting monitor creation from exported CSV data for large deployments.

**Does Uptime Kuma support team access?**
Multiple user accounts with admin/non-admin roles are supported. Granular per-monitor permissions are not currently available — all authenticated users see all monitors.
