OneUptime: The Open‑Source All‑In‑One Monitoring, Alerting & Incident‑Response Platform

The hidden cost of “free” monitoring

Every modern service—whether a tiny hobby API or a global SaaS platform—needs reliable uptime monitoring. Yet most teams reach for the first‑click SaaS offering (Pingdom, UptimeRobot, Statuspage.io, PagerDuty…) and end up paying recurring fees, surrendering data to third‑party vendors, and wrestling with feature gaps that force workarounds.

What if you could own the entire monitoring stack, keep every metric and incident log on‑prem, and still enjoy a polished UI, rich integrations, and a vibrant community? That’s exactly the problem OneUptime solves.

OneUptime is an open‑source, self‑hosted platform that bundles website & API monitoring, synthetic checks, log aggregation, alert routing, status pages, and incident management into a single, cohesive system. It’s built on a modern stack (Node.js, TypeScript, React, PostgreSQL, Docker) and can be deployed on a single server or scaled across a Kubernetes cluster.

Getting Started with OneUptime

Below is a quick path to spin up a fully functional instance on your local machine using Docker‑Compose. The same repository also provides Helm charts for Kubernetes clusters.

Prerequisites

• Docker ≥ 20.10
• Docker‑Compose ≥ 2.0
• (Optional) git for cloning the repo

1️⃣ Clone the repository

git clone https://github.com/OneUptime/oneuptime.git
cd oneuptime

2️⃣ Set up environment variables

Copy the sample .env.example to .env and adjust any values you need (e.g., POSTGRES_PASSWORD, BASE_URL).

cp .env.example .env
# Edit .env with your favorite editor

3️⃣ Launch the stack

docker compose up -d

Docker will pull the necessary images (backend, frontend, PostgreSQL, Redis, etc.) and start them in the correct order. The first run may take a few minutes while the database initializes.

4️⃣ Access the UI

Open your browser and navigate to http://localhost:3000. The default admin credentials are:

• Email: [email protected]
• Password: admin123

⚠️ Security tip: Immediately change the default password and configure HTTPS (via a reverse proxy like Nginx or Traefik) before exposing the service to the internet.

5️⃣ Add your first monitor

1. Click Monitors → New Monitor.
2. Choose a protocol (e.g., HTTP), fill in the target URL, set the interval, and save.
3. Define an alert channel (e.g., Slack webhook) under Alerts → Notification Channels.

That’s it—OneUptime will now ping your endpoint, record uptime percentages, and fire alerts when thresholds are breached.

For a more detailed walkthrough, see the official Getting‑Started guide: OneUptime Docs – Getting Started.

OneUptime vs. Proprietary Alternatives

Bottom line: If you’re already paying for multiple SaaS tools to cover monitoring, alerts, status pages, and incident response, OneUptime can replace them all with a single, cost‑neutral deployment—while giving you full control over data and customization.

Community, Support, and Roadmap

OneUptime’s development is driven by a global community of SREs, DevOps engineers, and hobbyists. The project follows a transparent GitHub Issues + Discussions workflow:

• Feature Requests – Vote on upcoming features via the “Reactions” on issues.
• Bug Reports – Tag with bug and include logs; maintainers respond within 48 hours on average.
• Contributing – Fork, submit PRs, and run the built‑in CI (GitHub Actions) that validates TypeScript, Docker builds, and integration tests.

The roadmap (as of 2025) includes native Grafana dashboards, AI‑driven anomaly detection, and edge‑node monitoring for distributed IoT fleets.
