gatus

Gatus is a self-hosted status page and health monitoring dashboard written in Go. It continuously checks the health of your services via HTTP, TCP, DNS, ICMP, and other protocols, then alerts via Slack, PagerDuty, Teams, Discord, and 40+ other integrations when issues are detected.

What gatus is

Go-based monitoring tool that executes configurable health checks against endpoints, evaluates results using condition expressions, stores metrics, and exposes both a web dashboard and Prometheus-compatible metrics endpoint. Supports multiple transport protocols, custom alerting rules, and can be deployed as a container or binary.

Quickstart

Get the gatus source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/TwiN/gatus.gitcd gatus# follow the project's README for install & configuration

Best use cases

Proactive service monitoring before customer impact

Continuously health-check your APIs, microservices, and infrastructure endpoints independent of production traffic. Detect failures immediately and alert teams before clients are affected, unlike metrics-based systems that rely on existing traffic.

Internal or customer-facing status pages

Display real-time health status of services to internal teams or public customers. Built-in dashboard shows service uptime, response times, and incident history with minimal setup required.

Multi-protocol endpoint monitoring

Monitor diverse endpoint types (HTTP, TCP, DNS, ICMP, gRPC, WebSocket, TLS/STARTTLS) and certificate expiration in a single tool. Useful for heterogeneous infrastructure with databases, message queues, load balancers, and APIs.

Implementation considerations

  • Storage backend: default is in-memory or file-based; production use should integrate persistent storage (PostgreSQL, MySQL, SQLite) for metrics and incident history.
  • Configuration is YAML-based with environment variable substitution; keep endpoint definitions modular to avoid large monolithic config files.
  • Alert latency and check frequency trade-off: default intervals are documented (FAQ section); tune based on tolerance for false positives vs. detection speed.
  • Authentication: basic auth and OIDC are supported; plan identity provider integration if exposing dashboard to multiple teams.
  • Scaling: single instance is the standard deployment; requires manual sharding or external load balancing for very high check volumes.

When to avoid it — and what to weigh

  • Require managed SaaS with guarantees — Gatus is self-hosted only. If you need vendor-managed uptime SLAs, support contracts, and multi-region redundancy out of the box, consider Datadog, New Relic, or Pingdom.
  • Need complex log aggregation or metrics correlation — Gatus focuses on endpoint health checks and alerting, not log analysis or deep metrics correlation. Use ELK, Splunk, or Datadog for forensics and analytics.
  • Limited Kubernetes or containerization experience — While Docker images are provided, production deployment (HA, storage backend, cert management, networking) requires container infrastructure knowledge. Simpler alternatives exist for non-containerized environments.
  • Need enterprise support or security audit trail — Project is community-maintained; no commercial support, SLA, or formal security audit process documented. Not suitable for regulated industries requiring vendor accountability.

License & commercial use

Apache License 2.0 (Apache-2.0), a permissive OSI-approved license. Permits commercial use, modification, and distribution with proper attribution.

Apache-2.0 is a permissive open-source license that allows commercial use. However, the project is community-maintained with no paid support, SLA, or vendor warranty. Ensure your legal and security teams review license obligations (e.g., NOTICE file, liability disclaimers) before production use in commercial environments.

Security considerations

Project does not claim to have undergone formal security audit. Basic authentication and OIDC are available for dashboard access; configure TLS for all endpoints. Secrets (API keys, webhooks) are passed via environment variables or config files—implement proper secret management (e.g., Kubernetes Secrets, HashiCorp Vault). No documented vulnerability disclosure process; review open issues for reported concerns.

Alternatives to consider

Prometheus + Alertmanager + Blackbox Exporter

More mature, widely adopted metric-based monitoring. Requires more setup but integrates deeply with observability stacks. Better for metrics-driven alerting.

Datadog Synthetics / New Relic Synthetic Monitoring

Managed SaaS with vendor support, multi-region execution, and deep analytics. Eliminates operational overhead; suitable for regulated industries.

Uptime Robot / Pingdom

Simple, managed status monitoring for non-technical users. No self-hosting overhead; suitable for SMBs without DevOps capacity.

gatus FAQ

Can Gatus detect problems if no one is accessing the service?
Yes. Unlike metrics-based systems (Prometheus, Cloudwatch), Gatus proactively pings endpoints on a schedule independent of production traffic, so you are alerted before customers notice issues.
What is the recommended health-check interval?
Documentation states default timeouts are documented in FAQ; choose interval based on tolerance for latency before detection. Typical values are 30–60 seconds for critical services.
Is there a managed/SaaS version of Gatus?
Yes, Gatus.io offers a managed solution, but the open-source project is self-hosted only.
Can I use Gatus in production without external storage?
Yes, but with limitations: in-memory or file-based storage is sufficient for small deployments. For high-traffic or multi-instance setups, external database (PostgreSQL, MySQL) is recommended.
