Health Engine

ReactEdge Health Engine

ReactEdge Health Engine is an open-source platform for continuously assessing the health of websites and applications.

Rather than focusing on individual metrics, the Health Engine combines observability signals to determine whether a system is healthy, diagnose problems, and recommend or execute safe remediation actions.

Vision

The Health Engine follows a continuous control loop:

Observe
 ↓
Assess
 ↓
Diagnose
 ↓
Remediate
 ↓
Observe

The long-term goal is to provide a vendor-neutral health platform that integrates with existing observability solutions rather than replacing them.

Roadmap

Observe

• Sitemap health verification
• Performance validation
• Cache health
• CPU monitoring
• Platform health scoring

Diagnose

• Root cause analysis
• Agentic diagnosis
• Health recommendations

Remediate

• Rule-based remediation
• Configurable approval workflow
• Automatic recovery for low-risk actions

Principles

• Open source
• Vendor neutral
• Plug & play
• OpenTelemetry-first
• Agent-ready
• Interoperable by design

Status

The project is currently focused on establishing the core Health Engine, beginning with sitemap validation and platform health assessment.
