NAME

Coral — The open-source AI debugger for distributed apps. Root cause in seconds, not hours.

SYNOPSIS

coral [command] [options]

DESCRIPTION

Coral is an AI-powered debugger designed for distributed systems. It gives AI assistants “hands” inside your running code by deploying eBPF probes and profiling live code in real-time. Unlike traditional observability tools, Coral is optimized for live investigation, allowing you to ask why a service is behaving a certain way rather than just seeing that it is.

CORE CAPABILITIES

  • Zero Instrumentation: Works on running services via eBPF with no code changes required.
  • AI-Powered Analysis: Returns root causes instead of raw metrics for LLM-driven troubleshooting.
  • Deep Profiling: On-demand CPU and memory profiling with flame graphs (<1% overhead).
  • Service Awareness: Indexes binaries to locate symbols and functions even without exact names.

EXAMPLES

Ask the AI to diagnose a latency spike:

$ coral ask "Why is the payment API slow?"

Analyze memory growth in a specific worker:

$ coral ask "Why is the order-processor using 10GB of RAM?"

ARCHITECTURE

Coral follows a decentralized architecture where agents collect telemetry and the Colony acts as a control plane/MCP server.
