OpenBug CLI is an intelligent command-line tool designed for real-time debugging of running applications using AI assistance. It allows developers to run commands, view logs, and receive AI-powered insights within a single interactive terminal interface, eliminating the need to switch between different tools during debugging sessions.

The tool captures logs automatically from running applications and enables natural language search across your codebase. It provides multi-service debugging capabilities, allowing you to debug across your entire stack simultaneously. OpenBug coordinates debugging agents that analyze what's actually happening when your code runs, providing insights based on runtime behavior rather than static analysis.

OpenBug works by starting an AI assistant that connects to a local cluster server. When you run commands with the debug prefix, your services stream logs to the cluster while the AI server processes queries, searches code, and analyzes logs through an Agent Graph. The system uses WebSocket connections to maintain real-time communication between your local environment and the AI processing backend.

The primary benefit is eliminating context-switching between logs and code during debugging sessions. Developers can ask questions like "why is the auth endpoint failing?" and receive answers based on actual runtime logs combined with relevant code from their codebase. It's particularly useful for debugging across multiple services and understanding unfamiliar codebases through natural language queries.

OpenBug targets developers working with running applications who need to debug complex issues across multiple services. It integrates with various development workflows through command-line usage and supports self-hosting options for organizations with specific security requirements.
