The AI Coding Agents That Finally Move from Demo to Production

AI coding agents have matured beyond sandboxes to become production-ready tools that integrate with real Git workflows, run actual test suites, and understand when to ask for human approval before critical actions.

This analysis separates production-ready tools from demos by evaluating their ability to handle unfamiliar codebases and work within your actual development lifecycle.
