How I tested the best AI coding agents
I focused on real-world developer pain points.
1. Setup + onboarding
Testing how quickly each tool integrates with IDEs.
2. Code execution and accuracy
Evaluating the ability to write production-ready code across languages.
3. Workflow flexibility
Searching for agents that assist with multi-file edits.
What are AI coding agents?
These tools help you write, understand, and manage code fast.
What to look for in agent-style dev tools
- Autonomy: They should handle tasks like refactoring and generating test suites.
- Context: They remember your codebase and project structure.
- Tooling: Integration is critical with tools like GitHub and Jira.
- Auditability: Quality agents let you monitor actions and review changes.
Common pain points of AI agents
- Over-relying on AI-generated code without human review.
- Choosing a tool that can’t be customized.
- Lack of observability without logging.
