How to evaluate AI coding tools
Use a real bug, a small feature, and a test-writing task. Measure not just generated lines but correctness, maintainability, security, and how much review is required.
Prototype tools versus engineering assistants
Prototype tools help validate ideas quickly. Engineering assistants are better when you already have a codebase, tests, conventions, and production requirements.
How to test these tools
- Pick one real workflow you repeat weekly.
- Run the same input through two or three tools.
- Score output quality, review time, factual accuracy, collaboration, privacy, and price.
- Adopt the winner only if it saves time after human review.
FAQ
Can AI coding tools ship production code alone?
No. They can accelerate implementation, but production work still needs human engineering review, tests, security checks, and deployment discipline.
Which coding tool is best for non-developers?
Lovable, Bolt.new, and Replit AI are better starting points for non-developers than repo-first coding assistants.
