Not all coding agents solve the same problem
Cursor is strong in editor and cloud-agent workflows, GitHub Copilot fits issue-to-PR loops, Claude Code is practical in terminal and repository context, and Qwen Code opens the door to open-model routing. The question is not which is best, but which role the agent should play in your team.
How to compare tools
Useful criteria: whether the agent runs tests, opens PRs, works in isolation, has tool permissions, exposes traces, supports model choice and keeps data in an acceptable jurisdiction. Without these criteria, comparison becomes opinion.
The WebEdge workflow
Start with small tasks: documentation, test additions and simple bug fixes. Then add CI, security scan, database branch and human review. Only after that should an agent receive larger refactoring tasks.
