2026 Coding Agent Benchmark: Claude Code vs Cursor vs Copilot vs Devin
Contents
Testing Method
10 real programming tasks:
- Simple functions (3): write a utility function, data transformation
- Medium complexity (4): implement an API, design a module
- Hard algorithms (3): complex data structures, concurrency, performance optimization
Evaluation criteria:
- Completion rate: can independently complete task (no human input)
- Code quality: correctness, readability, optimality
- Time: average time from task to completion
- Cost: monthly fee + API consumption
