Cline vs GitHub Copilot in 2026: The Autocomplete vs the Agent

说明与用途

Cline 在多文件任务上更快，完成七文件功能仅需约8分钟，而 Copilot Chat 需要25分钟。Copilot 仍是快速逐行编码的首选。

问题

Choosing the right AI coding assistant for different development scenarios—line‑by‑line typing speed versus multi‑file task automation.

结果

Cline excels at multi‑file, cross‑cutting changes, completing a complex feature in ~8 minutes versus 25 minutes with Copilot Chat and 60 minutes manually. Copilot remains superior for quick line‑by‑line typing with 85 % correct suggestions.

工作流

• 1. Define the multi‑file task (API, service, migration, frontend).
• 2. Run Cline in VS Code to read existing code and plan changes.
• 3. Cline writes and edits files, runs build/test, iterates on errors.
• 4. Review and approve each Cline step.
• 5. Compare time and effort against manual coding and Copilot Chat.

证据

Cline (autonomous agent): ~8 minutes. It read the existing user service to learn our patterns, planned the change, wrote and edited files, ran our build/test commands, and iterated on errors — with us approving each step.

来源

Copilot Chat (chat-driven, human-coordinated): ~25 minutes.

来源

Copilot’s inline completion is still among the best in the industry — suggestions appear instantly, and they're correct about 85% of the time in our testing.
