Round-by-round

Visual review of edits

Winner: Cline

Cline's diff approval UI is unmatched. Every change is shown side-by-side, you accept or reject. Claude Code is terminal — diffs are textual.

Long autonomous jobs

Both are API-metered. Both can cost $50-300/mo depending on use. Both 70-80% cheaper through claudeapi.cheap.

CI/CD + automation

Winner: Claude Code

Claude Code can run in headless mode in CI, can be scripted, can be SSH'd. Cline is GUI-bound.

Final verdict

Use Cline for interactive coding sessions where you want to review every diff. Use Claude Code for autonomous overnight work, CI integration, or fan-out tasks. Most serious devs run both. Same sk-cc-... key from claudeapi.cheap powers both at 80% off.
