Claude Codeの代替ツール
同じワークフローを実行する低コストのモデルAPIを含む、ターミナル優先およびエディタベースのコーディングエージェントです。
私たちの結論
Codex is the most direct alternative as another terminal agent. Cursor and GitHub Copilot suit developers who prefer an editor, and opencode paired with a low-cost model such as GLM keeps costs down. Pick based on where you like to work, then compare usage limits.
