Cursor raised a Series B at a $9B valuation. Codeium`s Windsurf was acquired by OpenAI in April 2025 for ~$3B. Open-source agents like Cline took up residence inside VSCode. Anthropic`s Claude Code and OpenAI`s Codex CLI created a brand-new category: CLI-first agents. This piece compares 13 tools in one read — full-stack devs, CLI lovers, teams, students, and the budget-conscious all get a recommendation.

Cursor는 Series B에서 90억 달러 가치평가를 받았고, Codeium의 Windsurf는 2025년 4월 OpenAI에 30억 달러로 인수됐다. Cline 같은 오픈소스 에이전트가 VSCode 안에 자리잡았고, Anthropic의 Claude Code와 OpenAI의 Codex CLI는 CLI 에이전트라는 새 카테고리를 만들었다. 이 글은 13개 도구를 한 호흡으로 비교한다 — 누가 풀스택이고, 누가 CLI이고, 누가 팀이고, 누가 무료를 골라야 하는지까지.
