(1) Full-IDE clouds (Codespaces, Gitpod Flex, Replit, Cursor Cloud). (2) Browser-native sandboxes (StackBlitz WebContainer, CodeSandbox, val.town). (3) AI-first builders (Bolt.new, v0, Lovable, Magic Patterns). (4) Open source and self-hosted (Daytona, DevPod, Coder). Between 2024 and 2025, Glitch, Cloud9, and JetBrains Space disappeared; Gitpod folded its SaaS and bet on Flex (self-hosted); CodeSandbox was acquired by Together AI and pivoted to AI training environments. This piece compares 16 tools on the same axes and gives a decision tree across solo / team / demo / AI-prototype scenarios.

(1) 풀-IDE 클라우드 (Codespaces, Gitpod Flex, Replit, Cursor Cloud), (2) 브라우저-네이티브 샌드박스 (StackBlitz WebContainer, CodeSandbox, val.town), (3) AI-퍼스트 빌더 (Bolt.new, v0, Lovable, Magic Patterns), (4) 오픈소스/셀프호스팅 (Daytona, DevPod, Coder). 2024-2025 사이 Glitch · Cloud9 · JetBrains Space가 사라졌고, Gitpod은 SaaS를 접고 Flex로 셀프호스팅에 베팅했고, CodeSandbox는 Together AI에 인수돼 AI 학습 환경으로 피봇했다. 이 글은 16개 도구를 같은 축으로 정면 비교하고, 1인 / 팀 / 데모 / AI 프로토타입 4가지 시나리오에서 무엇을 골라야 하는지 결정 트리까지 정리한다.
