Aden은 Apache License 2.0 하에 배포되는 완전한 오픈소스 프로젝트입니다. 커뮤니티의 기여와 협업을 적극적으로 장려하고 있습니다. + +**Q: Aden은 사용자 데이터를 수집하나요?** + +Aden은 모니터링과 관측성을 위해 토큰 사용량, 지연 시간 메트릭, 비용 추적과 같은 텔레메트리 데이터를 수집합니다. 프롬프트 및 응답과 같은 콘텐츠 수집은 설정 가능하며, 팀 단위로 격리된 상태로 저장됩니다. 셀프 호스팅 환경에서는 모든 데이터가 사용자의 인프라 내부에만 저장됩니다. + +**Q: Aden은 어떤 배포 방식을 지원하나요?** + +Aden은 기본적으로 Docker Compose 배포를 지원하며, 프로덕션 및 개발 환경 설정을 모두 제공합니다. Docker를 지원하는 모든 인프라에서 셀프 호스팅이 가능합니다. 클라우드 배포 옵션과 Kubernetes 대응 설정은 로드맵에 포함되어 있습니다. + +**Q: Aden은 복잡한 프로덕션 규모의 사용 사례도 처리할 수 있나요?** + +네. Aden은 자동 실패 복구, 실시간 관측성, 비용 제어, 수평 확장 지원 등 프로덕션 환경을 명확히 목표로 설계되었습니다. 단순한 자동화부터 복잡한 멀티 에이전트 워크플로까지 모두 처리할 수 있습니다. + +**Q: Aden은 Human-in-the-Loop 워크플로를 지원하나요?** + +네. Aden은 사람의 입력을 받기 위해 실행을 일시 중지하는 개입 노드를 통해 Human-in-the-Loop 워크플로를 완전히 지원합니다. 타임아웃과 에스컬레이션 정책을 설정할 수 있어, 인간 전문가와 AI 에이전트 간의 원활한 협업이 가능합니다. + +**Q: Aden은 어떤 모니터링 및 디버깅 도구를 제공하나요?** + +Aden은 다음과 같은 포괄적인 관측성 기능을 제공합니다. 실시간 에이전트 실행 모니터링을 위한 WebSocket 스트리밍, TimescaleDB 기반의 비용 및 성능 메트릭 분석, Kubernetes 연동을 위한 헬스 체크 엔드포인트, 예산 관리, 에이전트 상태, 정책 제어를 위한 19개의 MCP 도구 + +**Q: Aden은 어떤 프로그래밍 언어를 지원하나요?** + +Aden은 Python과 JavaScript/TypeScript SDK를 모두 제공합니다. Python SDK에는 LangGraph, LangFlow, LiveKit 연동 템플릿이 포함되어 있습니다. 백엔드는 Node.js/TypeScript로 구현되어 있으며, 프론트엔드는 React/TypeScript를 사용합니다. + +**Q: Aden 에이전트는 외부 도구나 API와 연동할 수 있나요?** + +네. Aden의 SDK로 래핑된 노드는 기본적인 도구 접근 기능을 제공하며, 유연한 도구 생태계를 지원합니다. 노드 아키텍처를 통해 외부 API, 데이터베이스, 다양한 서비스와 연동할 수 있습니다. + +**Q: Aden에서 비용 제어는 어떻게 이루어지나요??** + +Aden은 지출 한도, 호출 제한, 자동 모델 다운그레이드 정책 등 세밀한 예산 제어 기능을 제공합니다. 팀, 에이전트, 워크플로 단위로 예산을 설정할 수 있으며, 실시간 비용 추적과 알림 기능을 제공합니다. + +**Q: 예제와 문서는 어디에서 확인할 수 있나요?** + +전체 가이드, API 레퍼런스, 시작 튜토리얼은 [docs.adenhq.com](https://docs.adenhq.com/) 에서 확인하실 수 있습니다. 또한 저장소의 `docs/` 디렉터리와 종합적인 [DEVELOPER.md](DEVELOPER.md) 가이드도 함께 제공됩니다. + +**Q: Aden에 기여하려면 어떻게 해야 하나요?** + +기여를 환영합니다. 저장소를 포크하고 기능 브랜치를 생성한 뒤 변경 사항을 구현하여 Pull Request를 제출해 주세요. 자세한 내용은 [CONTRIBUTING.md](CONTRIBUTING.md)를 참고해 주세요. + +**Q: Aden은 엔터프라이즈 지원을 제공하나요?** + +엔터프라이즈 관련 문의는 [adenhq.com](https://adenhq.com)을 통해 Aden 팀에 연락하시거나, 지원을 위해 [Discord community](https://discord.com/invite/MXE49hrKDk)에 참여해 주시기 바랍니다. + +--- + +
