GitHub Actions has become the de facto standard, but a whole acceleration layer (BuildJet, Depot, Namespace) sits on top of it, while container/programmable pipelines like Earthly and Dagger run a parallel track. On the k8s-native side, Argo Workflows, Tekton, and Drone share the space. IaC has its own market — Spacelift, Garnix, Cycloid — and mobile is still split between Bitrise and Codemagic. In the build-cache layer, Bazel + Buildbarn / BuildBuddy / EngFlow changed the game. This post organizes 20+ platforms into four buckets — managed, self-hosted, k8s-native, and domain-specific — then walks through real strengths, weaknesses, prices, and failure modes for each, finishing with concrete picks for OSS / startup / enterprise / mobile-only teams.

GitHub Actions가 사실상 표준이 됐지만 그 위에 BuildJet·Depot·Namespace 같은 가속 러너 레이어가 깔리고, 옆에는 Earthly·Dagger 같은 컨테이너/프로그래머블 파이프라인이 옆 트랙을 만든다. k8s-네이티브에서는 Argo Workflows·Tekton·Drone이 싸우고, IaC 전용으로는 Spacelift·Garnix·Cycloid가 자리를 굳혔으며, 모바일은 여전히 Bitrise·Codemagic이 양분한다. 빌드 캐시 영역에서는 Bazel + Buildbarn / BuildBuddy / EngFlow가 게임을 바꿨다. 이 글은 20여 개 플랫폼을 매니지드·셀프호스팅·k8s 네이티브·모바일 4분류로 정리한 뒤, 각 도구의 실제 강점·약점·가격·실패 모드를 정리하고, OSS / 스타트업 / 엔터프라이즈 / 모바일 전용 시나리오별 선택 가이드까지 제공한다.
