Advertiser disclosure: iTechGuides is reader-supported. Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Concurrent dependency resolution with instruction and build-cache management
  • Rootless execution, distributed workers, and multiple output formats
  • Multi-platform builds across Linux, Windows, and macOS clients
  • Builds Dockerfiles without requiring a Docker daemon
  • Supports Kubernetes, multiple cache modes, and secret mounts
  • Pushes images to major container registries and supports multi-architecture workflows
Cons
  • BuildKit is a builder toolkit, not a general-purpose container runtime
  • Kubernetes CRI implementation is not provided
  • No AI features are included
  • Platform coverage is limited to Linux and self-hosted use
  • Multi-architecture workflows require separate architecture-specific builds
  • Remote layer caching and local base-image caching use different mechanisms
