| Fact | BuildKit | SingularityCE |
|---|---|---|
| Integrations | The repository lists Moby and Docker, Tekton Pipelines, Docker buildx, Gitpod, Dagger, and other projects as BuildKit users. | The guide documents GPU access, containerized MPI applications, OCI registries, and Sylabs Container Services Library usage. |
| Purpose | BuildKit converts source code into build artifacts efficiently and repeatably. | SingularityCE creates and runs portable, reproducible containers that package software into a single file. |
| Security model | BuildKit describes itself as secure by default and usable with untrusted sources. | By default, the user inside a container remains the same user as outside and cannot gain additional privilege on the host. |
