## What it is
BuildKit is a concurrent, cache-efficient toolkit for converting source code into build artifacts such as OCI container images. It powers Docker's default build engine and supports pluggable frontends including Dockerfiles, with rootless execution and distributed workers.

## Use cases
- build OCI container images efficiently
- speed up Docker builds with better caching
- build container images without root privileges
- export build cache to a registry for CI
- build images from a custom frontend format
- run parallel container build jobs

## When to choose
- you need fast, cache-efficient container image builds
- you want rootless or daemonless image building
- you need advanced Dockerfile features like cache and secret mounts
- you want to embed image building into your own tooling

## When to avoid
- you only need to run containers, not build images
- you are locked into a legacy Docker build workflow that predates BuildKit
- you need a full CI/CD pipeline system rather than a build engine
