How do I use the Dockerfile Generator?

Multi-stage builds dramatically shrink final image size The Node template uses npm ci for reproducible builds The Go template uses distroless for minimal attack surface

Is the Dockerfile Generator free and private?

Yes — it runs in your browser, requires no signup for basic use, and your data never leaves your device. Docker images are stored as tar archives of layer diffs — pulling an image downloads only the layers you don't already have locally.
