# Dockerfile starter generator — no upload

> Generate a starter Dockerfile for common stacks (Node, Python, Go, and more) in your browser. Nothing is uploaded — the file is built on your device.

Generate a sensible starter Dockerfile for common stacks like Node, Python, and Go, with multi-stage build patterns where they help. It's produced in the browser with no upload.

Writing a Dockerfile from scratch means remembering base images, layer ordering, and multi-stage tricks. A generated starter gets the structure right so you can focus on your app's specifics.

Validate a companion Compose file with the Docker Compose validator, and scaffold the rest with the .gitignore and LICENSE generators.

## How to

1. **Pick a stack.** Choose your language/runtime.
2. **Set options.** Adjust the base image and port as needed.
3. **Copy.** Copy the Dockerfile into your project.

## FAQ

### Does it use multi-stage builds?

For compiled and build-step stacks it can produce a multi-stage Dockerfile, keeping the final image small by leaving build tools out of the runtime layer.

### Is this production-ready?

It's a solid starting point following common best practices; you should still review the base image tag, ports, and security for your specific app.

### Is anything uploaded?

No. The Dockerfile is generated locally in the tab.
