Self-Host with Docker

Docker is a popular way to package and run applications. This guide covers running your App Builder project in a Docker container.

Export your project

Use Export → Download Code in the builder to download your project. Unzip it on your machine.

Build the Docker image

From the project root (with a Dockerfile in place):

docker build -t my-seamai-site .

If your template does not include a Dockerfile, add one that installs dependencies, builds the project, and starts the app.

Run the container

docker run -p 3000:3000 my-seamai-site

Visit http://localhost:3000 to verify the site.

Environment variables

If your project needs environment variables, pass them with -e (see Docker environment variables):

docker run -p 3000:3000 -e MY_API_KEY=... my-seamai-site
