Is there any way to create new project (i.e. a new folder with a new notebook underneath) in marimo UI?

[twisteria]

I want to create new project in marimo and surprised the top page UI does not have "create new folder" button, even though FILES panel (what you see left side when you open notebook) does.
In the contrary, top page has huge icon to "create new notebook" which I could not find in FILES panel.
So, what is the philosophy of creating / managing multiple projects in marimo?
I'm running marimo on Docker. Should creating a whole new container per project be the answer???

Short answer: No "Create Folder" on home page, and no, don't spin up containers per project.

Marimo treats notebooks as plain .py files. Project management happens at the filesystem/tooling level, not in the UI.

The practical approach:

# Create project with uv, then edit notebooks inside
uv init my-project && cd my-project
uv add marimo
uv run marimo edit notebook.py

For Docker: Mount your projects directory, organize on host:

docker run -v /path/to/projects:/home/marimo/projects -p 2718:2718 marimo edit --host 0.0.0.0

Home page creates notebooks (the fundamental unit). FILES panel creates folders for organizing assets within a notebook's context. Different purposes.

You can check these docs:

• Notebooks in existing projects
• Using uv

I hope that answers your question, good luck!

Additionally, you can organize Marimo notebooks into different directories by adding a folder path to their name. This is done in the notebook UI.

For example:

my-notebook.py -> Marimo creates a notebook called "my-notebook.py" in the project's root folder.

project-1/my-notebook.py -> Marimo creates a new directory called "project-1" and saves "my-notebook.py" there.
