Git-free marimo notebook sharing via GitHub

Git-free marimo notebook sharing via GitHub.

Mooring is a single-file app (mooring.pyz / mooring.exe) that lets a team of data analysts pull, edit, and push marimo notebooks stored in a shared GitHub repo — without git installed on their machines. All sync happens over the GitHub REST API; the only requirement on an analyst's machine is Python 3.12.

Double-clicking the app opens a local browser hub: log in to GitHub with a one-time device code, see every team notebook with its sync status, pull the latest, open notebooks in the bundled marimo editor, and push your changes back — one commit per file, with conflicts detected and resolved per file (never silently overwritten).

How it works

• One shared team repo (e.g. your-org/notebooks) holds notebooks/ and data/ folders. Everyone pulls from and pushes to it.
• No git anywhere. Pull walks the repo tree via the GitHub Git Data API and downloads only changed blobs; push uses the Contents API with the file's last-known SHA, so GitHub itself rejects writes that would clobber someone else's change.
• Conflicts are explicit. Pull never overwrites local edits; push blocks conflicted files, offering per-file resolution.
• Frozen package stack. Notebooks can import anything bundled into the artifact (polars, altair, plotly, openpyxl, fastexcel, requests, plus the standard library). There is no pip at runtime.

Documentation

Full docs live in docs/ and build into a searchable site with zensical:

• For users — install Python, run the app, and pull / edit / push notebooks (daily workflow, conflicts, CLI).
• For admins — set up a team: GitHub setup (the repo, OAuth app, client id, scopes), configuration, and build & distribute.
• For developers — architecture and contributing.

Build & preview the docs

uv sync
uv run zensical serve     # live-reloading preview at a local URL
uv run zensical build     # static site into ./site

.github/workflows/docs.yml publishes the site to GitHub Pages on every push to the default branch.

Develop

uv sync                                  # install everything
uv run pytest                            # unit tests (no network needed)
uv run ruff check src tests              # lint
uv run mooring hub                       # run the hub from source

See contributing for the architecture, integration testing, and project conventions.
