deepnote

Deepnote is an open-source notebook platform designed as a Jupyter replacement, adding AI features, real-time collaboration, and a human-readable YAML format. It supports Python, R, and SQL locally via VS Code extensions, with optional cloud scaling through Deepnote Cloud.

What deepnote is

TypeScript-based notebook runtime built on Jupyter kernel with backwards compatibility, featuring reactive cell execution, block-based architecture (@deepnote/blocks), bidirectional notebook conversion (@deepnote/convert supporting .ipynb, .qmd, .py, marimo), and separation of code/output via snapshot files for cleaner version control.

Quickstart

Get the deepnote source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/deepnote/deepnote.gitcd deepnote# follow the project's README for install & configuration

Need it deployed, integrated, or customized instead? DEV.co ships production installs.

Best use cases

Local-first data science workflows with version control

Teams needing human-readable, Git-friendly notebook formats for data analysis and EDA. The .deepnote YAML format and snapshot separation enable cleaner diffs and collaboration compared to Jupyter's JSON .ipynb files.

Jupyter notebook migration and standardization

Organizations running Jupyter who want to adopt a modern notebook standard. Bidirectional conversion between .ipynb and .deepnote allows incremental adoption without forcing notebook rewrites.

AI-assisted data exploration in code editors

Data professionals already using VS Code, Cursor, or Windsurf who want native notebook support with built-in AI agent capabilities without leaving their IDE.

Implementation considerations

  • Jupyter kernel requirement: local Python/R/SQL runtime must be installed and configured; no bundled runtime provided in open-source repo.
  • VS Code extension dependency: local notebook editing requires installing the Deepnote extension; no standalone editor or web UI in open source.
  • Notebook conversion: existing .ipynb files can be converted via @deepnote/convert CLI, but custom cell metadata or third-party Jupyter extensions may not roundtrip cleanly.
  • Reactive execution model differs from Jupyter: blocks auto-re-run on dependency changes; existing notebooks may exhibit unexpected re-execution behavior.
  • Local compute limitations: open-source cannot scale to cloud; teams requiring shared compute must adopt Deepnote Cloud separately.

When to avoid it — and what to weigh

  • Require production ML model serving/inference — Deepnote is a notebook/development environment, not a model serving platform. Productionization requires separate deployment infrastructure.
  • Need browser-based UI in local environment — Current open-source implementation is VS Code extension-only. The notebook UI from Deepnote Cloud is not yet available locally (roadmap item).
  • Depend on closed-source or proprietary extensions — The open-source repository includes only Jupyter-compatible core and VS Code integration. Deepnote Cloud-specific features (managed compute, agent, native integrations) require the commercial platform.
  • Require long-term stability guarantees on format — Repository created September 2025 with active development. .deepnote format specification exists but real-world stability under production load is unproven; breaking changes possible during maturation.

License & commercial use

Apache License 2.0 (Apache-2.0). Permissive OSI-approved license allowing commercial use, modification, and distribution with attribution and liability/warranty disclaimers.

Apache-2.0 permits commercial use, modification, and redistribution provided license and copyright notices are included and changes are documented. However, verify your use case: if you plan to monetize a notebook platform or integrate substantially into a commercial product, conduct IP review. Deepnote Cloud (proprietary) is the company's commercial offering; forking/extending the open-source runtime may create support/trademark considerations—contact Deepnote for clarification on commercial deployment.

Security considerations

No security audit history or disclosures found. Key considerations: notebook execution runs arbitrary Python/R/SQL locally—trust notebook source. Local VS Code setup inherits VS Code security model. Deepnote Cloud (not covered here) is proprietary; its security posture is unknown from this data. If handling sensitive data, review notebook contents before execution and apply OS/network-level isolation as needed.

Alternatives to consider

Jupyter / JupyterLab

Mature, de facto standard for notebooks. No AI agent or reactive execution; heavier setup; JSON format less Git-friendly. Better for teams already invested in Jupyter ecosystem.

Marimo

Reactive Python notebook framework focused on .py files with @app.cell syntax. Lightweight, strong version control story. Lacks SQL, R, and Deepnote's Jupyter compatibility; different learning curve.

Quarto

Document-first notebooks with publication output (HTML, PDF, dashboards). Stronger for reporting and publishing; less interactive for exploration. Not a replacement for dynamic notebooks.

deepnote FAQ

Can I use this without Deepnote Cloud?
Yes. Open-source supports local editing in VS Code and local notebook execution. Cloud features (managed compute, AI agent, integrations, real-time team collaboration) require Deepnote Cloud subscription.
Will my Jupyter notebooks work as-is?
Mostly. Use @deepnote/convert to import .ipynb files to .deepnote format. Jupyter-compatible Python/R/SQL cells will execute; custom cell metadata and third-party extensions may not convert perfectly.
Is this ready for production?
For production notebook *development* workflows, yes—if you accept the young codebase (created Sept 2025) and monitor for breaking changes. Not a production ML serving platform; use tools like FastAPI, BentoML, or cloud ML services for model deployment.
How do I set up team collaboration locally?
Open-source provides no built-in collaboration. Use Git + your VCS platform (GitHub, GitLab) to share .deepnote files. For real-time multi-user collaboration, adopt Deepnote Cloud.
