Deepnote
Apache-2.0Deepnote is an open-source data notebook that replaces Hex with clean YAML files, local IDE workflows, and reactive Python and SQL execution.

Overview
Deepnote is an interactive data notebook platform built around a human-readable, block-based file format. Rather than trapping code inside opaque JSON notebooks or proprietary cloud workspaces, it stores notebook logic in YAML files that isolate code from execution outputs. This structure allows developers to version analytical workflows in standard code editors while retaining the option to push projects to a shared cloud runtime.
Why Deepnote instead of Hex
Hex anchors modern cloud data exploration by combining warehouse SQL queries with interactive widgets and published data apps, but it locks the entire workflow into a proprietary hosted engine. Notebook logic lives in a closed database, preventing teams from auditing changes through standard Git diffs or running computations without sending raw data through external infrastructure. Deepnote mitigates that operational risk by decoupling the notebook representation from execution. Its open-source core defines notebooks as .deepnote YAML files alongside companion snapshot files, allowing teams to version pipelines in internal repositories and run queries locally in VS Code or Cursor without cloud data transmission.
Hex retains an edge in app publishing and granular stakeholder permissions for central business intelligence teams. Deepnote narrows that reporting gap with reactive block execution and scheduled runs, though its hybrid model requires trade-offs. While exploratory code and sensitive client datasets remain on local machines, real-time multiplayer editing and cloud compute still require syncing projects to Deepnote Cloud. For agencies handling strict client confidentiality and ops leads seeking vendor independence, Deepnote delivers collaborative analytics without surrendering file ownership.
What it does well
- Human-readable project schema: Uses clean
.deepnoteYAML files that isolate outputs into separate snapshot documents, eliminating Git merge conflicts during code reviews. - Multi-format conversion: Converts notebooks between Jupyter, Quarto, Marimo, and Percent formats via
@deepnote/convert, simplifying cross-team asset sharing. - Reactive block execution: Recalculates downstream dependencies automatically through
@deepnote/reactivitywhenever inputs change, preventing stale calculations.
