The modern data visualization and notebook platform for the web
Observable is a cloud-based, collaborative notebook platform for data visualization, exploration, and analysis. Created by Mike Bostock (the creator of D3.js), Observable lets developers and data analysts weave together JavaScript, Markdown, HTML, and SQL in reactive notebooks that update automatically as you interact with them. Teams use Observable to build interactive dashboards, exploratory analyses, and production-ready data apps — all in the browser with no backend infrastructure required.
Cells re-run automatically when data or inputs change, making it easy to build live, interactive explorations without manual refreshes
Built-in support for Observable Plot, D3.js, and other leading visualization libraries for creating rich, expressive charts and graphics
Connect directly to Snowflake, DuckDB, PostgreSQL, Databricks, and other data sources without leaving the notebook
Collaborate in real time with teammates via multiplayer code editing, comments, and automatic version history
Build and deploy production-grade data apps and dashboards as static sites using the open-source Observable Framework
AI-powered code completion and generation helps you write JavaScript, SQL, and visualization code faster
Git-style forking and version history let you freely experiment and roll back changes at any time
Rapidly prototype charts and dashboards with live data connections and reactive inputs like sliders, dropdowns, and search boxes
Combine narrative text with dynamic visualizations to publish interactive reports and explanatory data stories
Build and share scheduled, always-fresh dashboards connected to Snowflake, Postgres, or DuckDB for business intelligence
Fork community notebooks, experiment with live code, and learn D3 or Observable Plot in a hands-on browser environment
Schedule notebooks to run automatically and keep dashboards and reports up to date with fresh data
Use Observable Framework to compile notebooks into fast, deployable static data apps with no backend infrastructure

AI-powered SQL client that turns natural language into database queries
