What Observable is

Observable is a notebook platform for analyzing and visualizing data, explaining ideas with code, and building data-driven workflows and custom apps. Notebooks are organized into cells, display live values alongside code, and include a dataflow panel for understanding program behavior. Collaboration features include real-time editing, comments, fork-and-merge workflows, access controls, and version history. Built-in capabilities include file attachments, databases, secrets, libraries, and inputs; hosted connectors cover databases including Redshift, BigQuery, MySQL, PostgreSQL, Snowflake, and SQL Server. Database clients are available in private notebooks, but sharing or publishing a notebook that uses a connector revokes that notebook’s database access. Observable supports web use, local development, and self-hosting, and its free open-source tools can produce static sites. Notebooks use human-readable plain text and can import web-compatible npm libraries. Free includes 1 GB per month of file attachments; Pro costs $22 per user per month billed annually and lists 50 minutes of monthly compute. Free has standard support, while Pro and Team list priority support.
