What it is

Observable provides notebooks for analyzing and visualizing data, explaining ideas with code, and building data-driven workflows or custom apps. Notebooks use cells, display live values beside code, and include a dataflow panel for tracing program behavior. Collaboration includes real-time editing, comments, fork-and-merge workflows, fine-grained access, and version history. Built-in inputs include files, databases, secrets, libraries, and other inputs. Hosted connectors cover Redshift, BigQuery, Databricks, Mongo SQL, MySQL, Oracle, PostgreSQL, Snowflake, and SQL Server. Database clients work from private notebooks; sharing or publishing a connector-based notebook revokes that database access. Observable supports web use, local development, self-hosting, custom domains, public sharing, and deployment. Open-source tooling can generate static sites, and notebooks use readable plain text with web-compatible npm libraries. Free costs nothing. Pro is $2,225 a month as listed, billed $22 per month annually or $25 monthly; Team is $4,045 a month as listed.
