Observable

Purpose: Observable notebooks are lightweight documents for analyzing and visualizing data, explaining ideas with code, and supporting data-driven workflows with custom apps.
Notebook features: Notebooks use cells, show live values alongside code, and include a dataflow panel to help users understand program behavior.
Collaboration: Observable supports real-time multiplayer editing, fork-and-merge workflows, comments, fine-grained access, and version history.
Data inputs: The product lists file attachments, databases, secrets, libraries, and inputs among its built-in capabilities.
Database integrations: Observable documentation lists hosted connectors for Amazon Redshift, BigQuery, Databricks, Mongo SQL, MySQL, Oracle, PostgreSQL, Snowflake, and SQL Server.
Database access: Database clients are accessible from a user's or team's private notebooks, and sharing or publishing a notebook that uses a database connector revokes that notebook's database access.
Connection security: Observable recommends SSL-encrypted connections and read-only database users; its documentation says SSL connections are encrypted but not yet verified.
Local development and publishing: Observable says notebooks can be used for local development and self hosting, and its free open-source tooling can generate static sites.
File format and libraries: Notebooks use a human-readable plain-text format, and Observable says users can import any npm library that runs on the web.
Plan limits: The pricing page lists 1 GB per month of file attachments for Free and Pro, and 50 minutes per month of compute for Pro.
Team plan limits: The Team plan lists 1 GB per editor per month of file attachments, 50 minutes per editor per month of compute, and private viewers at $10 per viewer per month.
Support: The pricing page lists standard support for Free, priority support for Pro and Team, and dedicated support for Enterprise.
