Observable Framework is our new open-source static site generator for fast, beautiful data apps, dashboards, and reports. Framework combines the power of JavaScript on the front-end for interactive graphics with any language on the back-end for data preparation and analysis.

To learn more about why we made this change, please read our announcement.

Pricing tier changes

• There is now no distinction between viewers and editors — they are all classified as users.

• A new Starter Tier, replacing Free tier — Now includes working in private, unlimited notebooks, one Framework project, and collaboration with up to 5 users.

• Updated Pro Tier — Includes up to 10 users with additional seats available for purchase. Host unlimited Framework projects and continue to work in notebooks. Existing Pro accounts with over 5 users remained on a legacy tier and must switch to the new Pro or Starter tiers in order to host projects.

• Enterprise Tier — Current enterprise customers can continue to access all existing features, but will need to contact sales@observablehq.com to enable Framework project hosting.
