Observable is a platform for building and hosting data applications, such as data notebooks and dashboards, offered by Observable, Inc. Users bring data from their own sources into notebooks and share the results with colleagues or publicly. The platform is delivered as a cloud service; according to the vendor, Observable Cloud can also deploy apps inside a customer's own on-premises or private cloud environment.
Observable, Inc. is based in San Francisco in the United States and therefore falls under US jurisdiction, including the CLOUD Act. A security document from the company states that production infrastructure runs on Heroku, with Postgres databases at Heroku and storage at AWS, and that data a user pulls into a notebook flows from the source to the browser without being stored on Observable's systems. That document may be out of date. A privacy policy effective June 2025 states that Observable collects only the data it needs and does not sell personal information. No GDPR data processing agreement or EU hosting option is documented; ask the vendor.
