We are deprecating building and hosting data apps on Observable Cloud on the following timeline.

On April 15 (today), we are discouraging deploying new data apps to Observable Cloud by hiding data app-related pages in the Observable workspace for users who do not already have a data app hosted on Observable Cloud. These users will still be able to navigate to data app-related pages directly, and to deploy new data apps from the command line.

On May 15 (in one month), any users that do not already have a data app hosted on Observable Cloud will no longer be able to deploy new data apps.

On October 15 (in six months), or at the end of your Enterprise customer contract if it is later, we will discontinue building and deploying of data apps to Observable Cloud. We will continue serving traffic to data apps hosted on Observable Cloud until at least this date.

If you are a current Observable Cloud customer, we encourage you to migrate any Observable-hosted data apps to your preferred static site hosting provider at your earliest convenience. You can host data apps built with the open-source Observable Framework on a wide variety of providers, including GitHub Pages, Render, Vercel, Cloudflare Pages, and Netlify; see also our guide on automating deploys on GitHub. If you have any questions or concerns, please email support@observablehq.com. After migrating your data app to a new provider, please contact support if you would like us to set up a redirect from Observable Cloud.

For more context on this deprecation, please read our blog post about what’s next.

For Enterprise workspaces, Observable Cloud now lets you embed components from your Observable Framework data apps into other websites and applications. Learn more in the documentation.

• Export JavaScript modules to power interactive components in other apps.

• Export static files (like SVG, PNG, CSV, or JSON) that update whenever your app builds.

• Configure CORS to choose which domains can embed your components.

• Configure URL signing keys to securely embed private components.

• View analytics about which exports are being used.

Also, for all users:

• The “Analytics” tab in data app settings is now called “Pages”.

• Data app sharing settings have been consolidated in the new “Access” tab.

• When new users sign up, it’s easier to join or create a workspace at the same time.

• Detect missing files during build

• Detect file name conflicts during build

• Fix crash during preview with temporary files (e.g., Vim)

See release notes on GitHub for more details.

• You can now import an existing Observable Framework repository from GitHub to create a new data app on Observable without having to go through the command line. Click “+” in the upper right, then “New data app”, or click here.

• The creator of a data app will now receive an email notification if a build fails. If the build was initiated manually by clicking “Deploy”, whoever clicked it will be notified, too.

• We've renamed “Likes” to “Stars”. They function the same as before, just with a fresh name. Starred notebooks are found on the workspace’s “Starred” page or in your personal area; starred data apps are pinned to the top of the data apps list.

Update: As of April 15, 2025, Observable Cloud has been deprecated. Existing instances will continue to function, but new instances cannot be created. Deploy your Observable Framework data app to Observable Cloud to run your data loaders automatically in the background so your dashboards are always fresh and fast. Read more in our founder Mike Bostock’s blog post.

• Deploy from the cloud on schedule, when you push new code, or manually.

• Secrets let you securely give data loaders access to your private data.

• Schedules let you define how often to rebuild your app.

• GitHub integration keeps your app in sync with your repository.

• Segmentation (in beta) lets Enterprise customers build parallel versions of their app for different viewer segments.

Enterprise customers can talk to us to configure an on-premises environment to take advantage of these features without their data ever leaving their system. Contact sales@observablehq.com to get started or to upgrade.
