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.
