The Now Platform comprises our API, clients and routing layer. All the individual components are designed to work together in cohesion according to the platform version.


There exist two major platform versions of Now:

  • 1.0 (legacy).
  • 2.0 (default as of 08-11-2018).

As of 2.0, there is no longer a concept of deployment types. All deployments can combine static and dynamic serverless entrypoints.

We recommend migrating to v2 for increased performance, security and new features by following our upgrade guide.

Note: As of the 4th of January 2019, all new users will no longer be able to create deployments on the Now 1.0 platform version.

Version Selection

All individual accounts and teams are always automatically on the latest default version of the platform if created on or after 29-10-2018.

If you already had an account, we recommend upgrading your default version to latest and then specify version inside your repositories for perfect future compatibility.

Team or Account Versioning

In our web dashboard, head to Settings by clicking on your profile picture while logged-in.

Note: please make sure to do this for each context you are interested in selecting a version for (i.e.: individual and/or teams).

If you created your account before 29-10-2018, you will be in the v1 legacy platform. Otherwise, you'll always be on the latest (v2 as of now). We recommend upgrading to v2 once you are confident you have upgraded your projects or pinned them to the corresponding version they are known to work with.

If your account or team is set to the latest, it is still a good idea to always include in now.json what version you want your project to be deployed against.

This ensures that as we continue to make improvements to our platform, your workflows are never disrupted.

Per-project Version Pinning

To maximize predictability and future compliance, we recommend that all your production applications explicitly declare what platform version they are known to work with on now.json:

  "version": 2

If you need to quickly set the platform version when deploying a single file (or if you need to test something), you can use this option in Now CLI:

now --platform-version 2

In also comes with a short version:

now -V 2

If you do not specify a version, Now CLI and Now for GitHub will render a warning. If you do not have time to migrate an application to the latest platform version, you can always specify "version": 1.
