Registration and setup

Estuary Flow is a hosted web application that also offers a robust CLI.

Flow is currently in private beta. Essentially, this means that it's available to you, but new sign-ups are personally reviewed by our team.

Get started with the Flow web application

You can sign up to get started as a Flow trial user by visiting the web application here.

Once you've signed up with your personal information, an Estuary team member will be in touch to activate your account and discuss your business use-case, if applicable.

Get started with the Flow CLI

After your account has been activated through the web app, you can begin to work with your data flows from the command line. This is not required, but it enables more advanced workflows or might simply be your preference.

Flow has a single binary, flowctl.

flowctl is available for:

  • Linux x86-64. All distributions are supported.
  • MacOS 11 (Big Sur) or later. Both Intel and M1 chips are supported.

To install, copy and paste the appropriate script below into your terminal. This will download flowctl, make it executable, and add it to your PATH.

  • For Linux:

    sudo curl -o /usr/local/bin/flowctl -L '' && sudo chmod +x /usr/local/bin/flowctl
  • For Mac:

    sudo curl -o /usr/local/bin/flowctl -L '' && sudo chmod +x /usr/local/bin/flowctl

Alternatively, you can find the source files on GitHub here.

Once you've installed flowctl and are ready to begin working, authenticate your session using an access token.

  1. Sign into the Flow web application.

  2. Click the Admin tab.

  3. On the Admin page, click the CLI-API tab. Copy the token from the Access Token box.

  4. In the terminal of your local development environment, run:

    flowctl auth token --token=<copied-token>

The token will expire after a predetermined duration. Generate a new token using the web application and re-authenticate.

Self-hosting Flow

The Flow runtime is available under the Business Source License. It's possible to self-host Flow using a cloud provider of your choice.


Setup for self-hosting is not covered in this documentation, and full support is not guaranteed at this time. We recommend using the hosted version of Flow for the best experience. If you'd still like to self-host, refer to the GitHub repository or the Estuary Slack.
