PyCharm and Visual Studio Code for API services

With Zato 3.0, we are excited to announce some popular development environments now have integrated support for hot-deploying Zato services directly from the comfort of your favorite text editor.

Hot-deployment obviates the need to visit the administration GUI while modifying an in-development service, or requiring filesystem access to the machines hosting your cluster, the primary options available for rapid deployment prior to our new support for IDE extensions.

Initially we are releasing extensions for PyCharm and Visual Studio Code while focusing on a great story around hot-deployment, however this is only the start. We have some very exciting integrations planned to simplify your Zato development workflow coming soon!


As our plugin is published in the JetBrains Plugin Repository, installation on PyCharm is achieved simply by visiting Preferences -> Plugins, then clicking Browse repositories:

Next, search for Zato and click the Install button:

Once installation completes, visit Preferences -> Languages & Frameworks -> Zato to populate connection information for your development cluster:

Finally, with a service module open in the editor, visit Tools -> Upload to default Zato server to trigger upload:

Alternatively, automatic deployment can be triggered on every file save, by including the magic ide-deploy=True marker comment somewhere in the file:

Success is indicated in the status bar at the bottom of the window:

Visual Studio Code

With Visual Studio Code, simply visit the Extensions Marketplace either in your browser, or within the application by pressing Ctrl+Shift+X hot-key:

After installation completes, a quick visit to the settings panel (Ctrl+,) is needed to configure your cluster connection:

While editing any Python script, you can deploy to the configured Zato cluster with a simple icon click, by pressing the Ctrl+Shift+L hotkey:

Just as in PyCharm, automatic deployment can also be triggered on file save, by including the magic ide-deploy=True marker comment somewhere in the file:

Success is indicated through a status panel that appears following activation:

For more information, please refer to the setup instructions provided in the extension's, which is presented as part of the Marketplace user interface embedded within Visual Studio Code.

This sounds great, but I'm on an older release

Don't worry, we have you covered! The [Zato 2.0 documentation chapter on IDE integration]/en/docs/3.2/index.html) includes a procedure for modifying older clusters to support the new endpoint. The process only takes a few moments, and the result works just great.


This release marks the foundational work for many exciting future integrations. We are already playing with ideas, or actively planning future support for:

  • Integrated service name completion for self.invoke()
  • In-IDE API specification documentation browser
  • In-IDE service invoker
  • Zato API code completion
  • Server log viewer

Stay tuned for more information on when these features may land!
