Can I make a template public so other projects can use it?

Yes. By default, templates are scoped to the project that built them, but you can publish a template to make it usable by any other E2B project.

Publishing a template

You can publish a template in two ways:

From the dashboard

Open the Templates tab, find the template, and toggle it to public.

From the CLI

Use the E2B CLI to publish a template you’ve already built:

e2b template publish <template-name>

Using a public template

Once published, other projects can create a sandbox from your template by referencing it with the full namespaced format project-slug/template-name:

e2b sandbox spawn your-project-slug/<template-name>

The same naming format works in the SDKs. Pass project-slug/template-name as the template alias to Sandbox.create().

Unpublishing

To revoke public access, either toggle the template back to private in the dashboard Templates tab, or run:

e2b template unpublish <template-name>

The template stays in your project and remains usable by your project. It is just no longer reachable by others.
