# How can I get Crisp Essentials for my development or staging website? (sandbox mode)

****A lot of complex websites run over multiple environments (production, staging, development). While it is okay to run the same Crisp website on all your environments, some may prefer to have a separate "sandbox" Crisp website for their development and staging environments.****

# How does it work?

Crisp offers a ****free Staging environment**** for any workspace subscribed to a paid Crisp ****Essentials**** or ****Plus**** plan.

This allows you to test and integrate all Crisp features in a dedicated development/staging mode (for instance: Crisp Chatbox JS SDK, Crisp Automated Campaigns, etc.), without "polluting" your primary production website Crisp team.

| Your Staging will match the subscription of your main workspace (Essentials and Plus exclusively), and remain active for as long as you remain on a paid subscription.

# How do I create a sandbox mode workspace?

The sandbox mode has to be manually validated by our team. You will need to [contact our chat support](https://crisp.chat/en/contact/) so that we can enable it for you.

****Before you contact our support:****

* Create a second website, subscribed to Crisp Free plan
* Name it similarly to your main Essentials/Plus workspace, with a `` `Staging` `` or `` `Sandbox` `` suffix, e.g. "CookieFactory Staging"

****While contacting our support:****

* Provide your workspace name;
* Provide your workspace domain;
* Submit the value of your `` `CRISP_WEBSITE_ID` `` (it can be found in your chatbox code)

****Upon the support accepting your request to create a sandbox website:****

* Upgrade the second website to Crisp Essentials (you will not be charged immediately);
* Inform the support the second website has been upgraded;
* Wait for the support to apply the sandbox mode to this website (you will not pay anything);
* Logout and login to your Crisp app, and enjoy sandbox mode on your development or staging website

# What are the requirements to get a sandbox subscription?

****In order to get your development or staging Crisp website subscribed to a sandbox subscription, please check that the following requirements are met:****

1. Your primary (production) Crisp website has an active Crisp Essentials subscription;
2. Your secondary (staging or development) Crisp website has the name of your primary website, ending with "dev" or "staging"

# What's the difference of a sandbox versus a normal plan subscription?

There's not much difference between a full subscription, and a free sandbox subscription, other than the free sandbox subscription should only be used for development purposes on your local development website, or your staging website.

****Some limitations are applied in the way Crisp can be used in the sandbox environment:****

1. A sticky banner reminds you that the website is running in sandbox mode (this cannot be closed or hidden);
2. Each message can only be sent after a few second through the inbox (a modal will open, prompting you to confirm that you want to send the message);
3. The number of recipients you can send a campaign to is limited, well under normal limits (read our [article about campaign recipient limits](/en/article/what-are-email-campaigns-recipient-limits-cmvcqw/) )
