Hi! We have a self-hosted Retool instance.
We would like to set up a sandbox instance, so that we can do development and test upgrades.
Does anyone know if it costs extra money to set up a sandbox instance, or can we use the same license?
Hello @latkins, great to see you back in the community forum, it’s been a while! 
To add multiple instances, you'll need to be on our Enterprise plan. If you're interested, you can book a demo with our Sales team for next steps!
