Does Personio have anything comparable to a Salesforce sandbox?

When I want to develop for Salesforce, I would not normally develop against the production environment, but rather create a "sandbox" which creates a copy of the Salesforce "org" including all the metadata (i.e. any customizations of the org, including any custom objects and fields) so I can develop and test a solution against the sandbox before putting it into production. For most sandboxes, real data would not be included (so no risk of corruption or exposure) and while there are limits to how many sandboxes we can have for an org, the sandbox can be kept as long as we need it.

Is there anything comparable for Personio, or do I need to choose between developing against production orgs or trial orgs which won't have the custom metadata and won't last a long time?
