Fetching and Using Environments

Once a pool is provisioned and has available instances, your team can start using them.

Fetching an environment

Fetch an environment from a pool — select the pool and set how long you need it

Click Fetch Sandbox from the Pools page or from the DEV ENVIRONMENTS panel on the right. The dialog shows all pools with their current availability — how many environments are ready and the total capacity.

Select a pool and set the Expiration Hours — this is how long the environment will be assigned to you before it expires and returns to the pool. Click Fetch Sandbox to grab it.

Once fetched, you receive a password reset email from Salesforce to set up your credentials. The environment is immediately assigned to you.

You can see all environments assigned to you under Dev > My Orgs > Assigned to Me in the sidebar.

Managing pool instances

Pool detail view showing individual instances with status, assignment, and expiry countdown

Click any pool name on the Pools page to see all its instances. Each instance shows:

• Its current status — Available, Assigned, Provisioning, or Expired
• Who it is assigned to (if anyone)
• When it expires, with a countdown (e.g., "2d left", "1h left")
• Action buttons to open, extend, or delete it

Switch to the Pool Config (YAML) tab to view or edit the pool's configuration.

Where instances come from

The Provisioned from card shows the base each instance is built on, its Salesforce id, and the owning org

The pool detail page shows a Provisioned from card — the base each instance in the pool is built on. What it shows depends on the pool type:

Pool type	Provisioned from	Shown as
Sandbox	A source sandbox it clones	the sandbox name, its SandboxInfo id, and the owning org
Sandbox	Production (no source sandbox)	Production and the license type
Scratch org	A base snapshot	the snapshot name, its OrgSnapshot id, and the owning org
Scratch org	A fresh scratch definition (no snapshot)	Scratch definition and the definition file path

The base is read-only here — a scratch org's snapshot lives in its scratch definition file in the repository, and a sandbox's source is set in the pool configuration. The Salesforce id is looked up live and shown alongside the name when the base exists; the name is shown on its own when it does not. To change the base, edit the pool's definition (see Creating and configuring pools).

Extending an environment

Extend the expiration of an assigned environment by a specified number of days

If you need more time with an assigned environment, click the extend action on the instance row. The dialog shows the current expiry date and lets you add days. The new expiry is previewed before you confirm.

This is useful when a feature takes longer than expected or when you need to keep an environment around for a demo or review.

Returning an environment

When your lease expires, the environment is automatically returned to the pool and made available for others. You can also return it early from the pool detail page by unassigning it.

Returned environments may be refreshed, reused, or deleted depending on the pool's expiration strategy.
