# What is Salesforce sandbox?

> A Salesforce sandbox is a copy of a production org used for development, testing and training. Developer sandboxes copy metadata only; Partial Copy and Full sandboxes also copy some or all records. Changes are built and tested in sandboxes, then deployed to production.

## Why it matters

Sandboxes let teams change things without risking production, but they drift: production keeps changing after a sandbox is refreshed, so a change that works in a sandbox can still fail or overwrite something when it reaches production.

## In SyncOnAI 360

Plans are priced by production org, and each production org's sandboxes are included. Members can deploy to sandboxes freely; production needs an approved proposal. Metadata can be compared between a sandbox and production before a release.
