Gearset’s comparison UI highlights all changed, new and deleted metadata items, so you can easily see the differences between your environments. This means you don’t need to rely on manual, time-consuming and error-prone tracking. Plus, you can easily spot when an org is getting out of sync and use the comparison to align your environments.
Most Salesforce deployment tools (change sets, Ant migration tool, Workbench, or even DevOps Center) don't compare the metadata in your source and target orgs.
