What is a deployment rollback?
A rollback returns an app to a previous version after a bad deploy. Instead of debugging in production while users wait, you restore the last version that worked, then fix the problem calmly.
Why it changes how you ship
Knowing you can undo a deploy in one step is what makes shipping often feel safe, and that matters double when an AI assistant writes the changes. The safety net is not reviewing every line: it is a preview before the merge and a rollback after it.
How it works on White Ghost
Two ways back: run ghosty rollback from the command line (an assistant can run it for you), or open the app’s Deploys tab and press Redeploy on any previous build. Every build in the history keeps its commit, timing, and log, so you can also see what changed between the good version and the bad one.
