A Draft form is only visible to you. If anyone visits the public URL, they see a not-found response. You can edit a Draft form freely — add steps, change fields, adjust styling — without any risk of visitors seeing an unfinished version.
A Published form is live at its public URL and actively accepting submissions. You can still edit a published form — every change you save takes effect immediately. If you need to make bigger changes without disrupting visitors, flip the form back to Draft, make your edits, then publish again.
An Archived form can no longer be edited or published. Archiving is not something you do manually — it happens automatically when you declare a winner in an A/B test. The losing variants are archived at that point. An archived form's historical submissions and stats remain available in your dashboard so you can review what happened.
Use the Draft / Published toggle in the builder header. Switching from Draft to Published makes the form live immediately. Switching back to Draft takes it offline immediately. There is no confirmation step, so act deliberately.
