Try it safely

Three steps: look first, then change one project, then all of them. Each step can be undone (Auto-deploy off and on).

1. Only look#

Opening the app changes nothing on Vercel, Render or GitHub. It reads your projects and shows which ones still deploy on every push. Nothing changes until you press Turn off auto-deploy or Deploy and confirm.

The same in Terminal. Every command here only reads:

deploys doctor            # what is connected
deploys vercel list       # AUTO (owner/repo) or manual, per project
deploys render list       # auto-deploy setting per service
deploys changed           # what is merged on GitHub and not live
deploys triggers          # builds in the last 24 h nobody started from here, workflows that deploy
deploys deploy-changed    # without --yes: only shows what it would deploy

deploys triggers matters most. A GitHub workflow or a deploy hook that deploys by itself keeps building after auto-deploy is off.

2. One project#

Pick a project you can afford to have down for a few minutes.

Vercel

deploys vercel autodeploy-off my-project         # removes the Git connection, remembers the repo
deploys vercel deploy my-project --preview       # a preview first, not production
deploys vercel deploy my-project                 # then production
deploys watch my-project                         # until it is live or failed

Render

deploys render autodeploy-off my-service         # sets auto-deploy to Off
deploys render deploy my-service
deploys watch my-service

In the app: right-click the row for Preview and Roll back. If something is wrong, deploys vercel rollback my-project or deploys render rollback my-service puts the deploy that was live before back.

Push a commit to the project's repo and check that no build starts. With the GitHub CLI logged in, deploys changed then lists the project as waiting.

3. All projects#

deploys vercel autodeploy-off --all
deploys render autodeploy-off --all

Or press Turn off auto-deploy in the app. It lists every affected project before you confirm.

From then on, one daily deploy is enough. In the app: Select all changed, then Deploy. In Terminal: deploys deploy-changed --yes.
