Hi @fohoov! You could use the vercel alias command in the CLI to assign consistent domains to each new preview deployment of the frontend and backend projects. A custom workflow could work well for this if you want to automate.
As another option, you could take advantage of the predictable URL with Git branch and branch-specific preview environment variables.
There’s also a new option to automatically skip unnecessary deployments in monorepos which could help you avoid unnecessary deployments.
