Vercel Bulk Manager has moved to a new URL:
https://vercel-bulk-manager.vercel.app
The old URL (https://vercel-bulk-manager.hyperdyn.tech) is now permanently redirected to the new one.
I want to be transparent at the moment, I can’t afford a custom domain long-term. That said, all services will remain fully online and functional, and you can continue using the tool via the new URL without any issues.
Hope this tool continues to help everyone manage their Vercel projects more easily 
What is Vercel Bulk Manager? (For those who are new)
Vercel Bulk Manager is an all-in-one utility that helps you:
Delete multiple unwanted projects
Remove cluttered deployments
Clean up your Vercel dashboard in just a few clicks
Since Vercel currently doesn’t provide a bulk delete option, this tool securely stores your Vercel token locally in your browser and interacts directly with the Vercel REST API to manage and delete selected projects and deployments.
