When migrating a website to a new server, one of the annoying parts is testing the site before updating DNS records.
Normally you have a few options:
• edit your local hosts file
• use curl with --resolve
• temporarily change DNS
The problem is that these approaches either:
only work on your machine
require admin privileges
are difficult to share with teammates or clients
So I built a small tool that makes this easier.
It generates a preview link that routes a domain to a specific server IP while preserving the original Host header.
This lets you preview a website exactly as it would behave after DNS changes, without editing your hosts file.
