Welcome to Ask @rv261457! The reason that traditional custom domain linking on Replit was removed is because traditional repl.co hosting is being removed from Replit. It is being replaced by deployments (replit.app). You can link a custom domain to deployments. Static repls[1] will soon be able to be deployed without a credit card. Non-static repls will require a paid plan to host but will still be able to have custom domains (so long as the repl hosts a website).
