Vercel's platform enables the deployment of modern websites and applications without requiring complicated server configuration, automatically configuring DNS records and issuing free wildcard SSL certificates through Let's Encrypt, a non-profit organization that aims to encrypt the web. By utilizing ACME protocol and presenting challenges to verify domain ownership, Vercel automates the process of obtaining and renewing SSL certificates, making it easier for developers to focus on their core applications rather than server setup. The platform supports automatic HTTPS-enabled deployments for both staging and production environments, allowing users to test changes before merging them into the default branch, and ensures that certificates are immediately set up against the chosen domain name, enabling a secure web experience.
